  • Default.png images and iPad.

    - by Leg10n
    I'm about to submit my first iPad app, and I have 2 questions regarding to Default.png images. I would prefer a "splash screen" showing some artwork of my app, instead of the UI as if it was loaded, the app is a bit heavy and I've seen the users dispair when the UI is apparently loaded but it's not working. Does anyone know if apple is accepting apps with "splash screens"? I want to provide a Default-X.png for every orientation, I've read the iPad programming guide, my question is, is "Default-LandscapeLeft" a Default image rotated 90 degrees clockwise, and "Default-LandscapeRight" rotated 90 degrees counter clockwise? I'm asking this because I don't have an iPad yet to test this on. Thank you a lot in advance.

  • SDL/Pygame failing to load PNG images with cx_Freeze

    - by jjackson
    I'm running Python 3.1 on Windows and I'm trying to distribute my Pygame script as an executable via cx_Freeze. Right now it seems to be working except that the exe build can't load any of my images: Cannot load image: C:\path\to\build\exe.win32-3.1\resources\image.png File is not a Windows BMP file Googling has revealed that this happens when the SDL imaging library doesn't get included correctly. However, SDL_image.dll and libpng12-0.dll are both put by cx_Freeze into my build directory, so it seems to me like everything should be fine. Why wouldn't it be able to load PNG images?

  • Text to a PNG on App Engine (Python)

    - by Bemmu
    Note: I am cross-posting this from App Engine group because I got no answers there. As part of my site about Japan, I have a feature where the user can get a large PNG for use as desktop background that shows the user's name in Japanese. After switching my site hosting entirely to App Engine, I removed this particular feature because I could not find any way to render text to a PNG using the image API. In other words, how would you go about outputting an unicode string on top of an image of known dimensions (1024x768 for example), so that the text will be as large as possible horizontally, and centered vertically? Is there a way to do this is App Engine, or is there some external service besides App Engine that could make this easier for me, that you could recommend (besides running ImageMagick on your own server)?

  • Copy Small Bitmaps on to Large Bitmap with Transparency Blend: What is faster than graphics.DrawImag

    - by Glenn
    I have identified this call as a bottleneck in a high pressure function. graphics.DrawImage(smallBitmap, x , y); Is there a faster way to blend small semi transparent bitmaps into a larger semi transparent one? Example Usage: XY[] locations = GetLocs(); Bitmap[] bitmaps = GetBmps(); //small images sizes vary approx 30px x 30px using (Bitmap large = new Bitmap(500, 500, PixelFormat.Format32bppPArgb)) using (Graphics largeGraphics = Graphics.FromImage(large)) { for(var i=0; i < largeNumber; i++) { //this is the bottleneck largeGraphics.DrawImage(bitmaps[i], locations[i].x , locations[i].y); } } var done = new MemoryStream(); large.Save(done, ImageFormat.Png); done.Position = 0; return (done); The DrawImage calls take a small 32bppPArgb bitmaps and copies them into a larger bitmap at locations that vary and the small bitmaps might only partially overlap the larger bitmaps visible area. Both images have semi transparent contents that get blended by DrawImage in a way that is important to the output. I've done some testing with BitBlt but not seen significant speed improvement and the alpha blending didn't come out the same in my tests. I'm open to just about any method including a better call to bitblt or unsafe c# code.

  • Android map overly transparency has unwanted gradient

    - by DavidP2190
    I'm a making my first android app and for part of it I need some shaded areas over a mapview. I've got this working so far but the when I set the alpha of the fill colour, it goes strange. I'm not allowed to post images yet, but you can see what happens here: http://i.imgur.com/leXmc.png I'm not sure what causes it, but here is some code from where it gets drawn. public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) { Paint paint = new Paint(); paint.setStrokeWidth(2); paint.setColor(android.graphics.Color.GREEN); paint.setStyle(Paint.Style.FILL_AND_STROKE); paint.setAlpha(25); screenPoints = new Point[10]; Path path = new Path(); for (int x = 0; x<greenZone.length; x++){ screenPoints[x] = new Point(); mapView.getProjection().toPixels(greenZone[x], screenPoints[x]); } path.moveTo(screenPoints[0].x, screenPoints[0].y); for (int x = 1; x < screenPoints.length-1; x++){ paint.setAlpha(25); if (x<9){ path.lineTo(screenPoints[x].x, screenPoints[x].y); canvas.drawPath(path, paint); } else{ path.moveTo(screenPoints[screenPoints.length-1].x, screenPoints[screenPoints.length-1].y); path.lineTo(screenPoints[0].x, screenPoints[0].y); canvas.drawPath(path, paint); } } return true; } Thanks.

  • php png image transparency

    - by user1334130
    I have been working with some code to draw a circle but I am having problems with removing the black background from the shape. I am using imagecopyresampled for its AA features in order to draw a smooth circle, so I can't use a different drawing function. Thanks. <?php $img_2 = imagecreatetruecolor(200, 200); $red = imagecolorallocate($img_2, 255, 0, 0); imagefill($img_2, 0, 0, $red); //set circle values $xPos = 50; $yPos = 80; $diameter = 40; $img_1 = imagecreatetruecolor(($diameter + 2) * 2, ($diameter + 2) * 2); $green = imagecolorallocate($img_1, 0, 255, 0); //draw the circle imagefilledarc($img_1, $diameter+1, $diameter+1, ($diameter + 2) * 2, ($diameter + 2) * 2, 0, 360, $green, IMG_ARC_PIE); imagecopyresampled($img_2, $img_1, $xPos, $yPos, 0, 0, $diameter+2, $diameter+2, ($diameter + 2) * 2, ($diameter + 2) * 2); header("Content-type: image/png"); imagepng($img_2); imagedestroy($img_1); imagedestroy($img_2); ?>

  • cocos2d - how to draw a bottle sprite with dynamically changing water level

    - by Oliver
    I am trying to draw a (2d) sprite in cocos2d showing a bottle. The bottle shall be able to have a dynamic water level (i.e. the amount of water in the bottle can change over the lifetime of the sprite). I am wondering how to do this. I currently have a PNG file of the empty bottle. I adjusted the alpha channel of that PNG so when rendering the sprite I can draw a blue rectangle and render the bottle texture over it. That will give the impression of the water being inside the bottle. However, the bottle's shape is not a rectangle itself of course, so the water can be seen out of the bounds of the bottle. I can change the bottle image in a way that only the bottle itself is transparent and set the "outside world" to an opaque color & alpha channel value, but that again prevents the "world background" to be visible in that area. I simply don't have a clue how to realize this in a sane manner. Do I really have to read every pixel of the bottle image, identify which pixel is "inside" of the bottle and then draw the water pixel by pixel? There must be an easier way, right? ;) Any best practices for these kinds of tasks? edit: see picture below, to make somewhat clearer, what I am talking about ;) http://i47.tinypic.com/10rqww0.png

  • How come transparency in textures appears as white in 3ds Max?

    - by rFactor
    I have downloaded a free tree palm model that came with textures and a preview image. In the preview image the tree looks fine, but when I have deployed the textures to my scene, the leaves look green plus white, where white is the transparency area. Is there something I need to know about transparent textures? Both in the view-port and in the renderer all transparency appears as white. What could it be? Edit: The model I was talking about is implemented with two JPGs. One is textured and the other one is black-white where white represents transparency and is applied to the material in the opacity channel/map. The transparency seems to work somewhat, but there are white borders around the leaves. I think it's because the opacity channel does not properly filter out all white colors for some reason. It also seems that changing the blur affects it, but setting it to 0 does not remove it though (and makes it jaggy).

  • Flash CS4 compiler Error 1120 when embedding pngs into class instance variables.

    - by theolagendijk
    I have a Flash CS4 (Flash 9 ActionScript 3.0) project that compiles and runs perfectly on my machine. However it is part of a big batch of fla's that I want to compile on another (faster) machine. When I copy the project (the fla and all actionscripts and assets files) to the faster machine, it's Flash CS4 compiler gives me compiler error 1120 "Access of undefined property ButtonPause_PauseNormal". The property "PauseNormal" is an embedded png. The PNG is available. No transcoder errors. Here's the ActionScript for class "ButtonPause"; package nl.platipus.NissanESM.buttons { import flash.display.*; import flash.events.*; public class ButtonPause extends Sprite { [Embed(source="../../../../player/pause.png")] private var PauseNormal:Class; [Embed(source="../../../../player/pause_mo.png")] private var PauseMouseOver:Class; private var stateNormal:Bitmap; private var stateMouseOver:Bitmap; public function ButtonPause() { stateNormal = new PauseNormal(); stateNormal.width = 29; stateNormal.height = 14; stateNormal.alpha = 1; addChild(stateNormal); stateMouseOver = new PauseMouseOver(); stateMouseOver.width = 29; stateMouseOver.height = 14; stateMouseOver.alpha = 0; addChild(stateMouseOver); width = 29; height = 14; addEventListener(MouseEvent.MOUSE_OVER, handleMouseOver); addEventListener(MouseEvent.MOUSE_OUT, handleMouseOut ); } private function handleMouseOver(evt:MouseEvent):void { stateNormal.alpha = 0; stateMouseOver.alpha = 1; } private function handleMouseOut(evt:MouseEvent):void { stateNormal.alpha = 1; stateMouseOver.alpha = 0; } } } (Both machines run the exact same Flash CS4 Profesional Version 10.0.2 installation and both have the exact same publish settings and ActionScript 3.0 settings.) What's going on?

  • Image Resizing: Poor jpeg quality and black PNG backgrounds

    - by azz0r
    Hello, I have two issues with my class, basically the quality of the jpeg images is quite poor, but I'm not sure if thats down to my ratio resizing. Ideally I'd like this class to be strict with image sizes and crop into them, but I cant get my head around it. My main issue is that pngs always have a black bg, does anyone have experience with this happening? <?php class OpenSource_ImageResize { function __construct($theFile, $toWhere, $mime, $extension, $newWidth, $newHeight) { if ($mime == NULL) { $mime = getimagesize($theFile); $mime = $mime['mime']; } if ($mime == 'image/jpeg') { $size = getimagesize($theFile); if ($size[0] > $newWidth || $size[1] > $newHeight) { $sourceImage = imagecreatefromjpeg($theFile); } else { return copy($theFile, $toWhere); throw new exception('Could not create jpeg'); return false; } } else if ($mime == 'image/png') { $size = getimagesize($theFile); if ($size[0] > $newWidth || $size[1] > $newHeight) { $sourceImage = imagecreatefrompng($theFile); } else { return copy($theFile, $toWhere); //throw new exception('Could not create png'); return false; } } else if ($mime == 'image/gif') { $size = getimagesize($theFile); if ($size[0] > $newWidth || $size[1] > $newHeight) { $sourceImage = imagecreatefromgif ($theFile); } else { return copy($theFile, $toWhere); //throw new exception('Could not create gif'); return false; } } else { throw new exception('Not a valid mime type'); return false; } $oldX = imageSX($sourceImage); $oldY = imageSY($sourceImage); if ($newWidth == NULL) { $thumbHeight = $newHeight; $thumbWidth = round($newHeight/($oldY/$oldX)); } else if ($oldX > $oldY) { $thumbWidth = $newWidth; $thumbHeight = $oldY * ($newHeight/$oldX); } if ($oldX < $oldY) { $thumbWidth = round($newHeight/($oldY/$oldX)); $thumbHeight = $newHeight; } if ($oldX == $oldY) { $thumbWidth = $newWidth; $thumbHeight = $newHeight; } if (!gd_info()) { $dstImage = ImageCreate($thumbWidth, $thumbHeight); imagecopyresized($dstImage, $sourceImage, 0, 0, 0, 0, $thumbWidth, $thumbHeight, $oldX, $oldY); } else { $dstImage = ImageCreateTrueColor($thumbWidth, $thumbHeight); imagecopyresampled($dstImage, $sourceImage, 0, 0, 0, 0, $thumbWidth, $thumbHeight, $oldX, $oldY); } if ($mime == 'image/png') { $xparent = imagecolorresolvealpha($dstImage, 255,2,240, 0) ; imagecolortransparent($dstImage,$xparent); imagealphablending($dstImage,true); imagepng($dstImage, $toWhere); } else if ($mime == 'image/jpeg') { imagejpeg($dstImage, $toWhere); } else if ($mime == 'image/gif') { imagegif ($dstImage, $toWhere); } imagedestroy($dstImage); imagedestroy($sourceImage); return true; } }

  • How to set up offline manifest for a web app to run in Safari in iOS?

    - by ahmd1
    I'm currently trying to set up an offline.manifest file for my web app to be used offline on an iOS device. For testing purposes I have a very simple HTML page that I'm trying to add to a home screen. I'm testing it on a live iPhone 4, but after the page is added to the home screen and I put the iPhone in the airplane mode and try to start my web app I get this error: "Turn Off Airplane Mode or Use Wi-Fi to Access Data" and then if I click OK I get: "Cannot Open Web App Name" "Web App Name could not be opened because it is not connected to the Internet" The following is added to the HTML file: <!DOCTYPE html> <html lang="en" manifest="scrts/offline.manifest"> and the offline.manifest is composed as such: CACHE MANIFEST ../pics/bkgnd_iphn_settings.png ../pics/mbl_btn_fb.png ../pics/mbl_btn_twt.png ../pics/icon_57_57_bg.png ../pics/icon_72_72_bg.png ../pics/icon_114_114_bg.png ../pics/icon_144_144_bg.png ../pics/splash_320_460_bg.png ../pics/splash_768_1004_bg.png ../pics/splash_1004_768_bg.png I got all instructions on composing it from here I also adjusted the .htaccess file to add this line: AddType text/cache-manifest .manifest Any idea what am I not doing right?

  • Help me to simplify my jQuery, it's growing huge and redundant!

    - by liquilife
    Hey all, I am no jQuery expert, but I'm learning. I'm using a bit (growing to a LOT) of jQuery to hide some images and show a single image when a thumb is clicked. While this bit of jQuery works, it's horribly inefficient but I am unsure of how to simplify this to something that works on more of a universal level. <script> $(document).ready(function () { // Changing the Materials $("a#shirtred").click(function () { $("#selectMaterials img").removeClass("visible"); $("img.selectShirtRed").addClass("visible"); }); $("a#shirtgrey").click(function () { $("#selectMaterials img").removeClass("visible"); $("img.selectShirtGrey").addClass("visible"); }); $("a#shirtgreen").click(function () { $("#selectMaterials img").removeClass("visible");

  • PDF to PNG Processor - Paperclip

    - by Josh Crowder
    I am trying to develop a system in which a user can upload a slideshow (pdf) and it'll export each slide as a png. After some digging around I came across a post on here that suggested using a processor. I've had a go, but I cant get the command to run, if it is running then I don't know what is happening because no errors are being shown. Any help would be appreciated! module Paperclip class Slides < Processor def initialize(file, options = {}, attachment = nill) super @file = file @instance = options[:instance] @current_format = File.extname(@file.path) @basename = File.basename(@file.path, @current_format) end def make dst = Tempfile.new( [ @basename, @format].compact.join(".")) dst.binmode command = <<-end_command -size 640x300 #{ File.expand_path(dst.path) } tester.png end_command begin success = Paperclip.run("convert", command.gsub(/\s+/, " "))) rescue PaperclipCommandLineError raise PaperclipError, "There was an error processing the thumbnail for #{@basename}" end end end end I think my problem is with the convert command... When I run that command by hand, it works but it doesn't give the details of each slide it just executes it. What I need to happen is once its made all the slides, pass back the data to a new model... or I know where all the slides are, but once I get to that point I'm not sure what todo.

  • Mod_rewrite with multiple variables

    - by Andrei
    Hello, I'm using a PHP script that dynamically generates transparent PNGs for use as CSS backgrounds from a query string that takes RGBa and HSLa values. The original script can be found here, I've only added HSLa support. Because background URLs with PHP query strings aren't very pretty, and because it seems to break the IE 6 transparent PNG hack, I thought of using mod_rewrite to allow the script to be called when a .png with this syntax is called : /assets/colors/h[0-360 value]_s[0-100 value]_l[0-100 value]_a[0-100 value].png which would be rewritten to : /assets/colors.php?h=[0-360 value]&s=[0-100 value]&l=[0-100 value]&a=[0-100 value] Here's the issues I'm encountering : passing multiple variables with mod_rewrite using an underscore as a delimiter I know this could be done by passing a single variable and then exploding it in the PHP script, however I would prefer it to be done by Apache. Thanks in advance and if anyone wants my HSLa enabled version of the script just ask. Anyway I recommend you check it out on it's author's website.

Did they manage to replace the Default image and put an animation instead or just load an animation in the ApplicationDidFinishLaunching Thanks,
