C# Class Duality.ExtMethodsBitmap

Provides extension methods for Bitmaps.

Public Methods

Method	Description
Crop ( this bm, bool cropX = true, bool cropY = true ) : Bitmap	Creates a cropped version of the specified Bitmap, removing transparent / empty border areas.
GetAverageColor ( this bm, bool weightTransparent = true ) : ColorRgba	Determines the average color of a Bitmap.
GetPixelDataIntArgb ( this bm ) : int[]	Extracts a Bitmaps pixel data as (signed) IntArgb values.
GetPixelDataRgba ( this bm ) : ColorRgba[]	Extracts a Bitmaps pixel data.
OpaqueBounds ( this bm ) : Rectangle	Measures the bounding rectangle of the opaque pixels in a Bitmap.
Rescale ( this bm, int w, int h, InterpolationMode mode = InterpolationMode.Bilinear ) : Bitmap	Creates a rescaled version of a Bitmap.
Resize ( this bm, int w, int h, Alignment origin = Alignment.TopLeft ) : Bitmap	Creates a resized version of a Bitmap. Gained space will be empty, lost space will crop the image.
SetPixelDataIntArgb ( this bm, int pixelData ) : void	Replaces a Bitmaps pixel data.
SetPixelDataRgba ( this bm, ColorRgba pixelData ) : void	Replaces a Bitmaps pixel data.
SetPixelDataRgba ( this bm, byte pixelData ) : void	Replaces a Bitmaps pixel data.
SubImage ( this bm, System.Drawing.Rect rect ) : Bitmap	Extracts a rectangular portion of the original image.
SubImage ( this bm, Rectangle rect ) : Bitmap	Extracts a rectangular portion of the original image.
SubImage ( this bm, int x, int y, int w, int h ) : Bitmap	Extracts a rectangular portion of the original image.

Creates a cropped version of the specified Bitmap, removing transparent / empty border areas.

public static Crop ( this bm, bool cropX = true, bool cropY = true ) : Bitmap
bm	this	The original Bitmap.
cropX	bool	Whether the image should be cropped in X-direction
cropY	bool	Whether the image should be cropped in Y-direction
return	System.Drawing.Bitmap

Determines the average color of a Bitmap.

public static GetAverageColor ( this bm, bool weightTransparent = true ) : ColorRgba
bm	this
weightTransparent	bool	If true, the alpha value weights a pixels color value.
return	ColorRgba

Extracts a Bitmaps pixel data as (signed) IntArgb values.

public static GetPixelDataIntArgb ( this bm ) : int[]
bm	this
return	int[]

Extracts a Bitmaps pixel data.

public static GetPixelDataRgba ( this bm ) : ColorRgba[]
