I'm trying to use copypixel to copy an image and paste it onto an existing bitmap. However, the image I'm trying to copy has transparent pixels so when CopyPixel's pastes the image onto my existing bitmap, the pixels already on the image is replaced by the transparent pixels from my image.
How can I make it so CopyPixel will only paste all pixels besides the transparent ones onto my bitmap?
I 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?
View 2 RepliesI want to create a SimpleButton that has some PNG/GIF graphics as the down/up states. Part of the pixels are transparent and I don't want them to be clickable, is that doable?
View 9 RepliesI have a BitmapData object with transparency (the sourceBitmapData parameter). Every time I use copyPixels() to copy it onto another BitmapData object the transparent pixels replace whatever is beneath them. I would like the copyPixels() function to simply ignore these fully transparent pixels (0x00) and NOT copy themBTW, I've tried setting the alphaMerge to true but that doesn't solve the issue - the whole source object just goes black and ignores ALL transparency.EDIT:
Here are the code snippets;
var b:UIComponent = new UIComponent();
b.graphics.beginFill(color, opacity);

I 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.
I have a Flash fla file that contains a whole lot of images. The majority of each image is composed of transparent pixels with a visual object in there somewhere. Each image at the moment is at {x:0, y:0}.I want to trim away the transparent pixels of the image down to a minimum bounding box, but keep the object at the same global position. This requires shifting the trimmed image to the global position of the object in the untrimmed image.This is not so much a problem, but the fact that the images are all contained in a fla is the problem. The options I see at the moment are:
investigate JSFL, the Bitmap object has a getPixels, this in combination with a selection and delete operation could work save the fla to xfl and enumerate the images and associated xml with something like Ruby + image processing lib
Questions: Does anyone know upfront if this operation is possible in JSFL? Have anyone done much automated processing of xfl files? Is there an off the shelf image processor that can perform this trimming operation?
Iv created an app in work which needs a rubber. I basicly have a tool to draw line (paint/pencil). This draws over the entire stage area, including over buttons and interactive mc's. Once i draw the line i then want to be able to erase bit of it.
To this end iv made an eraser tool, which works well. I turn the line into a bitmap, then turn the eraser line into a bitmap and use BlendMode.ERASE to erase one from the other. My problem is, because when creating the bitmatdata i have to create a rectangular shape, the area created then means that i cant access any of the buttons underneath.
here is my code:
ActionScript Code:
//line array is an area of all the line objects which are currently live on stage.
for(var i=0; i<lineAr.length; i++){
[code]....
The way i see it i need to remove the transparent pixels from delBitMap once the erase has been done.
Is there anyway I can do a hittest that ignores transparent pixels? If so how would I do it.
View 2 RepliesI 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?

I have a Sprite that contains opaque objects surrounded by transparent pixels. I also have a Rectangle that represents a part of the Sprite that I want to render using BitmapData.draw(). The problem is that the Rectangle that I obtained also contains transparent parts. How can I narrow the Rectangle to only include the opaque parts and ignore the transparent surroundings?
kapep's answer is just what I want to do, but the problem is that the source is a Sprite, not a BitmapData object, and I don't have getColorBoundsRect() on a Sprite.
im 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"?
Is there a way to trim a bitmap so that the width and height are not effected by transparent pixels?
View 5 RepliesI 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?
so instead of the pixels being dissolved, the pixels being added? :
ActionScript Code:
var Anim:TransitionManager = new TransitionManager(blackbox);
Anim.startTransition({type:PixelDissolve, direction:Transition.OUT, duration:1, easing:None.easeOut, xSections:35, ySections:35});
basically what i would like is the end point to be the start point and the start point the end point.
I 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..
I have a movie clip called column1_mc. when I click a button I need to move the movie clip in incremental moves consisting of 30 pixels.
column1_mc._y = 30;
Does not work because that is giving a _y coordinate.For example.I need to make the movie clip jump to _y 300 but make 10x30 pixel incremental jumps. Moving 10 times 30 pixel jumps.
i got an issue about copyPixel.
my goal is : use copyPixel to move the bitmapdata itself a little bit.(not a.copyPixel(b) just a.copyPixel(a) )

I was wondering if it would be possible to use copyPixel to create a simple text printer for example you have a font as an image like this
[URL] then have some code that will transform your text ="hello world" into HELLO WORLD on your flash screen, but written in that font.
Because the font is spaced equally you could have the source x and y, times by 16pixels for each letter and move the Y source down 16 pixels when it reaches the right side of the image
I am going to start using copypixel and I wonder if I am understanding the concept well. I am having doubts about memory use. This is my question: If I have an external image (tile map) I loaded , each time I use copypixel to copy a region from this tile map, I am using additional memory or only the map is located in memory? In my application I need to copy a bitmap region from a tile map to a variable (var 1) and then copy another region from this var 1 to a second one (var 2). My concern is to increase the use of memory.
View 5 RepliesMy game moves small pieces slowly. I am trying to bitmap blit with either CopyPixels() or Draw() but because the end result always blits to a whole pixel value, the animation looks choppy. Have a look at my test swf where I use a small helicopter, which shows 60fps with very choppy movement. I thought the bitmapData's draw() method would allow me to smooth, but it apparently only smooths changes made by it's matrix argument. My only other resort is to go back to using movieClips with hundreds of frames that represent the various poses.

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 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've got a strange situation where I'm replacing the text in a string that I've taken from an XML, but the .replace function for the string keeps failing. I've tried running the example given on the Adobe site, so I know the value I'm trying to replace ("%20") isn't at fault - it's something about the string I have! I've included the code below, but it seems correct. Is there a particular tip I should know when taking XML values into AS3? I'm putting them in strings for this project.
