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

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

Arguments:

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.
