In my flash IDE library there's an imported jpg Image. Its class base is automatically BitmapData. How to get its data ? The following doesn't work:[code]But how to do without using away3d just for it!?
View 5 RepliesI'm using Flash 8, with this code in the first frame:

When I publish the file, I'm getting the following error message in the Output panel:

private function getBitmapData(className:String):BitmapData[code]....
I want to return bitmapData from a symbol that is embedded in a flash swf file. background01 is the class name exported to as3 in the flash swf file. As you can see from above I'm finding the swf with no problem. and I'm pullin the data back from the swf file with no prob. I can type addChild(new background01) and the image will show up. But when I've tried to cast to a bitmap , bitmapasset and movieclip. It always returns null. I want to get access to the bitmapdata of this image/movieclip. It should be returning a vertex circle drawn in flash and created to be a movieclip symbol. So what I would expect to be returned would be a MovieClip.
I am working with the BitmapData class for the first time for a transition and I am running into a problem loading a new image from the array. I have modified a tutorial from flash-db by Jorge Solis. The function dissImg is firing but I can't work out how to load another image from the array into the container! Please see the code below:
Code:

I am using BitmapData to draw the objects in my game. But, I'm not sure I am using this in the best way.In each class I have a draw method where I call a renderer where copy the pixels of my object to the game canvas.For example, I have an Avatar class and its contains a BitmapData instance. There is a method where I draw my character into the bitmapdata of this class and I apply the filters or visual modification I need frame by frame. When I finish this process I copy the result to the main canvas. It is in a renderer class that contains another bitmapdata.I believe this is not the best way to render the objects of a game.

I'm trying to use BitmapData Class to capture an animated movieclip and adding it to the display list by using addChild, but it's causing my computer to bog down because it's adding a zillion children. what do I do to remove the old, or rather, update the current child with the new one?

View 1 RepliesI 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 ?
View 1 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.

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've been using BitmapData.copyPixels() to draw graphics onto a canvas (Bitmap).I need to rotate the resulting graphics without the use of draw() because it's vastly slower.How can I rotate the target graphic? I'm assuming that there might be a formula or library that I can use which will first reorganize the pixels that make up a graphic based on an origin (point) and radians.I'm pretty certain that I'm not capable of creating such logic, so if there are any known libraries that do this, that would be awesome.I'd like to achieve something similar to XNA's SpriteBatch.Draw() method, which accepts rotation as its 5th argument.

The title might be a little misleading. Look at my code and I will explain

I am trying to do tiling with sprites. I want my tiles to be interactive, so that is why I am using the sprite object instead of using regular bitMaps to represent my tiles. You might be wondering why I wouldnt just use graphics.beginBitmapFill(tImage); and graphics.drawRect(0, 0,tWidth ,tHeight ); to pick out the tiles I want to use. Well reason being is because it turns out that drawRect() first and second parameters actually alter the location of where the actual sprite sits at.
So if I set the x and y properties of the sprite to x = 20, and y = 20. then I set my drawRect(20,20). it actually adds an extra 20 pixels to my x and y coords of my sprite. And I know the reason why, I just need to know a better way.

View 4 RepliesSo due to my lack of time to research this and my strong curiosity for the matter:Does anyone know of any publicly available classes or ways to convert an array of BitmapData to a video format ByteArray (going to save it since I'm using it in an AIR project)?
I was considering writing my own class for it but started in the research and decided it's a very highly developed field and is hard to quickly find the basics of how to handle it. Thus it's usefulness outweighed it's opportunity cost for the time I have unless there is an already made class for handling this.
Mainly was considering this for short clips that one would create for logos etc so that one can display the logo in other environments with ease.
I have a bitmap with a different bitmapData on it (done through copyPixel) and I was wondering whether there is built in function that can determine what BitmapData the user is clicking on? how to best figure out which BitmapData is clicked, or do I have to do x,y pos comparisons manually?

I'm trying to replicate this function from the Allegro graphics library:

This is somewhat difficult in Flash, because of the overlapping functionality between the Rectangle and Matrix arguments of AS3's BitmapData.draw() method. This is what I have so far. It only works most of the time, and is incredibly inefficient (due to having to sample pixels twice).
function stretch_blit(src:BitmapData, dest:BitmapData, source_x:int, source_y:int,

View 1 RepliesI need to load a very big image on AS3 (currently sized at 8192x8192). I am aware that it does not fit any of the limits imposed by Flash regarding drawing to screen or creating a BitmapData of that size. I just want to load the image so I can copyPixels() some parts of it here and there.The thing is, I'm loading the .jpg file of that size with no problems. The size is recognized correctly from my Loader object. I load it like this:[code]But I am greeted with the #2015 "Invalid BitmapData" error usually reserved for BitmapDatas that are too big. The error also happens if I try to do a copyPixels(), which is what I need to do.Is there any workaround I can use so I can get data from an image this big on AS3?
View 1 RepliesI have a BitmapData object created dynamically that contains user-drawn shapes. I then attach that BitmapData object to a MovieClip via a Bitmap object and set that MovieClip as a mask to another MovieClip. The mask works but the whole bounding rectangle of the BitmapData is acting as the mask. But I want to exclude the transparent portion from the mask so only user-drawn shape can be set as mask. Can anyone tell how to achieve that?
