Description

〔BlitzLLVM〕 This command does not exist in the original Blitz products. BlitzLLVM adds it.

Sets a pixel of a locked buffer to a color given in the form of WritePixel64. The buffer has to be locked with LockBuffer and the change shows when it is unlocked. This is a BlitzLLVM extension. Writes the color of a pixel of a locked buffer from four half precision floats (Float16), like WritePixel64. The buffer has to be locked with LockBuffer. This is a BlitzLLVM extension.

Differences

• A position outside of the buffer is ignored, and a buffer that is not locked is ignored by a build without -d and stops a debug build (-d) with an error message.
