|---|---|
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 Professional.
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. |
