Hi All,
Is there a way to load a 16 bits per colour channel Tiff file so that the full 16 bits can be accessed? Using StreamRaster::LoadFileAny
Thank you.
Regards,
Tim

Hi Tim
It is a general property of libtiff that it returns 8bit samples. Also, the whole U++ interface uses 8bits per color, so it would be difficult to fit it in.
According to this mailing list however, you can access the 16bit values using other APIs such as TIFFReadScanline, TIFFReadEncodedStrip or TIFFReadTile. Those should be available in U++ in plugin/tif you will probably just have to include some additional header or declare the functions in your code. There are some relevant examples at http://www.libtiff.org/libtiff.html that look quite promising.
Best regards,
Honza

Hi Honza,
Thanks for the quick response. I will look into the TIFFReadScanline and TIFFReadTile functions. The libtiff link looks quite usefull.

Hello Tim,
Did you resolve with 16bit tif image?
Have you an example with U++?
Thank you in advance!
