ICC (International Color Consortium) Profiles allow for consistent color in images when scanning, displaying, and printing. RasterMaster for Windows imaging SDK gives developers the ability to apply ICC profiles to color images. These profiles can be applied to an image when viewing or printing. They can also be applied to an image permanently.
This tech tip shows how to apply an ICC Profile when printing an image.
int ApplyDestinationProfile()
{
CString szFileName; // image file name
CString szDestinationProfileName; // destination profile name
char* pDestinationProfileBuffer; // destination profile buffer
int nImageHandle; // image handle
int nStatus; // return status
// setup output profile
// set destination profile name to valid output (printer) profile
szDestinationProfileName = “C:\\windows\\system32\\outputdevice.icc”;
// open destination profile for reading
CFile destProfile( szDestinationProfileName, CFile::modeRead );
// allocate buffer for output profile
pDestinationProfileBuffer = new char[ destProfile.GetLength() + 1 ];
// clear output profile buffer
memset( pDestinationProfileBuffer, 0, destProfile.GetLength() + 1 );
// read in output profile from file into buffer
destProfile.Read( pDestinationProfileBuffer, destProfile.GetLength() );
// close file
destProfile.Close();
// get handle to image file
szFileName = “C:\\Image.tif”;
nImageHandle = IMG_decompress_bitmap_page( ( char*)(LPCTSTR)szFileName, 0 );
// now apply output profile to image when printing
if ( NULL != pDestinationProfileBuffer )
{
int nStatus =
IMG_apply_profile( m_nImageHandle, // handle to image
NULL, // use default input profile
pDestinationProfileBuffer, // profile buffer
2 // apply when printing
);
}
// free up allocated memory
if ( NULL != pDestinationProfileBuffer )
delete [] pDestinationProfileBuffer;
return nStatus;
}
