    IG_image_bits_per_channel_get
    In This Topic

    This function gets the number of bits allocated for each pixel channel in an image: 8, 16, or 32.

    Declaration:

     
    Copy Code 
    AT_ERRCOUNT ACCUAPI IG_image_bits_per_channel_get(
        HIGEAR hIGear, 
        AT_INT* lpBitsPerChannel 
);

    Arguments:

    Name Type Description
    hIGear HIGEAR HIGEAR handle of image.
    lpBitsPerChannel AT_INT* Returned number of allocated bits for each pixel channel.

    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++.

    Sample:

    Pixel Access

    Example:

     
    Copy Code 
    AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGEAR hImage;          /* Handle of image */
AT_INT nBits;           /* Number of bits per channel */
nErrcount = IG_image_bits_per_channel_get(hImage, &nBits);

    Remarks:

    This is not the same as the bit depth of a channel. The number of bits used for a pixel channel may be less than the number of bits allocated.
