IG_DIB_legacy_bit_depth

This function returns the bit depth that earlier ImageGear versions used to store this image.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_DIB_legacy_bit_depth_get( HIGEAR hIGear, LPAT_INT lpBitsPerPixel );

Arguments:

Name	Type	Description
hIGear	HIGEAR	HIGEAR handle of image.
lpBitsPerPixel	LPAT_INT	Returned legacy bit depth of the image.

Return Value:

Returns the number of ImageGear errors that occurred during this function call. If there are no errors, the return value is IGE_SUCCESS.

Supported Raster Image Formats:

All pixel formats supported by ImageGear for C and C++.

Example:

	Copy Code
AT_ERRCOUNT nErrcount; /* Number of errors on stack / HIGEAR hImage; / Handle of image / AT_INT bpp; / Image bit depth / nErrcount = IG_DIB_legacy_bit_depth_get(hImage, &bpp); / bpp could be 1, 4, 8, 9-16, 24, or 32 */

Copy Code

AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGEAR hImage;          /* Handle of image */
AT_INT bpp;             /* Image bit depth */
nErrcount = IG_DIB_legacy_bit_depth_get(hImage, &bpp);
/* bpp could be 1, 4, 8, 9-16, 24, or 32 */

Remarks:

This function can be used for working with pixel access functions in the legacy mode.
