A utility for storing, accessing and converting colors in a BGRA (blue, green, red, alpha) color format.
var color:BGRA = 0x003388FF;
trace (color.b); // 0x00
trace (color.g); // 0x33
trace (color.r); // 0x88
trace (color.a); // 0xFF
var convert:ARGB = color; // 0xFF883300
Constructor
Variables
Methods
inlinemultiplyAlpha ():Void
Multiplies the red, green and blue components by the current alpha component
inlinereadUInt8 (this:UInt, data:UInt8Array, offset:Int, ?format:PixelFormat):Void
Reads a value from a UInt8Array
into the current BGRA
color
Parameters:
data | A |
---|---|
offset | An offset into the |
format | (Optional) The |
premultiplied | (Optional) Whether the data is stored in premultiplied alpha format |
inlineset (this:UInt, b:Int, g:Int, r:Int):Void
Sets the current BGRA
color to new component values
Parameters:
b | The blue component vlaue to set |
---|---|
g | The green component value to set |
r | The red component value to set |
a | The alpha component value to set |
inlineunmultiplyAlpha ():Void

color into a UInt8Array
Parameters:
data | A |
---|---|
offset | An offset into the |
format | (Optional) The |
