Methods
Static methods
staticaverage (image:Bitmap, ?region:Rectangle, ?alpha:Int):Color
Computes the average RGB color of the pixels in the image.
Parameters:
image | The image whose average color will be calculated. |
|---|---|
alpha | The opacity of the image (0-255), defaults to opaque (255). |
Returns:
The average RGB color of the image, RGBA8888 format. Alpha defaults to opaque (255).
staticinlineblendColors (c1:Color, c2:Color, ?blend:ColorBlend):Color
Applies a linear transformation (a * value + c) on each channel (red, green, blue, alpha) .
staticinlinefilter (c:Color, o:ColorFilter):Color
Supports filter declarations by providing a function fn that transform colors to colors, or if not given, alternatively it supports providing 1-grade equation coeficients to transform each channel linearly (red*a+c).
