Member Function Documentation

◆ blitFromMemory()

void Ogre::GL3PlusHardwarePixelBuffer::blitFromMemory	(	const PixelBox &	src,
		const Box &	dstBox
	)

virtual

Copies a region from normal memory to a region of this pixelbuffer.

The source image can be in any pixel format supported by OGRE, and in any size.

Parameters

src	PixelBox containing the source pixels and format in memory
dstBox	Box describing the destination region in this buffer

Remarks: The source and destination regions dimensions don't have to match, in which case scaling is done. This scaling is generally done using a bilinear filter in hardware, but it is faster to pass the source image in the right dimensions.
