There is a new release of the ImageProcessing Library out for you people. I do not have that much time to spend but I hope that this is a helpful library and will even grow a lot.

• Download
• Documentation

Here is a small changelog:

• Publish class util to send images in an easy way to sockets or websites
• Format exporter (PNG, JPEG)
• New core class for multiple layers
• ToneMapping filter
• Noise filters (GaussianNoise, UniformNoise, PerlinNoise)
• Drawing util

I guess that there are a lot of small changes here and there but nothing special. I also want to implement some more filters later maybe. Right now the next thing I really would like to have is an online playground where you can load pictures from flickr or take snapshots from your webcam, mix them together and save them. The only problem is that this needs some sort of GUI and this is where the problems begin and my timescale shrinks. So you will have to wait for that. I am also looking for contributors. If somebody wants to share his filters or effects just send me an e-mail (address is on je2050.de).

Here is also a code sample. I will come up with more stuff and update the zip-archive aswell. This little piece of code generates the image you see on top of the post.
[as]var backGround: Image = new Image( 700, 200, ImageFormat.RGB );
var text: Image = new Image( 700, 200, ImageFormat.RGB );
var textGlow: Image;

Drawing.drawText( text, 0xffee3399, 120, 20, ‘ImageProcessing Library’, ‘verdana’, 32, true );

textGlow = text.clone();

new PerlinNoise( 700, 200, 8, 0xABC, false, false, PerlinNoise.CHANNEL_RED | PerlinNoise.CHANNEL_GREEN | PerlinNoise.CHANNEL_BLUE ).apply( backGround );
new Blur( 8, 8, 3 ).apply( textGlow );

var layerManager: LayerManager = LayerManager.fromImage( backGround );

for ( var x: Number = -240; x < layerManager.width; x += layerManager.width / 100 )
Drawing.drawLine( layerManager.backgroundImage, 0x80008888, x, 0, x + 240, 200, true );

for ( var y: Number = -240; y < layerManager.height; y += layerManager.height / 50 )
Drawing.drawLine( layerManager.backgroundImage, 0x80888800, 0, y, 700, y + 240, true );

new GaussianNoise( .16, true ).apply( backGround );

layerManager.addLayer( new Layer( text, 1, BlendMode.ADD ) );
layerManager.addLayer( new Layer( textGlow, 1, BlendMode.ADD, -5, -5 ) );
layerManager.addLayer( new Layer( textGlow, 1, BlendMode.ADD, 5, 5 ) );

var pixelate: Pixelate = new Pixelate( 3 );
pixelate.apply( text );
pixelate.apply( textGlow );

layerManager.merge();
textGlow.dispose();
text.dispose();

layerManager.backgroundImage.updateHistogram();

var histoGram: Image = Image.fromBitmapData( layerManager.backgroundImage.histogram.getBitmapData( 700, 400 ), ImageFormat.RGB );

layerManager.addLayer( new Layer( histoGram, 1, BlendMode.ADD, 0, -200 ) );

layerManager.merge();

histoGram.dispose();

new ContrastCorrection( 1.4 ).apply( layerManager.backgroundImage );
new LevelsCorrection().apply( layerManager.backgroundImage );

addChild( new Bitmap( layerManager.bitmapData ) );[/as]
