  • Hit detection on non-transparent pixel

    - by Abie
    Given a PNG in a web context with some transparent pixels and some non-transparent pixels, is there a way in Javascript to determine if a user has clicked on a non-transparent pixel? A webkit-only solution would be perfectly acceptable.

  • Manipulating pixels using only toDataURL

    - by Chris
    The problem I have is this: I need to be able to dynamically tint an image using Javascript, but I cannot access pixel data via the canvas. I can, however, store the dataURL (or any other text-based data format) and include that with the code, manipulate that data, and then create an image object using that dataURL. My question is, how can I access the RGBA value of each pixel, given only the dataURL. I assume I need to decode the base64 url, but into what format in order to manipulate on the pixel level? And then would be it be as trivial as re-encoding it as base64, slapping it in a url, and the passing to an image? Thanks.

  • Programmatically swap colors from a loaded bitmap to Red, Green, Blue or Gray, pixel by pixel.

    - by eyeClaxton
    Download source code here: http://www.eyeClaxton.com/download/delphi/ColorSwap.zip I would like to take a original bitmap (light blue) and change the colors (Pixel by Pixel) to the red, green, blue and gray equivalence relation. To get an idea of what I mean, I have include the source code and a screen shot. Any help would be greatly appreciated. If more information is needed, please feel free to ask. If you could take a look at the code below, I have three functions that I'm looking for help on. The functions "RGBToRed, RGBToGreen and RGBToRed" I can't seem to come up with the right formulas. unit MainUnit; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, ExtCtrls, StdCtrls; type TMainFrm = class(TForm) Panel1: TPanel; Label1: TLabel; Panel2: TPanel; Label2: TLabel; Button1: TButton; BeforeImage1: TImage; AfterImage1: TImage; RadioGroup1: TRadioGroup; procedure FormCreate(Sender: TObject); procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } end; var MainFrm: TMainFrm; implementation {$R *.DFM} function RGBToGray(RGBColor: TColor): TColor; var Gray: Byte; begin Gray := Round( (0.90 * GetRValue(RGBColor)) + (0.88 * GetGValue(RGBColor)) + (0.33 * GetBValue(RGBColor))); Result := RGB(Gray, Gray, Gray); end; function RGBToRed(RGBColor: TColor): TColor; var Red: Byte; begin // Not sure of the algorithm for this color Result := RGB(Red, Red, Red); end; function RGBToGreen(RGBColor: TColor): TColor; var Green: Byte; begin // Not sure of the algorithm for this color Result := RGB(Green, Green, Green); end; function RGBToBlue(RGBColor: TColor): TColor; var Blue: Byte; begin // Not sure of the algorithm for this color Result := RGB(Blue, Blue, Blue); end; procedure TMainFrm.FormCreate(Sender: TObject); begin BeforeImage1.Picture.LoadFromFile('Images\RightCenter.bmp'); end; procedure TMainFrm.Button1Click(Sender: TObject); var Bitmap: TBitmap; I, X: Integer; Color: Integer; begin Bitmap := TBitmap.Create; try Bitmap.LoadFromFile('Images\RightCenter.bmp'); for X := 0 to Bitmap.Height do begin for I := 0 to Bitmap.Width do begin Color := ColorToRGB(Bitmap.Canvas.Pixels[I, X]); case Color of $00000000: ; // Skip any Color Here! else case RadioGroup1.ItemIndex of 0: Bitmap.Canvas.Pixels[I, X] := RGBToBlue(Color); 1: Bitmap.Canvas.Pixels[I, X] := RGBToRed(Color); 2: Bitmap.Canvas.Pixels[I, X] := RGBToGreen(Color); 3: Bitmap.Canvas.Pixels[I, X] := RGBToGray(Color); end; end; end; end; AfterImage1.Picture.Graphic := Bitmap; finally Bitmap.Free; end; end; end. Okay, I apologize for not making it clearer. I'm trying to take a bitmap (blue in color) and swap the blue pixels with another color. Like the shots below.

  • Where in a typical rendering pipeline does visibility and shading occur?

    - by user29163
    I am taking a computer graphics course. The book and the lecture notes are vague on the on the order of flow between the different steps in the rendering process. For example, if we have specified a view in a scene, and then want to perform a projection transformation for that given view, then we have to go through a sequence of transformations. In the end we end up with a normalized "viewcube" ready to be mapped 2D after clipping. But why do we end up with a cube (ie 3D thing), when a projection results in projecting the 3D objects to 2D. (depth information is lost?) The other line of reasoning is that all information further needed is stored within the "cube" and that visibility detection and shading is performed with respect to this cube and then we perform rasterezation.

  • underline line thickness always one pixel...

    - by Mark
    ...regardless of font size. Its an mx:Text object. (The Text object is actually being used as a mask so don't know if that's the problem.) If underline is set with the <u> tag in Text.htmlText, or Text.textField.setTextFormat, the underline thickness is always just one pixel which is not acceptable. (There are other problems with <u> so I'm limited to using setTextFormat currently.) Can the thickness of an underline be set through CSS? (textField.styleSheet, etc.) I may have another problem as I already use setTextFormat extensively, and the documentation says you can't use textField.setTextFormat if you use textField.setStyleSheet. I primarily need the underline to simulate correctly the look for an anchor tag.

  • Pan point on Google Map to specific pixel position on screen (API v3)

    - by Jake
    When overlay is a Google maps overlay and offsetx, offsety is the pixel distance from the maps center that I want to pan latlong to, the following works. var projection = overlay.getProjection(); var pxlocation = projection.fromLatLngToContainerPixel(latlong); map.panTo(projection.fromContainerPixelToLatLng(new google.maps.Point(pxlocation.x+offsetx,pxlocation.y+offsety))); However, I don't always have an overlay on the map and map.getProjection() returns a projection, not a MapCanvasProjection which does not have the methods I need. Is there a way to do this without making an overlay specificaly for it?

  • Finding specific pixel colors of a BitmapImage

    - by Andrew Shepherd
    I have a WPF BitmapImage which I loaded from a .JPG file, as follows: this.m_image1.Source = new BitmapImage(new Uri(path)); I want to query as to what the colour is at specific points. For example, what is the RGB value at pixel (65,32)? How do I go about this? I was taking this approach: ImageSource ims = m_image1.Source; BitmapImage bitmapImage = (BitmapImage)ims; int height = bitmapImage.PixelHeight; int width = bitmapImage.PixelWidth; int nStride = (bitmapImage.PixelWidth * bitmapImage.Format.BitsPerPixel + 7) / 8; byte[] pixelByteArray = new byte[bitmapImage.PixelHeight * nStride]; bitmapImage.CopyPixels(pixelByteArray, nStride, 0); Though I will confess there's a bit of monkey-see, monkey do going on with this code. Anyway, is there a straightforward way to process this array of bytes to convert to RGB values?

  • Encode complex number as RGB pixel and back

    - by Vi
    How is it better to encode a complex number into RGB pixel and vice versa? Probably (logarithm of) an absolute value goes to brightness and an argument goes to hue. Desaturated pixes should receive randomized argument in reverse transformation. Something like: 0 - (0,0,0) 1 - (255,0,0) -1 - (0,255,255) 0.5 - (128,0,0) i - (255,255,0) -i - (255,0,255) (0,0,0) - 0 (255,255,255) - e^(i * random) (128,128,128) - 0.5 * e^(i *random) (0,128,128) - -0.5 Are there ready-made formulas for that? Edit: Looks like I just need to convert RGB to HSB and back. Edit 2: Existing RGB - HSV converter fragment: if (hsv.sat == 0) { hsv.hue = 0; // ! return hsv; } I don't want 0. I want random. And not just if hsv.sat==0, but if it is lower that it should be ("should be" means maximum saturation, saturation that is after transformation from complex number).

  • How to read pixel values of a video?

    - by vikramtheone
    Hi Guys, I recently wrote C programs for image processing of BMP images, I had to read the pixel values and process them, it was very simple I followed the BMP header contents and I could get most of the information of the BMP image. Now the challenge is to process videos (Frame by Frame), how can I do it? How will I be able to read the headers of continuous streams of image frames in a video clip? Or else, is it like, for example, the mpeg format will also have universal header, upon reading which I can get the information about the entire video and after the header, all the data are only pixels. I hope I could convey. Has anyone got experience with processing videos? Any books or links to tutorials will be very helpful. Vikram

  • Calculating the pixel size of a string with Python

    - by Aristide
    I have a Python script which needs to calculate the exact size of arbitrary strings displayed in arbitrary fonts in order to generate simple diagrams. I can easily do it with Tkinter. The problem is the results seem to depend on the version of Python and/or the system. import Tkinter as tk import tkFont root = tk.Tk() times12 = tkFont.Font(family="times",size=12) print times12.metrics("linespace"), print times12.measure("Hello world") times24 = tkFont.Font(family="times",size=24) print times24.metrics("linespace"), print times24.measure("Hello world") Python 2.5 on Mac OS X gives the actual pixel measurements: 12 57 24 116 Python 2.6.1 on Mac OS X gives: 14 58 27 115 Python 2.6.3 on Windows XP gives: 19 71 36 154 Such a need being quite common, I suspect I did something wrong. Any idea?

    What is a simple pixel shader script effect to apply brightness and contrast? I found this one, but it doesn't seem to be correct: sampler2D input : register(s0); float brightness : register(c0); float contrast : register(c1); float4 main(float2 uv : TEXCOORD) : COLOR { float4 color = tex2D(input, uv); float4 result = color; result = color + brightness; result = result * (1.0+contrast)/1.0; return result; } thanks!

  • Wanting a type of grid for a pixel editor

    - by wiggles
    Hi, I am currently trying to develop a basic pixel editor application to build up my programming experience with Java. I am designing it so the user has several colour options on, they click on an option and then they can drag over the cells in the grid and they change colour (like a typical image editor, but with a sort of snap on to each grid cell) Any idea of what Java component, if any, is able to implement this type of grid in Java? I had thought of each cell being a JButton, but this seemed terribly inefficient and I don't think it would be possible to change the colour of each cell(button) with out individually clicking on each one. Any help appreciated.

  • Applying a pixel shader effect to a portion of an image

    - by Nick
    I have a ScrollViewer that contains a very large video (16 megapixel @ 10fps) and I want to apply a pixel shader effect to it. Given the size of the images I can't apply the effect directly to the image. So I apply the effect to the ScrollContentPresenter in the control style. Which is great, everything runs nice and fast. However, I'm also rendering annotations inside of the ScrollContentPresenter which I do NOT want effects applied to (but they need to move and scale along with the image). Is there to apply the effect just to the clipped and displayed portion of the image or do I need to build a rather more complex control?

  • How to efficiently deal with a large amount of HTML5 canvas pixel data over websockets

    - by user730569
    Using imageData = context.getImageData(0, 0, width, height); JSON.stringify(imageData.data); I grab the pixel data, convert it to a string, and then send it over the wire via websockets. However, this string can be pretty large, depending on the size of the canvas object. I tried using the compression technique found here: JavaScript implementation of Gzip but socket.io throws the error Websocket message contains invalid character(s). Is there an effective way to compress this data so that it can be sent over websockets?

  • Is Android (read typical devices) fast enough for a game that requires plotting pixel by pixel rather than blitting

    - by mP
    i have an idea for an Android game which is a little different from the typical game that usually moves sprites(bitmaps) around the screen. Id want to plot lots of little pixels to create my visuals. PROS no bitmaps required pixel plotting of stuff like "fire" can react to wind. no need to scale bitmaps, works w/ any screen res (lets pretend device can handle more drawing because its got a bigger screen). CONS slower to plot pixels than blit bitmaps need lot of animation frames. WISHES id like to update my game in real time, more is better 30fps is good but not essential, 15fps is enough. PERFORMANCE Q... Is the typical Android device fast enough to plot say half a screenful of pixels w/ a default background ? if full screen is not practical what window size should be able to handle such refreshes

  • Converting between square and rectangular pixel co-ordinates

    - by FlyboyUtah
    I'm new at using transforms and this type of math, and would appreciate some direction solving my coding problem. I'm writing in XCode for the iphone, and am working with CGraphics. Problem: In Xcode, I want to draw curves, lines and so on it's screen of of square pixels. Then convert those points, as close as possible, into non-square pixel sysem. For example if the original coordinate system is 500 x 500 pixels that are displayed on square screen of 10 by 10 inchs I draw a round circle with the circle formula. It looks round, and all is well. Now, I draw the same circle on a second 10 x 10 inch screen that is 850 pixels by 500 pixels. Without changing the coordinates, the same circle formual displays something that looks like an egg. How can I draw the circle on the second screen in a different coordinate system? And in addition, I need to access the set of points x,y system individually. s

Increasingly, DRM is also being utilized by Oracle customers for reference data management, an emerging solution space that deserves some explanation. What is reference data? Reference data is a close cousin of master data. While master data may be more rapidly changing, requires consensus building across stakeholders and lends structure to business transactions, reference data is simpler, more slowly changing, but has semantic content that is used to categorize or group other information assets – including master data – and give them contextual value. The following table contains an illustrative list of examples of reference data by type. Reference data types may include types and codes, business taxonomies, complex relationships & cross-domain mappings or standards. Types & Codes Taxonomies Relationships / Mappings Standards Transaction Codes Industry Classification Categories and Codes, e.g., North America Industry Classification System (NAICS) Product / Segment; Product / Geo Calendars (e.g., Gregorian, Fiscal, Manufacturing, Retail, ISO8601) Lookup Tables (e.g., Gender, Marital Status, etc.) Product Categories City à State à Postal Codes Currency Codes (e.g., ISO) Status Codes Sales Territories (e.g., Geo, Industry Verticals, Named Accounts, Federal/State/Local/Defense) Customer / Market Segment; Business Unit / Channel Country Codes (e.g., ISO 3166, UN) Role Codes Market Segments Country Codes / Currency Codes / Financial Accounts Date/Time, Time Zones (e.g., ISO 8601) Domain Values Universal Standard Products and Services Classification (UNSPSC), eCl@ss International Classification of Diseases (ICD) e.g., ICD9 à IC10 mappings Tax Rates Why manage reference data? Reference data carries contextual value and meaning and therefore its use can drive business logic that helps execute a business process, create a desired application behavior or provide meaningful segmentation to analyze transaction data. Further, mapping reference data often requires human judgment. Sample Use Cases of Reference Data Management Healthcare: Diagnostic Codes The reference data challenges in the healthcare industry offer a case in point. Part of being HIPAA compliant requires medical practitioners to transition diagnosis codes from ICD-9 to ICD-10, a medical coding scheme used to classify diseases, signs and symptoms, causes, etc. The transition to ICD-10 has a significant impact on business processes, procedures, contracts, and IT systems. Since both code sets ICD-9 and ICD-10 offer diagnosis codes of very different levels of granularity, human judgment is required to map ICD-9 codes to ICD-10. The process requires collaboration and consensus building among stakeholders much in the same way as does master data management. Moreover, to build reports to understand utilization, frequency and quality of diagnoses, medical practitioners may need to “cross-walk” mappings -- either forward to ICD-10 or backwards to ICD-9 depending upon the reporting time horizon. Spend Management: Product, Service & Supplier Codes Similarly, as an enterprise looks to rationalize suppliers and leverage their spend, conforming supplier codes, as well as product and service codes requires supporting multiple classification schemes that may include industry standards (e.g., UNSPSC, eCl@ss) or enterprise taxonomies. Aberdeen Group estimates that 90% of companies rely on spreadsheets and manual reviews to aggregate, classify and analyze spend data, and that data management activities account for 12-15% of the sourcing cycle and consume 30-50% of a commodity manager’s time. Creating a common map across the extended enterprise to rationalize codes across procurement, accounts payable, general ledger, credit card, procurement card (P-card) as well as ACH and bank systems can cut sourcing costs, improve compliance, lower inventory stock, and free up talent to focus on value added tasks. Specialty Finance: Point of Sales Transaction Codes and Product Codes In the specialty finance industry, enterprises are confronted with usury laws – governed at the state and local level – that regulate financial product innovation as it relates to consumer loans, check cashing and pawn lending. To comply, it is important to demonstrate that transactions booked at the point of sale are posted against valid product codes that were on offer at the time of booking the sale. Since new products are being released at a steady stream, it is important to ensure timely and accurate mapping of point-of-sale transaction codes with the appropriate product and GL codes to comply with the changing regulations. Multi-National Companies: Industry Classification Schemes As companies grow and expand across geographies, a typical challenge they encounter with reference data represents reconciling various versions of industry classification schemes in use across nations. While the United States, Mexico and Canada conform to the North American Industry Classification System (NAICS) standard, European Union countries choose different variants of the NACE industry classification scheme. Multi-national companies must manage the individual national NACE schemes and reconcile the differences across countries. Enterprises must invest in a reference data change management application to address the challenge of distributing reference data changes to downstream applications and assess which applications were impacted by a given change.

Example 20 20 pixels to upper left corner). private void DrawGrid() { LayoutRoot.Children.Clear(); Rectangle r = new Rectangle(); r.Width = 20; r.Height = 20; r.Fill = new SolidColorBrush(Color.FromArgb(255, 0, 255, 0)); r.Stroke = new SolidColorBrush(Color.FromArgb(255, 0, 255, 0)); r.SetValue(Canvas.LeftProperty, (double)0); r.SetValue(Canvas.TopProperty, (double)0); LayoutRoot.Children.Add(r); Color GridColor = Color.FromArgb(0xFF, 0x00, 0x00, 0x00); for (int y = 0; y < 11; y++) { Line l = new Line(); l.X1 = 0; l.Y1 = 30 * y - 1; l.X2 = 20 * 30; l.Y2 = 30 * y - 1; l.Stroke = new SolidColorBrush(GridColor); l.StrokeThickness = 1; LayoutRoot.Children.Add(l); } for (int x = 0; x < 21; x++) { Line l = new Line(); l.X1 = 30 * x; l.Y1 = 0; l.X2 = 30 * x; l.Y2 = 10 * 30; l.Stroke = new SolidColorBrush(GridColor); l.StrokeThickness = 1; LayoutRoot.Children.Add(l); } }

  • Internet Explorer table 1 pixel spacing problem

    - by Dennis G.
    I've found a strange problem with Internet Explorer related to table spacing and cannot find a way to work around it. An empty table results in a single pixel white space with Internet Explorer (6 and 7, 8 not yet tested), while all other browsers ignore the empty table. Here's a picture of the problem: And here is the minimum HTML code to reproduce the issue (please note that there are more margin/padding css attributes and table attributes specified than really needed, I just tested if this fixes IE's behavior): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <body> <div style="width: 200px; border: 1px black solid"> <table border="0" cellspacing="0" cellpadding="0" style="margin: 0pt; padding: 0pt; border-collapse: collapse;"> <tr> <td style="padding: 0; margin: 0"> </td> </tr> </table> <div style="background: red"> Test </div> </div> </body> </html> I'm not using an empty table as specified in the example above, but this was the minimum code that displays this behavior. Any ideas on how to fix this and remove the white space with IE?

  • Enumerating pixel formats for adaptors and modes with OpenGL

    - by Robinson
    I'm trying to code an OpenGL path for my 3D engine. The D3D path enumerates all device adaptors, all modes (by mode I mean bit depth, dimensions, available windowed, and refresh rate) for each adaptor and then all pixel formats available for the given mode and adaptor, along side certain useful caps (shader version, filter types, etc.). So, I have broadly got the following protected functions in the class: // Enumerate all back/front buffer combinations. virtual void EnumerateBackFrontBufferCombinations(CComPtr<IDirect3D9>& d3d9); // Enumerate all depth/stencil formats. virtual void EnumerateDepthStencilFormats(CComPtr<IDirect3D9>& d3d9); // Enumerate all multi-sample formats. virtual void EnumerateMultiSampleTypes(CComPtr<IDirect3D9>& d3d9); // Enumerate all device formats, i.e. dynamic, static, render target, etc. virtual void EnumerateMapFormats(CComPtr<IDirect3D9>& d3d9); // Enumerate all capabilities. virtual void EnumerateCapabilities(CComPtr<IDirect3D9>& d3d9); The adaptors are enumerated with EnumDisplayDevices, the modes (resolutions and refresh rates) are enumerated with EnumDisplaySettings, so this can be done for either GL or D3D. The other functions I'm not so sure about with OpenGL. What are the equivalents to the IDirect3D9's CheckDeviceType, CheckDeviceFormat, CheckDeviceMultiSampleType, CheckDepthStencilMatch? I know I can use DescribePixelFormat, given a DC, but you kind-of need to have created the window before you can use a DC with it, but you can't create the window correctly until you know what formats you're going to use. Any tips you can give me? Thanks.

  • HLSL, Program pixel shader with different Texture2D downscaling algorithms

    - by Kaminari
    I'm trying to port some image interpolation algorithms into HLSL code, for now i got: float2 texSize; float scale; int method; sampler TextureSampler : register(s0); float4 PixelShader(float4 color : COLOR0, float2 texCoord : TEXCOORD0) : COLOR0 { float2 newTexSize = texSize * scale; float4 tex2; if(texCoord[0] * texSize[0] > newTexSize[0] || texCoord[1] * texSize[1] > newTexSize[1]) { tex2 = float4( 0, 0, 0, 0 ); } else { if (method == 0) { tex2 = tex2D(TextureSampler, float2(texCoord[0]/scale, texCoord[1]/scale)); } else { float2 step = float2(1/texSize[0], 1/texSize[1]); float4 px1 = tex2D(TextureSampler, float2(texCoord[0]/scale-step[0], texCoord[1]/scale-step[1])); float4 px2 = tex2D(TextureSampler, float2(texCoord[0]/scale , texCoord[1]/scale-step[1])); float4 px3 = tex2D(TextureSampler, float2(texCoord[0]/scale+step[0], texCoord[1]/scale-step[1])); float4 px4 = tex2D(TextureSampler, float2(texCoord[0]/scale-step[0], texCoord[1]/scale )); float4 px5 = tex2D(TextureSampler, float2(texCoord[0]/scale+step[0], texCoord[1]/scale )); float4 px6 = tex2D(TextureSampler, float2(texCoord[0]/scale-step[0], texCoord[1]/scale+step[1])); float4 px7 = tex2D(TextureSampler, float2(texCoord[0]/scale , texCoord[1]/scale+step[1])); float4 px8 = tex2D(TextureSampler, float2(texCoord[0]/scale+step[0], texCoord[1]/scale+step[1])); tex2 = (px1+px2+px3+px4+px5+px6+px7+px8)/8; tex2.a = 1; } } return tex2; } technique Resample { pass Pass1 { PixelShader = compile ps_2_0 PixelShader(); } } The problem is that programming pixel shader requires different approach because we don't have the control of current position, only the 'inner' part of actual loop through pixels. I've been googling for about whole day and found none open source library with scaling algoriths used in loop. Is there such library from wich i could port some methods? I found http://www.codeproject.com/KB/GDI-plus/imgresizoutperfgdiplus.aspx but I really don't understand His approach to the problem, and porting it will be a pain in the ... Wikipedia tells a matematic approach. So my question is: Where can I find easy-to-port graphic open source library wich includes simple scaling algorithms? Of course if such library even exists :)
