I have two BitmapData objects with alpha channels. I'd like to combine them into a single one by using max(channel_image_one, channel_image_two) for each channel, including the alpha. Is there an easy way to achieve this result?
View 2 RepliesI have a BitmapData object with an alpha channel. I'd like to know the fastet way to offset that alpha channel in ActionScript3 (FlashPlayer10). By offsetting I mean shifting all pixels of that channel in one direction (wrapping around the image borders) while leaving the color channels as they were.Is there a good way to apply a such a transform to one channel only?
View 2 RepliesI am developing an application similar to MS Paint. I am building a Flash Paint application. The basic structure is this. I have two layers namely topLayer_mc and bottomLayer_mc. The actual vector drawing is drawn on the top layer and onmouseUp of the tool, a bitmap copy of the vector graphics on the top layer is taken and added as a bitmap to the bottom layer. The top layer is cleared subsequently. It is working for the pencil tool.
Now I need to create an eraser tool. This is where things get tricky. In the application there is an option to save the image as png, so alpha has top be preserved. So the coventional method of draw a brush using the vector and using the draw method of bitmap will not work. Of course, on a visual level it would work if the brush drawn using the vector is to have the same color as that of the background. The eraser's are rectangular in shape.
The technique I am tring to use is to use the copyChannel method of BitmapData class. Specify a channels (say GREEN channel )hex value as 00 and make it as the source. Then make the destination channel ALPHA. I got it working without using movieclips as shown below.

Set 2 MovieClips on the stage each having a rectangle in it which have different colors. Put them one over another and apply to the top one some blend mode that shows some visual difference. Ok so what I need to do now is grab the bitmapData from both and redraw it into a single MovieClip, so what I need is to merge the 2 bitmapData, which worked fine without a blendMode, but I can't get it to work right with blendMode[code]...
View 3 Repliesreason is i'm copying this grayscale Perlinnoise smoke image and makig it such that the darker the color, the more transparent it is. (I'musingcopyChannel.RED/GREEN/BLUE->CopyChannel.ALPHA). But right now, it's the other way round at the moment (ie. the brighter the pixel, the more opaque it is.). I want it to be more transparent instead (inversely proportional), so if i could find simple & fast way invert the alpha channel, it would do me so much more good. (I need a fast method...performance is critical!)

View 3 RepliesI am creating a program that is effectively an sprite creator. I'm very new to AS3, but I know JQuery, JS, PHP, etc. After going through multiple steps of selecting pieces to customize a character, you are supposed to be able to download the final product using fileReference(). Everything works, and I can download the image in the end, but the problem is that I cannot capture all of several movieclips on the stage, I can only capture one. Maybe this will help clarify:

Could it be that each of the movieclips I'm adding to the sprite have children of their own?
The following code is a combination of samples taken from red5. Basically I am trying to combine a live stream subscriber with a chat box based on shared objects. I'm not a flash developer and have a very limited understanding of what is going on here.
// ** AUTO-UI IMPORT STATEMENTS **
import org.red5.utils.Connector;
import org.red5.samples.simplechat.BasicChat;
[code]....
I don't think that var chat is being initialized anywhere as trace(chat) prints 'undefined'. However var connector and var publish_video seem to collect their instances from the stage.
This sample code included those two and worked fine, but I can't make my additions behave the same way.
I have added an instance of BasicChat to the stage (I'm using Flash CS4) and have spent the past many hours playing with it's various properties, layers and groupings, but to no avail. why my var chat isn't collecting its instance from the stage?
Are BitmapData objects automatically GPU accelerated for rendering, rotating, and scaling,or does the bitmap they connect to need to have cacheAsBitmap set to true?
View 1 Repliesis there anything that will take a very large png (even larger then the total pixel limit of BitmapData) and load in the png as raw bytes into a bytearray and then take that array and grab only portions of the image to be able to generate a grid of usable bitmaps to render the very large png..I got to the point where I was able to get the png as a bytearray but from there I don't know how to grab a portion of the bytearray and attempt to load the partial bytes in a loader via loadBytes()..basically I think I need a decoder to decode the partial bytes to a bitmapdata.
View 2 RepliesHow to dispose bitmapdata objects that have no linkage. The thing is that I have bitmap pictures (PNG) wrapped inside movieclips (as you can't set linkage to PNG files with jsfl) and when I begin to load them into my movie from the library I can't dispose of them to free up ram memory, i've tried to use movieclip.removeMovieClip(); and movieclip.dispose(); but the bitmap inside still takes up ram! I use over 1000 pictures so i really need to dispose them... How to get linkage set to PNG files with jsfl??

btw, first I used assigned thumbContainer as the mc argument (outside the loadThumbs() function) and it worked but not exactly what I wanted... because I thought it is supposed to update when the movieclip is animated but it actually didn't... when I use a scroller, only the thumbs that are first loaded to the stage get the reflection..
I'm trying to know if you can copy the pixels of many objects in one BitmapData without a huge slowdown. The slow down is made by calling the method multiple times, thus making a lot of variable declaration and disposal for the garbage collector. If someone know how to either immitate the copyPixel method or have any other way of solving this problem,
View 4 Repliesi have the following situation:
one drawing layer (graphics object with lineTo, etc.)
one png with an alpha channel (supposed to serve only as a mask)
now i want to be able to only draw lines within an area restricted by the png mask.
i am trying like this:
var bitmapData:BitmapData = new BitmapData( 320, 320 );
bitmapData.draw( drawingLayer );
bitmapData.copyChannel( maskBitmapData, new Rectangle( 0, 0, 320, 320 ), new Point( 0, 0 ), BitmapDataChannel.ALPHA, BitmapDataChannel.ALPHA );
now the borders get cut off fine, but i get a black background, since the drawing layer has an alpha between the drawn lines (and it should remain like this) and the mask bitmap has an alpha outside the shape. so naturally the mask's alpha replaces the drawing layer's.
i tried it with merge, copyPixels and also with just setting the mask property on the drawing layer (i set everything to cacheAsBitmap) but to no avail.
ADDITION:
when trying to use a mask i tried it with
<s:BitmapImage id="mask" source="@Embed(source='...')" cacheAsBitmap="true" />
and also as
[Embed("...")]
private const BodyMask:Class;
var maskBitmap:Bitmap = new BodyMask();
and assigned them to the mask property of a s:Group element (cacheAsBitmap=true) where the operations on the graphics object occured. i also tried reassigning the mask after each draw operation.
The code below is a simple add and save program. You press the addButton to add content to the canvas and than press the exportButton to save an image of the canvas in its current state to your desktop. This code works fine when I add circle objects to the canvas that are drawn to the canvas. The problem lies when I try to load a .png into the canvas. Once the loaded content is added to the canvas the exportButton stops working all together and no longer responds. What is causing the loaded content to break the code?

I am drawing a flash sprite on a BitmapData using its draw() method. This sprite has some nested objects with 0 alpha, yet the draw() method draws them on the bitmap data.
I think it has to do with the color transform I am using, but I have no idea how to change it to achieve the effect I want.
The color transform is the following:
Code:
new ColorTransform(1, 1, 1, 1, 255, 255, 255, 255);
I am using these values in order for the Bitmap to have white pixels wherever the object was, and black where there is nothing. The draw() also draws my alpha = 0 objects in white as well.
Photoshop and Fireworks both have some nice filters. When you put one bitmap over the other, the first bitmap can act as filter. For example, the white pixels of the top bitmap lighten the pixels of the bottom bitmap. Is there any way to apply this in as3? What I am trying to accomplish: I have a large single-color bitmapdata object. I want to overlay perlin noise and lighten/darken the single-color bitmap to give it some random/natural look.
View 1 Replieshi guys, i got this image i scaled down by .5. The user is then allowed to add objects to the image such as flowers that are sprites in the library. So basically, a jpeg that is 800 x 800 is down to 400 x 400 on the stage and the user is able to add objects to overlay the image.
i want to save the image with the flowers and objects back to its 800 x 800, how do i redraw this image using bitmapdata properly?
The only way i can describe this is showing the code I have already then trying to explain what i want to do.Basically, I am creating a soundboard game, where at the bottom of the screen I will have a bar which is a movieclip, and I will be dragging other movieclips onto it and then clicking pay, and using an array and .push they will play in order.

Im wondering if its possible to combine flash animation over a background of live action video using Flash? I'm looking for an effect similar to the movie Roger Rabbit...
I have done some experimenting, and I realize that its possible to import a live action video into flash and then do some animation on another layer and then publish it - but with this method its essentially impossible to guess the timing of the live action video...
import a live action video into flash and actually see the timing /frames of the video within the Flash IDE? Or should I be using something like after effects?
