IDXARGBReadWritePtr Members

Description

PackAndMove

Places a buffer of ARGB32 samples into the output surface and moves the sample pointer.

PackPremultAndMove

Places a buffer of ARGB32 samples into the output surfaces and moves the sample pointer.

PackRect

Accepts a buffer of either PMARGB32 or ARGB32 samples and writes them to a subsection of the output surface defined by a DXPACKEDRECTDESC structure.

CopyAndMoveBoth

Copies the specified number of samples from the current position of the source surface to the current position of the output surface.

CopyRect

Copies the specified number of samples from the specified rectangle in the source surface to the current position on the output surface.

FillAndMove

Fills the output surface with the specified sample value, starting at the current position and advancing the current position.

FillRect

Fills a rectangle with the sample value, optionally doing an alpha-blend with the destination.

OverSample

Alpha-blends the sample value over the sample at the specified position.

OverArrayAndMove

Alpha-blends an array of samples over the output surface and moves the pointer a specified number of samples.
