Namespace

Assembly

PaintDotNet.Windows.dll

CreatePaletteFromBitmap(IBitmapSource, int, bool)

Initializes a palette using a computed optimized values based on the reference bitmap.

IPalette CreatePaletteFromBitmap(IBitmapSource bitmap, int colorCount, bool addTransparentColor)

Parameters

bitmap IBitmapSource

The source bitmap.

colorCount int

The number of colors to initialize the palette with.

addTransparentColor bool

A value to indicate whether to add a transparent color.

Returns

IPalette

Remarks

The resulting palette contains the specified number of colors which best represent the colors present in the bitmap. The algorithm operates on the opaque RGB color value of each pixel in the reference bitmap and hence ignores any alpha values. If a transparent color is required, set the addTransparentColor to true and one fewer optimized color will be computed, reducing the colorCount, and a fully transparent color entry will be added.

This method uses the Median Cut algorithm for palette generation.

This method is a wrapper around IWICPalette::InitializeFromBitmap().
