GrapeCity.Documents.Imaging.GrayscaleBitmap.ToShadowBitmap

ToShadowBitmap Method

Creates a semi-transparent GcBitmap from the current GrayscaleBitmap.

This method treats the current GrayscaleBitmap as a transparency mask, regardless of the TransparencyMask property value.

public GcBitmap ToShadowBitmap(Color shadowColor, float opacityFactor = 1, bool zeroIsOpaque = false)

Public Function ToShadowBitmap(shadowColor As Color, Optional opacityFactor As Single = 1, Optional zeroIsOpaque As Boolean = False) As GcBitmap

Type	Name	Description
Color	shadowColor	The color to fill opaque pixels of the target bitmap.
float	opacityFactor	Additional factor to scale the alpha channel.
bool	zeroIsOpaque	Specifies whether zero values correspond to fully opaque (true) or fully transparent (false) pixels.

Type	Description
GcBitmap	The newly created GcBitmap.

Converts an existing instance of GcBitmap to a semi-transparent bitmap representing the current GrayscaleBitmap.

This method treats the current GrayscaleBitmap as a transparency mask, regardless of the TransparencyMask property value.

public void ToShadowBitmap(GcBitmap bmp, Color shadowColor, float opacityFactor = 1, bool zeroIsOpaque = false)

Type	Name	Description
GcBitmap	bmp	The target GcBitmap object.
Color	shadowColor	The color to fill opaque pixels of the target bitmap.
float	opacityFactor	Additional factor to scale the alpha channel.
bool	zeroIsOpaque	Specifies whether zero values correspond to fully opaque (true) or fully transparent (false) pixels.
