IG_pixel_bits_per_channel

IG_pixel_bits_per_channel_get

In This Topic

This function returns the number of bits (8, 16, or 32) allocated for storing pixel data for a single channel in the given pixel object.

Declaration:

	Copy Code
AT_DEPTH ACCUAPI IG_pixel_bits_per_channel_get(HIGPIXEL hPixel);

Arguments:

Name	Type	Description
hPixel	HIGPIXEL	Handle of pixel object.

Return Value:

Return value is the same for all channels and represents the maximal bit depth aligned to all bytes.

Supported Raster Image Formats:

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

Sample:

None

Example:

	Copy Code
AT_ERRCOUNT nErrcount; /* Number of errors on stack / HIGEAR hImage; / Handle of image / HIGPIXEL hPix; / Handle of pixel / AT_DEPTH bitsPerChan; / Number of bits per channel */ nErrcount = IG_load_file("test.jpg", &hImage); nErrcount = IG_DIB_pix_get(hImage, 0, 0, &hPix); bitsPerChan = IG_pixel_bits_per_channel_get(hPix); IG_pixel_delete(hPix); IG_image_delete(hImage);

Copy Code

AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGEAR hImage;          /* Handle of image */
HIGPIXEL hPix;          /* Handle of pixel */
AT_DEPTH bitsPerChan;   /* Number of bits per channel */
nErrcount = IG_load_file("test.jpg", &hImage);
nErrcount = IG_DIB_pix_get(hImage, 0, 0, &hPix);
bitsPerChan = IG_pixel_bits_per_channel_get(hPix);
IG_pixel_delete(hPix);
IG_image_delete(hImage);
