Nov 23, 2011I got one bitmap with a (almost) one color background. i need to change all of this with pixels at same x,y from another bitmap.
I know i need to run it through a double for loop and then into an if sentence.
like this:
If (color at x,y is > redvalue && color at x,y is > greenvalue && color at x,y is > bluevalue)then exchange with pixel from the other bitmap.

As3 :: Flex - Handling Inverted Pixels In BitmapData And Bitmap Class
Mar 29, 2010I am using bitmapData and bitmap classes to render a mouse cursor on the display screen. The bitmapData consists of an area whose colors should be inverted according to the background color. This is a very basic thing which could be observed with text cursor(the vertical line with two small horizontals on top and bottom), when moved over the text area. want to be able to do the same with the pixels in my bitmapData, is there a way to find out the background color effectively and invert the color values? In this process i will be redrawing the whole pixels, is there any other efficient way to do that ?

May 2, 2009I am trying to use the bitmapData.setPixels method to set certain pixels in the bitmap transparent.But no matter what I do, it always seems to set the pixel(s) black (non-transparent).Here is my code:

ActionScript 3.0 :: Find Pixels By Color?
Mar 19, 2007In another scripting language I have used for other purposes (AutoIt Script) there was a function called pixelSearch where you could find pixel locations based on a color. What I would like to do is develop a SWF that "reads" the colors of an image and applies a sparkle effect to the areas that are deemed bright enough (close enough to #ffffff). Ultimately, it would be really cool if I could make it figure out how large the bright area was to make a larger sparkle effect (increase size of sparkle MC) or that if it was too bright, it would assume it was background and not use the effect in that location.
This effect would be used to load various thumbnails from a database and render them in the browser, each with the same SWF but different image parameters, to make the images sparkle appropriately.
ActionScript 3.0 :: BitmapData - Pixels Must Have Specified Gray Color Value
Aug 1, 2009I need to create, from a given Bitmap/BitmapData of a PNG file which has transparent and semitransparent pixels, another BitmapData which is a copy of it, but all the pixels (well, the pixels that are not alpha 0% actually) must have a specified grey color value (0xdddddd).
View 2 RepliesFlex :: Color All Pixels That Are NOT Transparent To Black?
Aug 5, 2011I am using ColorMatixFilter on an Image in Flex. I am really close to getting want I need out of the filter.Basically any PNG file the user uploads I want all pixels that are not transparent to be colored black. I have a function that sets the "brightness" already so I just through a really large negative number at it like -1000 and it does the job but the problem is any pixels that have any alpha to them, say 0.9 or below all end up being white when I encode my PNG file on the server later.

I would like all pixels to be solid black unless the pixel is completely transparent and not sure how to tweak the values to get that out of it.
Actionscript 3 :: Removing Pixels Of One Color From A Bitmapdata?
Feb 24, 2012I have a map (map of a mall, top view) with some colors. I´m removing the part for walking of the map, which has a type of color (say 0xcccccc).
I got all the 0xcccccc color pixels removed (setted to another color), but it seems to remain a bit of gray at the walking part.
The color of that bit it´s close to 0xcccccc. It looks like flash not succeeded while removing the walking part. But instead, leaved some parts (like borders or something) on the bitmapdata.
I´ve tried to remove by script, by picking the colors remained on the bitmap, but the loop doesn´t find these colors.

ActionScript 2.0 :: Slider Bars And Scaling - Code Keeps Shrinking Initial Object Down To 10 Pixels By 10 Pixels?
Jun 17, 2009I have a swf file that loads into my main movie, and within that swf there is a masked image that i would like to scale using zoom in and out buttons and also by using a slider bar.However i cant find any tutorials that will allow me to combine the two.I have used the following code for the buttons. Which seems to work ok but i would like it to be a little smoother. (using speed or some sort of easing??)
ActionScript Code:
zoomPlus.onRelease = function(zoomIn) {
if (test_shirt.shirt._xscale == 400 && test_shirt.shirt._yscale == 400) {[code]....
but for this code it keeps shrinking my initial object down to 10 pixels by 10 pixels..

Sep 17, 2009I have a movieClip over which I want to apply color effects such as making it flash white or in any other color.I can actually do this by duplicating that movieclip and use that duplicate as a mask...But, considering that movieClip is animated through code and is kinda complex, it somehow doesn't feel very optimized.I was wondering if there was a way to tell actionscript to "draw the color only over the pixels that constitute the rendered shape", rather than creating a complete duplicate.

View 23 RepliesProfessional :: Convert Bitmap To 256 Color?
Sep 3, 2010Apparently, in order to make a bitmap transparent, one has to convert it to 256 colors from 24. I'm not sure if Flash puts it in 24 or 256, but because I can't create a transparency when using Bitmap() in my code, and from what I see displayed on the screen, it would appear that it uses 24 colors. Perhaps this is to keep things light. Nonetheless, is it possible to convert it to 256 colors?

View 1 RepliesActionScript 3 :: Most Common Color In Bitmap (Data)

But the function has to be as light as possible so my question is; Is there a more lightweight approach to achieve this? The function is used to extract background color of a Bitmap.
