Actionscript 3 :: BitmapData Copy Pixels Half Pixel?

Feb 17, 2012

Having trouble trying to scroll BitmapData on a half pixel here is my original code

var speed:Number = 1;
_bitmapData.copyPixels(_backgroundParallax, _screenRect, _zeroPoint, null, null, true);
_backgroundParallax.copyPixels(_backgroundParallax, new Rectangle(0, 0, speed, _backgroundParallax.height), new Point(_backgroundParallax.width-speed,0), null, null, false);
_backgroundParallax.scroll( (speed*-1) , 0);

which works until i change the var speed to .5, which is because .scroll method is expecting int's so i replicated what scroll is doing to try and allow .5 pixels

Actionscript 3 :: Quickly Rotate The Pixels That Make Up BitmapData Without Using BitmapData.draw()?

Dec 29, 2011

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.

ActionScript 2.0 :: Half Pixel - Keep The Movie Clip Centered

Dec 17, 2010

I've finished a site that has a listener with no scaling. Basically its the typical /2 deal to keep the movie clip centered. On a few images I have a 1 pixel black frame so the images need to remain on whole pixel locations to remain crisp. Generally everything works well but sometimes when you resize the browser just right it somehow puts them in between pixels.

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).

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. I´m 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 it´s 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.

I´ve tried to remove by script, by picking the colors remained on the bitmap, but the loop doesn´t find these colors.

ActionScript 2.0 :: BitmapData Clear Pixels Or Set Alpha

Feb 26, 2008

What I have setup right now is one movieClip that is being used to be drawn into a BitmapData object. That bitmapData object is being drawn on the enterFrame and I am needing to clear it so it doesnt have the previous enterFrames information still stored in it, then once it is clear draw the current information. Is there a simple way to clear or erase all the pixel information in the BitmapData object?

If there is a way to set the alpha of the pixels I would really like to know how that is done as well. However, I want to change the alpha level of the entire BitmapData object, not just a few pixels.

Professional :: Pixel Colors In BitmapData.noise?

Oct 5, 2010

I am wondering if there is any way to set the pixel colors exclusively to black and white (instead of gray) in a bitmapData.noise animation. The previous related thread is: [URL]..For the function:
 
function makeNoise():void { _bitmapData.noise(getTimer(), 100, 255, 7, true);
 
Is there any way to set the noise color pattern to black and white? In the scripting reference, it seems the choices are R||G||B||Alpha channels, so I am not sure if there is any way to combine these to get black and white only.

As3 :: Flex - Handling Inverted Pixels In BitmapData And Bitmap Class

Mar 29, 2010

I 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 ?

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"?

Flash :: Search BitmapData Object For Matching Pixel Values From Another Bitmap?

Jun 16, 2010

Using Actionscript 3 is there a way to search one bitmap for the coordinates matching pixels of another bitmap?

[URL]

Somehow you would have to loop through the bigger bitmap to find and the the pixel range that matches and return those coordinates. For example the Bitmap with the "E" is 250 pixels over and 14 pixels down in the bigger bitmap.

Flash :: Copy Channel (BitmapData Class) - Eraser Tool

May 3, 2011

I 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.

The first time you click the button the fading movieclip plays as it should, fading in and out continuously. However, the second or subsequent times the button is clicked the fading movieclip goes crazy, half fading in/out and half jumping from one alpha value to another.
