Is there any way of checking what percentage of the BitmapData is filled, and what percentage is transparent?You could easily brute-force it by looping through each pixel and counting which ones are empty

I'm trying to draw PNGs onto BitmapData that is transparent.
I create my BitmapData like this (using ARGB for the color):
new BitmapData(width, height, true, 0x00000000);
And clean it by using the same ARGB value:
bitmapData.fillRect(bitmapData.rect, 0x00000000);
When I use copyPixels() to draw graphics onto the cleaned BitmapData, I get this result:
If I don't use ARGB for the BitmapData color, it works fine:
But I have to specify a solid fillColor, meaning I can't render what's behind the Bitmap.
How can I make my BitmapData transparent, but not have the above occur?
I'd like to know if there's anyway I can compare two BitmapData and get a "similarity percentage" (knowing how look-alike they are). I've done a bit of research and came across bitmapData.compare(otherBmd), but that only returns if they differ in size, or pixel, and not how much they differ. The point of this was to compare some Bmd obtained through a camera with a library image (so this is what I got so far):
import flash.display.Bitmap;
import flash.display.BitmapData;
var img1:BitmapData = new monaLisa();
var cam:Camera = Camera.getCamera();
var video:Video = new Video(camMock.width,camMock.height);
video.attachCamera(cam);

I 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?
View 3 Repliesi am loading a background bitmap into a sprite. after that i make this sprite draggable. now i would like to have a copy of this sprite where just the area with the non-transparent parts of the bitmap react to the click.
i know that i can determine if a pixel is transparent with the getPixel32() method, but it seems to be overkill to anylyze every pixel... or is it not?
I am trying to detect if a point on an image is on the opaque part of the image or the transparent part. I have a image in a 48X48 area. half the image has transparent pixels. I seem to detect a hit on every part of the image like a bounding box test but I don't want that. For example . I place a 48X48 size image on stage at 0,0. At point 40,20 on the stage the image has transparent pixels but I get it detects a hit?
mm.img.hitTestPoint(40,20,true); //it should give me false

I want to make the white color in the generated PNG transparent.
I have a huge background bitmapdata with a corresponding grid. I'm trying to draw the two parts onto a different bitmapdata, but for some reason, the bitmap for the grid is overriding the bitmapdata of the background that is being drawn first. The grid seems to be making the entire third bitmapdata transparent for some reason.
My code for creating the background and corresponding grid:
Code:
viewWidth=stage.stageWidth;
viewHeight=stage.stageHeight;
bmdScreen=new BitmapData(viewWidth,viewHeight,true);

I want to draw a grid on top of the background I have. For some reason, the grid is making the background underneath it transparent.
I have a list of images, and without scanning through each pixel in each image, I want to find out if the image contains transparency (at least one non-opaque pixel).Is there a shortcut to do this (like a property of bitmapData object) rather than looping through the pixels?

View 1 Repliesim trying to draw opaque pixels on a transparent bitmapdata background
heres the ex:
ActionScript Code:
//TRANSPARENT BACKGROUND
var _pixelColor:uint = 0x9998002E;
var _bmpd:BitmapData = new BitmapData(4, 7, true, 0x00333333);
[Code].....
This example paints 2 arrows, the first is using the transparent background, and the second is using an opaque background on the BitmapData.
What I'm trying to achieve is to paint the pixels of the arrow completely opaque on the transparent background. But as you can see, the pixel is at 99% of its opacity (var _pixelColor:uint = 0x9998002E) How can I paint 100% opaque pixels on a transparent BitmapData "canvas"?
I 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:
[AS]
bmpd = new ImageFromLibrary(0, 0);
bmpd.setPixel(0, 0, 0x00000000);
[/AS]
why its not setting the pixel(s) transparent?
I have two png files. I import them using loaders. The images in the png files each have opaque (solid) and transparent parts. I want to use the bitmapdata.hittest method to detect when their opaque parts have collided.

I've been working on this for a couple of days now and nobody seems to know how to do this. Please don't post the examples on google, I've looked through at least the first five pages of results on google and haven't gotten any of them to work. The problem is that none of them provide an example of using this method with loaders, so I'm guessing the reason I can't get it to work is some gimmick associated with them.
I have this function:
public static function cloneDpObj(target:DisplayObject):Bitmap
{
var duplicate:Bitmap;
[code]....
to clone target displayObject (MovieClip or Sprite) and return Bitmap Object.
It can get bitmap from the target object, but it seem don't get all the area of the image.
By give the width and height of target object, but the target object in design was applied by Glow Effect, so my question can we get the all view of bitmapdata from a displayobject?

I am trying to use the reflect class from "http://pixelfumes.blogspot.com/2007/03/reflection-class-v3-with-source .html" but I keep getting this error:

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.

View 2 RepliesI am creating a map in flash cs4 with all the countries on it. I used photoshop for creating the map and separated countries. Now I imported all pngs in Flash and I want to give Mouse CLICK event and Mouse Hover on all pngs, but as the transparent pixels are overlapping the other states, it is getting difficult. So, I converted all pngs in movieclips and now then I broke up pngs. Now I want to delete all pixels having alpha 0 using eraser tool, as per the borders. And I have to do it manually for individual countries. So is there a way to remove transparent pixels from the bitmap data?

I have two png's that kind of look like paint brush strokes. they have some transparency in them that lets the stage colour bleed through a bit.
I am adding two of these images to the stage in AS 3. One adds quite fine - looks as expected. The second one however doesn't have any transparency other than around its edges. What i mean is it looks more like GIF than a PNG. Rough around the edges, no transparency "inside" the image itself (where there should be)
i have tried re-creating the image (yes it IS a PNG) which did nothing. I ensured the library item is not being treated as a JPEG. I also even tried externally calling the PNG to see if that made a difference. Unfortunately it did not.
why this second PNG doesn't seem to have a transparency set?
I am having an issue with using BitmapData.draw(stage). I am getting the following error:

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.
there are few comments i hear from other people. some say the axis of the carousel crooked and the icons are pixelated when they are scaled down. i m trying to add a transparent video of myself in the center but when i mask the carousel the embeded swf files also get the mask so i was wondering if there was a way to make the icons have alpha 0 when they are back all the way.. here s the link for the regular website [URL] and below is my actionscript
