ImageGear Filter Control Parameters:

Filter Control Parameter	Type	Default Value	Available Values	Description
ALIGNMENT	UINT	0	0, 1, 2, 4	Row alignment. 0: DWORD alignment 1: BYTE alignment 2: WORD alignment 4: DWORD alignment
BITS_PER_PIXEL	UINT	0		Used internally
COMPRESSION	AT_MODE	0		Used internally
FILL_ORDER	INT	0		Used internally
HEIGHT	AT_DIMENSION	0		Used internally
UNCOMPRESSED_PACKED	AT_BOOL	FALSE	FALSE, TRUE	Set to TRUE to read uncompressed packed RAW format, where pixels are not padded to a byte boundary. Set to FALSE to read unpacked format. For example, two 12-bit pixels occupy 3 bytes in the packed format, and 4 bytes in the unpacked format.
WIDTH	AT_DIMENSION	0		Used internally

Comments:

A raw image file contains no header or identifying information. Also, ImageGear can load images of proprietary or unsupported formats as Raw data. Since ImageGear cannot obtain parameters, such as width, height or bits per pixel from the file, the application should specify them. For uncompressed images, ImageGear assumes BMP row order (bottom line goes first). If the RAW image uses the other row order, use IG_IP_flip function to flip it vertically after loading.
