Member Function Documentation

virtual void eq::plugin::Compressor::compress	(	const void *const	inData,
		const eq_uint64_t	nPixels,
		const bool	useAlpha
	)

inlinevirtual

Compress data.

Parameters

inData	data to compress.
nPixels	number data to compress.
useAlpha	use alpha channel in compression.

Reimplemented in eq::plugin::CompressorReadDrawPixels, and eq::plugin::CompressorYUV.

Definition at line 72 of file compressor.h.

		void **	out
	)

inlinevirtual

Transfer frame buffer data into main memory.

Parameters

glewContext	the initialized GLEW context describing corresponding to the current OpenGL context.
inDims	the dimensions of the input data (x, w, y, h).
source	texture name to process.
flags	capability flags for the compression (see description).
