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 :: 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?

Actionscript 3 :: Remove All Black Pixels From BitmapData?

Apr 19, 2010

Let say I have a BitmapData with different pixels representing an object, and some black pixels around it that I want to remove.I would like to obtain a new BitmapData, with width and height of the object represented by non-black pixels.For example, let say I have a BitmapData 400x400px, but the object represented by non-black pixels occupies the rect: x=100, y=100, width=200, height=200. I want to get new BitmapData representing that rect, all black pixels should be removed. Of course, i have no coordinates for that rectangle, i need somehow to make difference between a full black bitmapdata and the original one, and construct a new bitmapdata (different width and height).

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);

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?

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?

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.

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 3.0 :: Find Pixels By Color?

Mar 19, 2007

In another scripting language I have used for other purposes (AutoIt Script) there was a function called pixelSearch where you could find pixel locations based on a color. What I would like to do is develop a SWF that "reads" the colors of an image and applies a sparkle effect to the areas that are deemed bright enough (close enough to #ffffff). Ultimately, it would be really cool if I could make it figure out how large the bright area was to make a larger sparkle effect (increase size of sparkle MC) or that if it was too bright, it would assume it was background and not use the effect in that location.

This effect would be used to load various thumbnails from a database and render them in the browser, each with the same SWF but different image parameters, to make the images sparkle appropriately.

Actionscript 3 :: Removing Pixels Of One Color From A Bitmapdata?

Feb 24, 2012

I have a map (map of a mall, top view) with some colors. Iīm removing the part for walking of the map, which has a type of color (say 0xcccccc).

I got all the 0xcccccc color pixels removed (setted to another color), but it seems to remain a bit of gray at the walking part.

The color of that bit itīs close to 0xcccccc. It looks like flash not succeeded while removing the walking part. But instead, leaved some parts (like borders or something) on the bitmapdata.

Iīve tried to remove by script, by picking the colors remained on the bitmap, but the loop doesnīt find these colors.
