CustomFilterBase Constructor

protected:
CustomFilterBase(
	Margins blockMargins, 
	bool wrapBorders, 
	IEnumerable<ColorMode>^ supportedColorModes
)

Parameters

blockMargins

Type: Lumia.Imaging::Margins
Size of the margins needed if the filter wants to sample neighboring pixels around a source pixel. This should be set to the maximum distance the filter will sample away from the source pixel in the left, right, up and down directions. Note that when any margin is is non-zero, the sourcePixelRegion passed to OnProcess(PixelRegion, PixelRegion) will be larger than the targetPixelRegion.

wrapBorders

Type: System::Boolean
If true, and the block margins are non-zero, when processing a block at the edge of an image the pixel data outside the edge of the image will be taken from a mirrored location inside the image. If false, the pixels in the margin will be transparent black.

supportedColorModes

Type: System.Collections.Generic::IEnumerable<ColorMode>
The color modes that the implementation supports. Valid values are Bgra8888 and Ayuv4444.
