I was wondering what the code to get something to go to a whole pixel value is. I'm using pixel fonts inside of a movieclip and when the movie clip is moved through actionscript and lands in a different spot with easing, the fonts look bad because i suspect that they are no longer on pixel values.

I'm looking for some help converting as3 code to pixelbender code in an attempt to improve the performance of my application. This as3 code goes as follows. I scan through the Number values of a bytearray in chunks. Lets say this chunk lenght was 100 numbers I read 2 numbers (left and right) and try find the maximum values. The numbers in my bytearray are PCM data so there is millions of them and this code can often take a long time to execute, especially on a low spec machine.
The whole aim of this is to render a waveform as quickly as possible. I know very little about pixel bender. I can basically make a new file and create a shaderJob of it in flash but I'm really uncertain how to approach this...

View 9 RepliesI'm writing an applicaton which acts based on different colour values of pixels in a png image created in Microsoft paint. However, when I load the image into a BitmapData object, and then parse through the pixels reading their values using getPixel() or getPixel32() (I've tried both) I seem to be getting values which are slightly inaccurate compared to what was saved. For example a pure white pixel which should be read as 0xFFFFFFFF often comes out as 0xFFFFFFFE. The behaviour of the program is dependent on the exact value of the pixel so these errors usually break it.
Sometimes the problem is intermittent so seems fixed but actually isn't. Is it to do with the PNG format? I thouht png was lossless so should deliver accurate pixel values at all times?

Using Actionscript 3 is there a way to search one bitmap for the coordinates matching pixels of another bitmap?
[URL]
Somehow you would have to loop through the bigger bitmap to find and the the pixel range that matches and return those coordinates. For example the Bitmap with the "E" is 250 pixels over and 14 pixels down in the bigger bitmap.

View 2 RepliesI am looking for a fairly simple image comparison method in AS3. I have taken an image from a web cam (with no subject) passed it in to bitmap data, then a second image is taken (this time with a subject) to compare this data, from these two images I would like to create a mask from the pixels that match on both bitmaps. I have been scratching my head for a while, and I am not really making any progress. Could any one point me in the right direction for pixel comparison method, something like getPixel32()

How do I programatically get the pixel dimensions of my SWF. I tried using stage.width and stage.height, but this seems to be a tight bounding box on all the objects in the video, not the actual viewing area. I also want these pixel dimensions to be accurate as javascript dynamically resizes this SWF.
View 2 RepliesI have a Flash CS3 movie (AS2) wich uses pixel fonts. The text is within a movie clip that uses the tween class to move with ease. Whe I publish it, everything OK, the text looks very crispy. But I want this movie to be centered in the browser window so I've used the tags <center> </center> in the html file as you can see below. When you play the movie it plays in the center but... with IE8 the text is blurred if the browser window is maximize, but crispy if you minimize the window!! With other browsers it works well with all windows sizes, IE7, Firefox, Safari...

When the user clicks a point inside the triangle, we will get the x and y coordinates, do some calculation with those values and get some (lots) of pixel coordiantes accordingly (all of those calculated points will be within the triangle). And finally, change the color of those points (something different than triangleShape fill color).
I have a website with a Flash banner. This has worked fine in all major browsers (IE7/8,Firefox, Chrome, Safari, Opera) for some time, but when I upgraded to IE9, the banner is displayed with a 1 pixel shim on the right-hand edge, which is throwing the layout off.know past versions of IE would display line breaks as white space and I wonder if that's what's going on here. I'm using the AC_FL_RunContent() function to display the Flash file.I'm not sure where to look to debug this, but I'd like to fix it sooner rather than later
View 3 RepliesI am trying to set a constant hue value for entire image with using ColorMatrix. My goal is to make entire image look with same color without loosing brightness of any area. I found a way to shift the hue values of an image by using ColorMatrix but i couldn't find any way to set same hue value for all pixels. I can do it with iterating every pixel of image but this approach is too slow. I am not sure if it is possible to do it with ColorMatrix and i am open to possible solutions other than ColorMatrix approach.I can do this with iterating pixels but not with ColorMatrix.I am trying to do this on Android but i believe the question is not directly related to the android since ColorMatrix approach is common on other platforms like Flash, C# etc.
