  • How to genrate a monochrome bit mask for a 32bit bitmap

    - by Mordachai
    Under Win32, it is a common technique to generate a monochrome bitmask from a bitmap for transparency use by doing the following: SetBkColor(hdcSource, clrTransparency); VERIFY(BitBlt(hdcMask, 0, 0, bm.bmWidth, bm.bmHeight, hdcSource, 0, 0, SRCCOPY)); This assumes that hdcSource is a memory DC holding the source image, and hdcMask is a memory DC holding a monochrome bitmap of the same size (so both are 32x32, but the source is 4 bit color, while the target is 1bit monochrome). However, this seems to fail for me when the source is 32 bit color + alpha. Instead of getting a monochrome bitmap in hdcMask, I get a mask that is all black. No bits get set to white (1). Whereas this works for the 4bit color source. My search-foo is failing, as I cannot seem to find any references to this particular problem. I have isolated that this is indeed the issue in my code: i.e. if I use a source bitmap that is 16 color (4bit), it works; if I use a 32 bit image, it produces the all-black mask. Is there an alternate method I should be using in the case of 32 bit color images? Is there an issue with the alpha channel that overrides the normal behavior of the above technique? Thanks for any help you may have to offer! ADDENDUM: I am still unable to find a technique that creates a valid monochrome bitmap for my GDI+ produced source bitmap. I have somewhat alleviated my particular issue by simply not generating a monochrome bitmask at all, and instead I'm using TransparentBlt(), which seems to get it right (but I don't know what they're doing internally that's any different that allows them to correctly mask the image). It might be useful to have a really good, working function: HBITMAP CreateTransparencyMask(HDC hdc, HBITMAP hSource, COLORREF crTransparency); Where it always creates a valid transparency mask, regardless of the color depth of hSource. Ideas?

  • Computing "average" of two colors

    - by Francisco P.
    This is only marginally programming related - has much more to do w/ colors and their representation. I am working on a very low level app. I have an array of bytes in memory. Those are characters. They were rendered with anti-aliasing: they have values from 0 to 255, 0 being fully transparent and 255 totally opaque (alpha, if you wish). I am having trouble conceiving an algorithm for the rendering of this font. I'm doing the following for each pixel: // intensity is the weight I talked about: 0 to 255 intensity = glyphs[text[i]][x + GLYPH_WIDTH*y]; if (intensity == 255) continue; // Don't draw it, fully transparent else if (intensity == 0) setPixel(x + xi, y + yi, color, base); // Fully opaque, can draw original color else { // Here's the tricky part // Get the pixel in the destination for averaging purposes pixel = getPixel(x + xi, y + yi, base); // transfer is an int for calculations transfer = (int) ((float)((float) (255.0 - (float) intensity/255.0) * (float) color.red + (float) pixel.red)/2); // This is my attempt at averaging newPixel.red = (Byte) transfer; transfer = (int) ((float)((float) (255.0 - (float) intensity/255.0) * (float) color.green + (float) pixel.green)/2); newPixel.green = (Byte) transfer; // transfer = (int) ((float) ((float) 255.0 - (float) intensity)/255.0 * (((float) color.blue) + (float) pixel.blue)/2); transfer = (int) ((float)((float) (255.0 - (float) intensity/255.0) * (float) color.blue + (float) pixel.blue)/2); newPixel.blue = (Byte) transfer; // Set the newpixel in the desired mem. position setPixel(x+xi, y+yi, newPixel, base); } The results, as you can see, are less than desirable. That is a very zoomed in image, at 1:1 scale it looks like the text has a green "aura". Any idea for how to properly compute this would be greatly appreciated. Thanks for your time!

  • TinyMCE is glitchy/unusable in IE8

    - by Force Flow
    I'm using the jQuery version of TinyMCE 3.3.9.3 In firefox, it works fine (10 sec video depicting it in use): http://www.youtube.com/watch?v=TrAE0igfT3I In IE8 (in IE8 standards mode), I can't type or click any buttons. However, if I use ctrl+v to paste, then I can start typing, but the buttons still don't work (a 45 sec video depicting it in use): http://www.youtube.com/watch?v=iBSRlE8D8F4 The jQuery TinyMCE demo on TinyMCE's site works for me in IE8. Here's the init code: $().ready(function(){ function tinymce_focus(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#6478D7'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#6478D7'}); } function tinymce_blur(){ $('.defaultSkin table.mceLayout').css({'border-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceFirst td').css({'border-top-color' : '#93a6e1'}); $('.defaultSkin table.mceLayout tr.mceLast td').css({'border-bottom-color' : '#93a6e1'}); } $('textarea.tinymce').tinymce({ script_url : 'JS/tinymce/tiny_mce.js', theme : "advanced", mode : "exact", invalid_elements : "b,i,iframe,font,input,textarea,select,button,form,fieldset,legend,script,noscript,object,embed,table,img,a,h1,h2,h3,h4,h5,h6", //theme options theme_advanced_buttons1 : "cut,copy,paste,pastetext,pasteword,selectall,|,undo,redo,|,cleanup,removeformat,|", theme_advanced_buttons2 : "bold,italic,underline,|,bullist,numlist,|,forecolor,backcolor,|", theme_advanced_buttons3 : "", theme_advanced_buttons4 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "none", theme_advanced_resizing : false, //plugins plugins : "inlinepopups,paste", dialog_type : "modal", paste_auto_cleanup_on_paste : true, setup: function(ed){ ed.onInit.add(function(ed){ //check for addEventListener -- primarily supported by firefox only var edDoc = ed.getDoc(); if ("addEventListener" in edDoc){ edDoc.addEventListener("focus", function(){ tinymce_focus(); }, false); edDoc.addEventListener("blur", function(){ tinymce_blur(); }, false); } }); } }); }); Any ideas as to why it's not working in IE8? [edit]: stripping everything out of the init (leaving just script_url and theme) results in the same symptoms

  • No transperancy in Bitmap loading from MemoryStream

    - by Jogi Joseph George
    Please see the C# code. When i am writing a Bitmap to a file and read from the file, i am getting the transperancy correctly. using (Bitmap bmp = new Bitmap(2, 2)) { Color col = Color.FromArgb(1, 2, 3, 4); bmp.SetPixel(0, 0, col); bmp.Save("J.bmp"); } using (Bitmap bmp = new Bitmap("J.bmp")) { Color col = bmp.GetPixel(0, 0); // ------------------------------ // Here col.A is 1. This is right. // ------------------------------ } But if I write the Bitmap to a MemoryStream and read from that MemoryStream, the transperancy has been removed. All Alpha values become 255. MemoryStream ms = new MemoryStream(); using (Bitmap bmp = new Bitmap(2, 2)) { Color col = Color.FromArgb(1, 2, 3, 4); bmp.SetPixel(0, 0, col); bmp.Save(ms, ImageFormat.Bmp); } using (Bitmap bmp = new Bitmap(ms)) { Color col = bmp.GetPixel(0, 0); // ------------------------------ // But here col.A is 255. Why? i am expecting 1 here. // ------------------------------ } I wish to save the Bitmap to a MemoryStream and read it back with transperancy. Could you please help me?

  • How can I simply change a class variable from another class in ObjectiveC?

    - by Daniel
    I simply want to change a variable of an object from another class. I can compile without a problem, but my variable always is set to 'null'. I used the following code: Object.h: @interface Object : NSObject { //... NSString *color; //... } @property(nonatomic, retain) NSString* color; + (id)Object; - (void)setColor:(NSString*)col; - (NSString*)getColor; @end Object.m: +(id)Object{ return [[[Object alloc] init] autorelease]; } - (void)setColor:(NSString*)col { self.color = col; } - (NSString*)getColor { return self.color; } MyViewController.h #import "Object.h" @interface ClassesTestViewController : UIViewController { Object *myObject; UILabel *label1; } @property UILabel *label1; @property (assign) Object *myObject; @end MyViewController.m: #import "Object.h" @implementation MyViewController @synthesize myObject; - (void)viewDidLoad { [myObject setColor:@"red"]; NSLog(@"Color = %@", [myObject getColor]); [super viewDidLoad]; } The NSLog message is always Color = (null) I tried many different ways to solve this problem, but no success. Any help would be appreciated.

  • How do I DRY up business logic between sever-side Ruby and client-side Javascript?

    - by James A. Rosen
    I have a Widget model with inheritance (I'm using Single-Table Inheritance, but it's equally valid for Class-per-Table). Some of the subclasses require a particular field; others do not. class Widget < ActiveRecord ALL_WIDGET_TYPES = [FooWidget, BarWidget, BazWidget] end class FooWidget < Widget validates_presence_of :color end class BarWidget < Widget # no color field end class BazWidget < Widget validates_presence_of :color end I'm building a "New Widget" form (app/views/widgets/new.html.erb) and would like to dynamically show/hide the color field based on a <select> for widget_type. <% form_for @widget do |f| %> <%= f.select :type, Widget::ALL_WIDGET_TYPES %> <div class='hiddenUnlessWidgetTypeIsFooOrBaz'> <%= f.label :color %> <%= f.text_field :color %> </div> <% end %> I can easily write some jQuery to watch for onChange events on widget_type, but that would mean putting some sort of WidgetTypesThatRequireColor constant in my Javascript. Easy enough to do manually, but it is likely to get disconnected from the Widget model classes. I would prefer not to output Javascript directly in my view, though I have considered using content_for(:js) and have a yield :js in my template footer. Any better ideas?

    input:required{ background-color:#f00; } input:required label{ color: #FF3434; } I have the above CSS code currently for my form, I want to be able to make the label red when the field is required. My input field is: <label for="frmComTelephone">Telephone</label> <input type="number" name="Telephone" id="frmComTelephone"/> But that CSS isn't working how do I solve this? 2ND problem is I have the following CSS: input:focus { background-color:yellow; } input[type="text"], input[type="date"],input[type="time"],input[type="number"],textarea,select { border-radius:5px; border-width: 1px; border-style: solid; border-color: #C6C6C6; height:41px; background-color: #FF3434; width: 100%; } But when the item is focused it doesn't change to yellow, if i remove "background-color: #FF3434;" it turns yellow on focus? Is what I am doing not able to be done? Or am I going about this wrong? Thanks

  • Create Clone Without Effecting Results of Original Object

    I have a function that when selecting an option, returns results. I want to be able to clone that function and have the ability to return another set of results, without adding the new results to the original object. // shows / hides results based on selection $(".categories-select").live("change" ,function(){ if($(this).val() == 'red'){ $('.red').removeClass('hide'); // toggles red results, sub menus $(this).parent('.controls').find('.sub').removeClass('hide'); } if($(this).val() == 'blue'){ $('.blue').removeClass('hide'); $(this).parent('.controls').find('.sub').addClass('hide'); } if($(this).val() == 'purple'){ $('.purple').removeClass('hide'); $(this).parent('.controls').find('.sub').addClass('hide'); } if($(this).val() == 'orange'){ $('.orange').removeClass('hide'); $(this).parent('.controls').find('.sub').addClass('hide'); } }); // Duplicates category select menu $(".add-color").find(function(){ $(".color-category").clone().removeClass('color-category').appendTo("#we-want-to").find('.sub,').addClass('hide') ; }); $(".add-color-alternate").click(function(){ $(".color-category-alternate").clone().removeClass('color-category-alternate').appendTo("#we-want-to").find('.sub, .results-table').addClass('hide'); });

  • When destroying one record, another one gets destroyed

    - by normalocity
    Products (like an iPod Classic) :has_many = :listings, :dependent = :destroy Listings (like "My name is Joe, and I have an iPod for sale) :belongs_to = :product So, if I delete a given Product, all the listings that point to it get deleted. That makes sense, and is by design. However, I am writing a "merge" function, where you merge two Products into one, and combine their Listings. So, let's say my two products are "iPod Color" and "iPod Classic", and I want to merge the two. What I want to do is say, "iPod Color, merge into iPod Classic", and result should be that: All the iPod Color Listings are re-pointed to the iPod Classic product After the product_id change, the Listing(s) are saved I then delete the "iPod Color" product Well, that should all work fine, without deleting any Listings. However, I've got this controller, and for whatever reason when I destroy the "iPod Color" Product, even after confirming that the Listings have been moved to "iPod Classic" and saved to the database, the Listings that were previously pointed to "iPod Color" get destroyed as well, and I can't figure out why. It's as if they are retaining some kind of link to the destroyed product, and therefore begin destroyed themselves. What painfully obvious thing am I missing? def merge merging_from = Product.find(params[:id]) merging_to = Product.find_by_model(params[:merging_to]) unless merging_to.nil? unless merging_from.nil? unless merging_from == merging_to # you don't want to merge something with itself merging_from.listings.each do |l| l.product = merging_to l.save end # through some debugging, I've confirmed that my missing Listings are disappearing as a result of the following destroy call merging_from.destroy end end end

  • Handling multiple media queries in Sass with Twitter Bootstrap

    - by Keith
    I have a Sass mixin for my media queries based on Twitter Bootstrap's responsive media queries: @mixin respond-to($media) { @if $media == handhelds { /* Landscape phones and down */ @media (max-width: 480px) { @content; } } @else if $media == small { /* Landscape phone to portrait tablet */ @media (max-width: 767px) {@content; } } @else if $media == medium { /* Portrait tablet to landscape and desktop */ @media (min-width: 768px) and (max-width: 979px) { @content; } } @else if $media == large { /* Large desktop */ @media (min-width: 1200px) { @content; } } @else { @media only screen and (max-width: #{$media}px) { @content; } } } And I call them throughout my SCSS file like so: .link { color:blue; @include respond-to(medium) { color: red; } } However, sometimes I want to style multiple queries with the same styles. Right now I'm doing them like this: .link { color:blue; /* this is fine for handheld and small sizes*/ /*now I want to change the styles that are cascading to medium and large*/ @include respond-to(medium) { color: red; } @include respond-to(large) { color: red; } } but I'm repeating code so I'm wondering if there is a more concise way to write it so I can target multiple queries. Something like this so I don't need to repeat my code (I know this doesn't work): @include respond-to(medium, large) { color: red; } Any suggestions on the best way to handle this?

  • Adding a ActionPerformed Array to a String Array

    - by user267490
    Hey, Before you guys ask, yes I've searched online for the answer, but everything I found just leaves a lil confuse and nothing is recent so asking in those forums won't really help. My problems is this: I have an array that holds my name for a menu. String[] fontColor = new String[] {"Red", "Blue", "Green"}; for (int i = 0; i < fontColors.length; i++) { JMenuItem fontC = new JMenuItem(fontColors[i]); fontC.addActionListener(new fontColorAction()); changeFontColor.add(fontC); } Then I have an array that holds my color change in a class called fontColorAction in that class I have another array that does the same thing as my string array except all thats in the statement is textarea.setForeground(colorArr[i]); that will set the setForeground() in order, but now how do I successfully attact the action listner in my class to my menuItems? my class looks like this private class fontColorAction implements ActionListener { Color[] colorArr - new Color[] {"Color.RED","Color.BLUE","Color.GREEN"}; public void actionPerformed(ActionEvent e){ for(i = 0; i < collorArr.length; i++){ textarea.setForeground(colorArr[i]); } } }

  • XmlSerializer construction with same named extra types

    - by NoizWaves
    Hey, I am hitting trouble constructing an XmlSerializer where the extra types contains types with the same Name (but unique Fullname). Below is an example that illustrated my scenario. Type definitions in external assembly I cannot manipulate: public static class Wheel { public enum Status { Stopped, Spinning } } public static class Engine { public enum Status { Idle, Full } } Class I have written and have control over: public class Car { public Wheel.Status WheelStatus; public Engine.Status EngineStatus; public static string Serialize(Car car) { var xs = new XmlSerializer(typeof(Car), new[] {typeof(Wheel.Status),typeof(Engine.Status)}); var output = new StringBuilder(); using (var sw = new StringWriter(output)) xs.Serialize(sw, car); return output.ToString(); } } The XmlSerializer constructor throws a System.InvalidOperationException with Message "There was an error reflecting type 'Engine.Status'" This exception has an InnerException of type System.InvalidOperationException and with Message "Types 'Wheel.Status' and 'Engine.Status' both use the XML type name, 'Status', from namespace ''. Use XML attributes to specify a unique XML name and/or namespace for the type." Given that I am unable to alter the enum types, how can I construct an XmlSerializer that will serialize Car successfully?

  • CSS refuse to obey

    Hi, I'll make this short, I got this webpage : <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link rel="Stylesheet" type="text/css" href="css/style.css" /> <link rel="Stylesheet" type="text/css" href="css/nav.css" /> </head> <body> <div id="header"> <ul id="navList"> <li><a href="#" id="navActive">foo</a></li> <li><a href="#">bar</a></li> </ul> </div> </body> </html> With this CSS style.css body { padding:0; margin:0; background-color:#000000; background-repeat:no-repeat; background-image:url('../img/bg.jpg'); } nav.css #navList { padding:0; margin:0; background-image:url('../img/menu.png'); list-style-type:none; padding:12px 150px; } #navList li { display:inline; } #navList li a { color:#bfbfbf; padding:14px 25px; text-decoration:none; } #navList li a:hover { color:#000000; background-color:#bfbfbf; text-decoration:none; } #navActive { color:#000000; background-color:#bfbfbf; } It looks like the CSS from the navActive id is never being applied... Could someone tell me why and/or suggest me a way to correct this. Thanks.

  • GLSL point inside box test

    - by wcochran
    Below is a GLSL fragment shader that outputs a texel if the given texture coord is inside a box, otherwise a color is output. This just feels silly and the there must be a way to do this without branching? uniform sampler2D texUnit; varying vec4 color; varying vec2 texCoord; void main() { vec4 texel = texture2D(texUnit, texCoord); if (any(lessThan(texCoord, vec2(0.0, 0.0))) || any(greaterThan(texCoord, vec2(1.0, 1.0)))) gl_FragColor = color; else gl_FragColor = texel; } Below is a version without branching, but it still feels clumsy. What is the best practice for "texture coord clamping"? uniform sampler2D texUnit; varying vec4 color; varying vec4 labelColor; varying vec2 texCoord; void main() { vec4 texel = texture2D(texUnit, texCoord); bool outside = any(lessThan(texCoord, vec2(0.0, 0.0))) || any(greaterThan(texCoord, vec2(1.0, 1.0))); gl_FragColor = mix(texel*labelColor, color, vec4(outside,outside,outside,outside)); } I am clamping texels to the region with the label is -- the texture s & t coordinates will be between 0 and 1 in this case. Otherwise, I use a brown color where the label ain't. Note that I could also construct a branching version of the code that does not perform a texture lookup when it doesn't need to. Would this be faster than a non-branching version that always performed a texture lookup? Maybe time for some tests...

  • CSS H4 hover style

    - by user1750613
    I tried many css from other places and stackoverflow, but somehow I can not make it done. I'm very new to css, and using Joomla and a template. I'm using custom.css folder for certain customizations on style. Here is I want to do: I want to style h4 when it is a link. For example, I'm creating a custom html module, have a list in the content. And in the content I'm giving each, h5 style, and a link to it to a certain page in the site. What I want to achieve is to have this list with color blue. And when mouse over-hover to have underline and still the same color. And when clicked back to the original position with no underline and no color change. (the same color in every situation, just underline when you are over it.) I tried these h5, h5 a, h5 a: hover, h5 .contentheading a, and so on... In one instance, it was working with : h5 { font-family: arial, sans-serif; font-size: 1.3em; font-weight: bold; } h5 a { color: #0088CC; } h5 a: hover { color: #0088CC; text-decoration: underline; } As I read I should use 'a' when the heading is a link. But now something is overriding it, I'm completely lost now. I see a:hover style in the inspection. I want to use this h5 in several content (in custom modules) when I want to style a content as a list to links. And I thought it will be practical to have one heading with a certain style so that I can use it with flexibility. Thanks a lot, any help will be great : )

  • pass variable by reference within class? in php

    - by user151841
    I'm working on a hex color class where you can change the color values of any hex code color. In my example, I haven't finished the hex math, but it's not completely relevant to what I'm explaining here. Naively, I wanted to start to do something that I don't think can be done. I wanted to pass object properties in a method call. Is this possible? class rgb { private $r; private $b; private $g; public function __construct( $hexRgb ) { $this->r = substr($hexRgb, 0, 2 ); $this->g = substr($hexRgb, 2, 2 ); $this->b = substr($hexRgb, 4, 2 ); } private function add( & $color, $amount ) { $color += amount; // $color should be a class property, $this->r, etc. } public function addRed( $amount ) { self::add( $this->r, $amount ); } public function addGreen( $amount ) { self::add( $this->g, $amount ); } public function addBlue( $amount ) { self::add( $this->b, $amount ); } } If this is not possible in PHP, what is this called and in what languages is it possible? I know I could do something like public function add( $var, $amount ) { if ( $var == "r" ) { $this->r += $amount } else if ( $var == "g" ) { $this->g += $amount } ... } But I want to do it this cool way.

  • Changing Value of Array Pointer When Passed to a Function

    - by ZAX
    I have a function which receives both the array, and a specific instance of the array. I try to change the specific instance of the array by accessing one of its members "color", but it does not actually change it, as can be seen by debugging (checking the value of color after function runs in the main program). I am hoping someone can help me to access this member and change it. Essentially I need the instance of the array I'm specifying to be passed by reference if nothing else, but I'm hoping there is an easier way to accomplish what I'm trying to do. Here's the structures: typedef struct adjEdge{ int vertex; struct adjEdge *next; } adjEdge; typedef struct vertex{ int sink; int source; int color; //0 will be white, 1 will be grey, 5 will be black int number; adjEdge *nextVertex; } vertex; And here is the function: void walk(vertex *vertexArray, vertex v, int source, maxPairing *head) { int i; adjEdge *traverse; int moveVertex; int sink; traverse = vertexArray[v.number-1].nextVertex; if(v.color != 5 && v.sink == 5) { sink = v.number; v.color = 5; addMaxPair(head, source, sink); } else { walk(vertexArray, vertexArray[traverse->vertex-1], source, head); } } In particular, v.color needs to be changed to a 5, that way later after recursion the if condition blocks it.

  • How to implement efficient Fog of War?

    - by Cambrano
    I've asked a question how to implement Fog Of War(FOW) with shaders. Well I've got this working. I use the vertex color to identify the alpha of a single vertex. I guess the most of you know what the FOW of Age of Empires was like, anyway I'll shortly explain it: You have a map. Everything is unexplored(solid black / 100% transparency) at the beginning. When your NPC's / other game units explore the world (by moving around mostly) they unshadow the map. That means. Everything in a specific radius (viewrange) around a NPC is visible (0%transparency). Anything that is out of viewrange but already explored is visible but shadowed (50% transparency). So yeah, AoE had relatively huge maps. Requirements was something around 100mhz etc. So it should be relatively easy to implement something to solve this problem - actually. Okay. I'm currently adding planes above my world and set the color per vertex. Why do I use many planes ? Unity has a vertex limit of 65.000 per mesh. According to the size of my tiles and the size of my map I need more than one plane. So I actually need a lot of planes. This is obviously pita for my FPS. Well so my question is, what are simple (in sense of performance) techniques to implement a FOW shader? Okay some simplified code what I'm doin so far: // Setup for (int x = 0; x < (Map.Dimension/planeSize); x++) { for (int z = 0; z < (Map.Dimension/planeSize); z++) { CreateMeshAt(x*planeSize, 3, z*planeSize) } } // Explore (is called from NPCs when walking for example) for (int x = ((int) from.x - radius); x < from.x + radius; x ++) { for (int z = ((int) from.z - radius); z < from.z + radius; z ++) { if (from.Distance(x, 1, z) > radius) continue; _transparency[x/tileSize, z/tileSize] = 0.5f; } } // Update foreach(GameObject plane in planes){ foreach(Vector3 vertex in vertices){ Vector3 worldPos = GetWorldPos(vertex); vertex.Color = new Color(0,0,0, _transparency[worldPos.x/tileSize, worldPos.z/tileSize]); } } My shader just sets the transparency of the vertex now, which comes from the vertex color channel

  • Multi Pass Blend

    - by Kirk Patrick
    I am seeking the simplest working example of a two pass HLSL pixel shader. It can do anything really, but the main idea is to perform "ping ponging" to take the output of the first pass and then send it for the second pass. In my example I want to draw to the R channel and then draw to the G channel and produce a simple Venn Diagram in the shader, but need to detect overlap. I can currently detect one or the other but not overlap. There are a red and green circle overlapping, and I want to put a dynamic texture map in the overlap region. I can currently put it in either or. Below is how it looks in the shader. -------------------------------- Texture2D shaderTexture; SamplerState SampleType; ////////////// // TYPEDEFS // ////////////// struct PixelInputType { float4 position : SV_POSITION; float2 tex0 : TEXCOORD0; float2 tex1 : TEXCOORD1; float4 color : COLOR; }; //////////////////////////////////////////////////////////////////////////////// // Pixel Shader //////////////////////////////////////////////////////////////////////////////// float4 main(PixelInputType input) : SV_TARGET { float4 textureColor0; float4 textureColor1; // Sample the pixel color from the texture using the sampler at this texture coordinate location. textureColor0 = shaderTexture.Sample(SampleType, input.tex0); textureColor1 = shaderTexture.Sample(SampleType, input.tex1); if (input.color[0]==1.0f && input.color[1]==1.0f) // Requires multi-pass textureColor0 = textureColor1; return textureColor0; } Here is the calling code (that needs to be modified) m_d3dContext->IASetVertexBuffers(0, 2, vbs, strides, offsets); m_d3dContext->IASetIndexBuffer(m_indexBuffer.Get(), DXGI_FORMAT_R32_UINT,0); m_d3dContext->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST); m_d3dContext->IASetInputLayout(m_inputLayout.Get()); m_d3dContext->VSSetShader(m_vertexShader.Get(), nullptr, 0); m_d3dContext->VSSetConstantBuffers(0, 1, m_constantBuffer.GetAddressOf()); m_d3dContext->PSSetShader(m_pixelShader.Get(), nullptr, 0); m_d3dContext->PSSetShaderResources(0, 1, m_SRV.GetAddressOf()); m_d3dContext->PSSetSamplers(0, 1, m_QuadsTexSamplerState.GetAddressOf());

  • problem with sIFR 3 not displaying in IE just getting XXX

    - by user288306
    I am having a problem with sIFR 3 not displaying in IE. I get 3 larges black XXX in IE yet it displays fine in Firefox. I have checked i do have the most recent version of flash installed correctly. Here is the code on the page <div id="features"> <div id="mainmessage_advertisers"><h2>Advertisers</h2><br /><br /><h3><a href="">Reach your customers where they browse. Buy directly from top web publishers.</a></h3><br /><br /><br /><a href=""><img src="img/buyads.gif" border="0"></a></div> <div id="mainmessage_publishers"><h2>Publishers</h2><br /><br /><h3>Take control of your ad space and start generating more revenue than <u>ever before</u>.</h3><br /><br /><br /><a href=""><img src="img/sellads.gif" border="0"></a></div> </div>` Here is the code from my

  • Node.js + Express.js. How to RENDER less css?

    - by Paden
    Hello all, I am unable to render less css in my express workspace. Here is my current configuration (my css/less files go in 'public/stylo/'): app.configure(function() { app.set('views' , __dirname + '/views' ); app.set('partials' , __dirname + '/views/partials'); app.set('view engine', 'jade' ); app.use(express.bodyDecoder() ); app.use(express.methodOverride()); app.use(express.compiler({ src: __dirname + '/public/stylo', enable: ['less']})); app.use(app.router); app.use(express.staticProvider(__dirname + '/public')); }); Here is my main.jade file: !!! html(lang="en") head title Yea a title link(rel="stylesheet", type="text/css", href="/stylo/main.less") link(rel="stylesheet", href="http://fonts.googleapis.com/cssfamily=Droid+Sans|Droid+Sans+Mono|Ubuntu|Droid+Serif") script(src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js") script(src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/jquery-ui.min.js") body!= body here is my main.less css: @import "goodies.css"; body { .googleFont; background-color : #000000; padding : 20px; margin : 0px; > .header { border-bottom : 1px solid #BBB; background-color : #f0f0f0; margin : -25px -25px 30px -25px; /* important */ color : #333; padding : 15px; font-size : 18pt; } } AND here is my goodies.less css: .rounded_corners(@radius: 10px) { -moz-border-radius : @radius; -webkit-border-radius: @radius; border-radius : @radius; } .shadows(@rad1: 0px, @rad2: 1px, @rad3: 3px, @color: #999) { -webkit-box-shadow : @rad1 @rad2 @rad3 @color; -moz-box-shadow : @rad1 @rad2 @rad3 @color; box-shadow : @rad1 @rad2 @rad3 @color; } .gradient (@type: linear, @pos1: left top, @pos2: left bottom, @color1: #f5f5f5, @color2: #ececec) { background-image : -webkit-gradient(@type, @pos1, @pos2, from(@color1), to(@color2)); background-image : -moz-linear-gradient(@color1, @color2); } .googleFont { font-family : 'Droid Serif'; } Cool deal. Now: I have installed less via npm and I had heard from another post that @imports should reference the .css not the .less. In any case, I have tried the combinations of switching .less for .css in the jade and less files with no success. If you can help or have the solution I'd greatly appreciate it. Note: The jade portion works fine if I enter any ol' .css. Note2: The less compiles if I use lessc via command line.

  • jquery css menu not selecting the active link

    - by Ronedog
    What is wrong with this and how could I fix it. I have css menu (horizontal) that I want the background and font to be changed when one of the items is selected. I found another post that gave me some jquery code to help make it work, and I thought I had it coded right, but when I click on an item to change its class it adds the class, but the background and font stay the same? Any ideas here? Heres the HTML <ul id="menu_nav" class="buttons"> <li> <a href="#" onclick="' . $menu_path . '">Item 1</a> </li> <li> <a href="#" onclick="' . $menu_path . '">Item 2</a> </li> <li> <a href="#" onclick="' . $menu_path . '">Item 3</a> </li> </ul> Heres the CSS: ul#menu_nav { float:left; width:790px; padding:0; margin:0; list-style-type:none; background-color:#000099; } ul#menu_nav a { float:left; text-decoration:none; color:white; background-color:#000099; padding:0.2em 0.6em; border-right:1px solid #CCCCCC; font-family: Tahoma; font-size: 11px; font-style: normal; font-weight: bold; position: relative; height: 21px; line-height:1.85em; } ul#menu_nav a:hover { background-color:#F1F4FE; color:#000099; border-top:1px solid #CCCCCC; } ul#menu_nav li {display:inline;} .selected { background-color:#F1F4FE; color:#000099; border-top:1px solid #CCCCCC; } Here's the Jquery: $(function(){ $(".buttons li>a").click(function(){ $(this).parent().addClass('selected'). // <li> siblings().removeClass('selected'); }); });

  • Avoiding Redundancies in XML documents

    - by MarceloRamires
    I was working with a certain XML where there were no redundancies <person> <eye> <eye_info> <eye_color> blue </eye_color> </eye_info> </eye> <hair> <hair_info> <hair_color> blue </hair_color> </hair_info> </hair> </person> As you can see, the sub-tag eye-color makes reference to eye in it's name, so there was no need to avoid redundancies, I could get the eye color in a single line after loading the XML into a dataset: dataset.ReadXml(path); value = dataset.Tables("eye_info").Rows(0)("eye_color"); I do realise it's not the smartest way of doing so, and this situation I'm having now wasn't unforeseen. Now, let's say I have to read xml's that are in this format: <person> <eye> <info> <color> blue </color> </info> </eye> <hair> <info> <color> blue </color> </info> </hair> </person> So If I try to call it like this: dataset.ReadXml(path); value = dataset.Tables("info").Rows(0)("color"); There will be a redundancy, because I could only go as far as one up level to identify a single field in a XML with my previous method, and the 'disambiguator' is three levels above. Is there a practical way to reach with no mistake a single field given all the above (or at least a few) fields ?

  • Issue with angular gradient algorithm

    - by user146780
    I have an angular gradient algorithm: GLuint OGLENGINEFUNCTIONS::CreateAngularGradient( std::vector<ARGBCOLORF> &input,POINTFLOAT start, POINTFLOAT end, int width, int height ) { std::vector<GLubyte> pdata(width * height * 4); float pi = 3.1415; float cx; float cy; float r1; float r2; float ang; float px; float py; float t; cx = start.x; cy = start.y; r1 = 0; r2 = 500; ang = end.x / 100; ARGBCOLORF color; for (unsigned int i = 0; i < height; i++) { for (unsigned int j = 0; j < width; j++) { px = j; py = i; if( px * px + py * py <= r2 * r2 && px * px + py * py >= r1 * r1 ) { t= atan2(py-cy,px-cx) + ang; t= t+ pi; if (t > 2* pi) { t=t-2*pi; t=t/(2*pi); } } //end + start color.r = (0 * t) + (120 * (1 - t)); color.g = (50 * t) + (255 * (1 - t)); color.b = (0 * t) + (50 * (1 - t)); color.a = (255 * t) + (200 * (1 - t)); pdata[i * 4 * width + j * 4 + 0] = (GLubyte) color.r; pdata[i * 4 * width + j * 4 + 1] = (GLubyte) color.g; pdata[i * 4 * width + j * 4 + 2] = (GLubyte) 12; pdata[i * 4 * width + j * 4 + 3] = (GLubyte) 255; } } It works fine except the ang variable only controls the end sweep, not the start sweep. The start sweep is always facing the middle left as seen here: http://img810.imageshack.us/img810/9623/uhoh.png Basically I have no control over the end one going this <- way. How could I control this one? Thanks
