Constructor & Destructor Documentation

◆ RasterImage() [1/3]

VectSharp.RasterImage.RasterImage	(	IntPtr	pixelData,
		int	width,
		int	height,
		bool	hasAlpha,
		bool	interpolate
	)

Creates a new RasterImage instance from the specified pixel data in RGB or RGBA format.

Parameters

pixelData	The address of the image pixel data in RGB or RGBA format.
width	The width in pixels of the image.
height	The height in pixels of the image.
hasAlpha	true if the image is in RGBA format, false if it is in RGB format.
interpolate	Whether the image should be interpolated when it is resized.

Definition at line 172 of file RasterImage.cs.

◆ RasterImage() [2/3]

VectSharp.RasterImage.RasterImage	(	ref DisposableIntPtr	pixelData,
		int	width,
		int	height,
		bool	hasAlpha,
		bool	interpolate
	)

Creates a new RasterImage instance from the specified pixel data in RGB or RGBA format.

Parameters

pixelData	The address of the image pixel data in RGB or RGBA format wrapped in a DisposableIntPtr. The RasterImage will take ownership of this memory.
width	The width in pixels of the image.
height	The height in pixels of the image.
hasAlpha	true if the image is in RGBA format, false if it is in RGB format.
interpolate	Whether the image should be interpolated when it is resized.

Definition at line 190 of file RasterImage.cs.

◆ RasterImage() [3/3]

VectSharp.RasterImage.RasterImage	(	byte[]	data,
		int	width,
		int	height,
		PixelFormats	pixelFormat,
		bool	interpolate
	)

Creates a new RasterImage instance copying the specified pixel data.

Parameters

data	The image pixel data that will be copied.
width	The width in pixels of the image.
height	The height in pixels of the image.
pixelFormat	The format of the pixel data.
interpolate	Whether the image should be interpolated when it is resized.
