IG_DIB_channel_depths

This function copies channel bit depths to an array.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_DIB_channel_depths_get( HIGDIBINFO hDIB, AT_INT ChannelCount, AT_INT* lpChannelDepths );

Arguments:

Name	Type	Description
hDIB	HIGDIBINFO	DIB info handle.
ChannelCount	AT_INT	Number of channels for which to return depths.
lpChannelDepths	AT_INT*	Array to which to copy channel depths.

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 Professional.

Example:

	Copy Code
AT_ERRCOUNT nErrcount; /* Number of errors on stack / HIGDIBINFO hDIBInfo; / DIB info handle / HIGEAR hImage; / HIGEAR handle of image / AT_INT nChannels; / Number of channels in image / LPAT_INT depths; / Array of channel depths / nErrcount = IG_image_DIB_info_get(hImage, &hDIBInfo); nChannels = IG_DIB_channel_count_get(hDIBInfo); depths = (LPAT_INT) malloc(nChannels sizeof(AT_INT)); nErrcount = IG_DIB_channel_depths_get(hDIBInfo, nChannels, depths);

Copy Code

AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGDIBINFO hDIBInfo;    /* DIB info handle */
HIGEAR hImage;          /* HIGEAR handle of image */
AT_INT nChannels;       /* Number of channels in image */
LPAT_INT depths;        /* Array of channel depths */
nErrcount = IG_image_DIB_info_get(hImage, &hDIBInfo);
nChannels = IG_DIB_channel_count_get(hDIBInfo);
depths = (LPAT_INT) malloc(nChannels * sizeof(AT_INT));
nErrcount = IG_DIB_channel_depths_get(hDIBInfo, nChannels, depths);

Remarks:

You can use this function to find out the bit depths of each individual channel.
