This function takes an 8-bit grayscale or color image and converts it to a grayscale image with a bit depth of 16 bpp.

AT_ERRCOUNT ACCUAPI MED_IP_promote_to_16_gray( HIGEAR hIGear,
const UINT iBits,
const UINT iHighBit);
|
|
Arguments:
| hIGear | The HIGEAR handle of the image to be converted. |
| iBits | An integer variable that sets the number of bits that are actually used. The value range is 9 - 16 bits. |
| iHighBit | An integer variable that sets the high bit for the new 16-bit image. The eighth bit of the original 8 bits is positioned here. If the image is saved as a DICOM, this information is saved to the High Bit Data Element (0028,0102). |
Return Value:
Returns the number of ImageGear errors that occurred during the function call.
Supported Raster Image Formats:
Grayscale – 8 bpp.
Remarks:
The original 8-bit image is discarded. All images created by this function have 16-bit pixels, iBits sets the number of bits out of the 16 that are actually used. iHighBit sets the new position among the 16 bits at which the original 8 bits should be positioned.
