    IG_DIB_legacy_bit_depth_get
    In This Topic

    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++.

    Sample:

    Pixel Access

    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 */
    

    Remarks:

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