ImageGear Filter Control Parameters:
Filter Control Parameter | Type | Default Value | Available Values | Description |
ALIGNMENT | UINT | 0 | 0, 1, 2, 4 |
Row 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.
