Description

Encodes a monochrome image into a file. The raw image data must be passed to the function through the user defined callback function line by line. The file pointer must be positioned before calling this function. The function supports all the standard CCITT compression types and can create uncompressed monochrome images as well.

Parameters

int	nFile	Image file handle.
UINT	wWidth	Width of the image in pixels.
UINT	wHeight	Height of the image in pixels.
DWORD	dwCompression	Compression type. The low order word contains the main type and the high order word contains the additional info.
INT_PTR	lUserData	User defined info. It is passed to the callback function as a third parameter unchanged.
FILLPROC	lpLineFn	Callback function that will pass the raw DIB lines to the function.

Return values

TRUE on success, FALSE if failed. It sets the error flag to TUNKNOWNCOMPRESSION if the compression type of the image is not supported, or to TCOMPRESSIONFAILED if the compression has failed.
