Can anyone give an example of a short program that draws in a display specifying the color pixel by pixel? (for example, drawing a gradient fro...
Hi This is the first time I have ever attempted to do something like this, and just using rectangle collision with CGRectIntersectsRect for my UIImageViews isn't good enough anymore. What is the absolute simplest/best way of achieving pixel collision? All I need is for the alpha pixels to not collide, right? Hope you can help, thank...
Is there a way to render pixel fonts correctly in Silverlight 4? Without breaking text into paths or some sort of manual rendering because the text is dependent on data binding. Tweaks with UseLayoutRounding and .5px positioning shifting don't work. ...
For my project, I have to read each pixel in an image, perform a math operation on each pixel, then display the results of the modified pixel in an updated image. For this example, I took the square root of each pixel. public void rootCalc(){//go through the rows and columns for(int x=grayscale_orig.getWidth()...
i am using putpixel operation on image (srcImage) which is w = 134 and h = 454 The code here gets r,g,b value of part of the font which is 0,255,0 which i found through debugging (using print option). image = letters['H'] r,g,b = image.getpixel((1,1)) *Note r g b values are 0, 255,0* srcImage.putpixel((10,15),(r,g,b)) srcIma...

How do I merge a smaller image on top of a larger background image on one canvas. The smaller image will move around. So I will need to keep reference of the original background pixel data, so that the each frame the canvas can be redrawn, with the overlay in its new position. BgImage: 1280 x 400, overlayImage: 320 x 400, overlayOffsetX...
How do I blend these two sets of pixelData? The maskArray specifies the pixels to use from the OverlayData. These need to be merged with the backgroundData, and inserted back into the main canvas as newBackgroundData, and as offsetX changes update as needed. update I think I have found a solution: simply create another hidden canvas, a...
