IG_DIB_channel_depth

This function returns the bit depth of the channel specified by the Index parameter.

Declaration:

	Copy Code
AT_INT ACCUAPI IG_DIB_channel_depth_get( HIGDIBINFO hDIB, AT_INT Index );

Arguments:

Name	Type	Description
hDIB	HIGDIBINFO	DIB info handle.
Index	AT_INT	Index of channel of which to return bit depth.

Return Value:

Returns specified channel's bit depth.

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 / HIGDIBINFO hDIBInfo; / DIB info handle / HIGEAR hImage; / HIGEAR handle of image / AT_INT depth; / Returned depth of first channel */ nErrcount = IG_image_DIB_info_get(hImage, &hDIBInfo); depth = IG_DIB_channel_depth_get(hDIBInfo, 0);

Copy Code

AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGDIBINFO hDIBInfo;    /* DIB info handle */
HIGEAR hImage;          /* HIGEAR handle of image */
AT_INT depth;           /* Returned depth of first channel */
nErrcount = IG_image_DIB_info_get(hImage, &hDIBInfo);
depth = IG_DIB_channel_depth_get(hDIBInfo, 0);

Remarks:

For example, if you had a typical 24-bit RGB image with three 8-bit channels, you could specify 0, 1, or 2 for the index and the return value would be 8.
