4. Defining Colors
• A color is stored as an unsigned integer
• A color is composed by 24 OR 32 bits (8
bit a channel)
• A color is computed as a HEX

• Perlin Noise magic

6. Applying Filters
• Filters applied to BitmapData are more
performing but DESTRUCTIVE
• You can apply only BitmapFilters
(BevelFilter, BlurFilter, ColorMatrixFilter, ConvolutionFilter,
DisplacementMapFilter, DropShadowFilter, GlowFilter, GradientBevelFilter,
GradientGlowFilter, ShaderFilter*)
• (take a look at Image Processing library by Joa Ebert)

7. Masking, Detecting
Interacting
• Use BitmapData.threshold() to mask a
color within a bitmapData
• Use BitmapData.getColorBoundsRect() to
locate it
• THEN INTERACT! :D
