Flash :: Set CopyPixels To Ignore Transparent Pixels?

Mar 17, 2011

I 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);

ActionScript 3.0 :: Remove Transparent Pixels From Transparent Png?

Feb 27, 2010

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?

Flash :: Trim Away The Transparent Pixels Of The Image?

Nov 16, 2011

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?

Flash :: Narrow A Rectangle Within A Sprite To Exclude Transparent Pixels?

Oct 2, 2011

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.

Ignore Mouse Actions On Transparent Areas Of A PNG Using Flex Image?

Jan 5, 2012

I made a simple test Air application to try different approaches to masking or using hitArea to ignore mouse events over transparent areas of a PNG. Can't seem to find the right mix of things to make it work, nor could I find a succinct example on the web.Clicking on the transparent areas of any of these methods don't result in the click getting handled by the background.Here's the code I have:

Flex :: Color All Pixels That Are NOT Transparent To Black?

Aug 5, 2011

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.

[Code]...

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 3.0 :: BitMaps - Remove Transparent Pixels?

Jan 28, 2009

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.

ActionScript 2.0 :: Copypixel Not Replace Transparent Pixels?

Aug 4, 2009

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?

ActionScript 3.0 :: Draw Opaque Pixels On A Transparent Bitmapdata Background?

Oct 28, 2010

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"?

ActionScript 2.0 :: Slider Bars And Scaling - Code Keeps Shrinking Initial Object Down To 10 Pixels By 10 Pixels?

Jun 17, 2009

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..

ActionScript 3.0 :: Flash CopyPixels For MovieClip?

Aug 4, 2011

I'm not much of a scripter. I get by editing scripts similar to my needs. I learned a few things about blitting and I'm trying to get a rectangle area of a MovieClip to blit to a location on the stage. But I run into the error "Invalid BitmapData" which makes sense because I'm referencing a MovieClip and not an image. Is there a different AS3 command other then copyPixels that would work for a MC?

I know VCam would seem an obvious solution, however VCam scales to fill the entire stage. I only want to fill a small rectangle on the stage. I've already attempted to edit VCam with no success. Its probably not the same principle, but would it be possible to blit the matrix VCam uses?

ActionScript 3.0 :: Flash BitmapData.copyPixels And BlendMode?

Oct 4, 2010

I'm loading a batch of 50 jpgs and once loaded, on enter frame, I'd like to change their alpha individually and apply BlendMode.ADD to all of them (also individually).

I can do this easy using normal Sprite objects, but this is not efficient enough (processor wise). I've played a bit with BitmapData.draw(source, null, null, BlendMode.Add) and that's still not efficient enough.

So I was wondering if I could achieve similar effect using copyPixels (which I know should be more efficient). Still, I'm a bit clueless on how could I apply BlendMode and alpha on a bitmapData object (I mean, I know I can't, but I was wondering if I could make this work using Matrix and filter manipulations).

Actionscript 3 :: Rendering Flash Menu Over The Top Of Game Drawn With CopyPixels

Feb 20, 2011

I'm new to flash but have plenty of experience developing games, so when I started in flash I ignored pretty much everything that flash could do and just created a buffer the same size as my flash movie and drew my game direct to that with copyPixels. Now what I want to do is to add a menu to the game and it seems sensible to do make use of flash a little more. I can build a menu no problems in a .fla but can anyone tell me how I can render it over the top of my game?

ActionScript 3.0 :: Flash MovieClip / Bitmap X,y, Width,height After Scaling For CopyPixels Function?

ActionScript 2.0 :: Flash Ignore Text Characters?

Mar 19, 2010

I've created a quiz in flash that reads in questions and answers from an external xml file. E.g (xml).

<question q="allons-nous? = are we going/do we go?"
ans_a="allons-nous?"
right="a">

I have been asked to develop the quiz further so it ignores the case the answer is typed in (which I guess is possible using toLowerCase) and also to ignore any ! or ? symbols the user might type in .I assume the only way to accomplish this is to check the answer against a range of possible answers in the XML eg.

<question q="allons-nous? = are we going/do we go?"
ans_a="allons-nous?"
ans_b="allons-nous"
right="a",right="b">//this lines probably wrong

Does anyone know if there is any way of getting flash to ignore symbols if they are typed in?

Basically, I don't want the ADDED_TO_STAGE event handler to do anything at design time.
