Summary	0005970: TIFF does not read 48bit images
Description	hi, we have found a problem in 48 bit tiff image loading we have used this workaround in TIFFImageIO::EvaluateImageAt( void* out, void* in ) ... case TIFFImageIO::RGB_: if(m_ComponentType == USHORT) { unsigned short image_us = (unsigned short)out; unsigned short source_us = (unsigned short)in; red = (source_us); green = (source_us+1); blue = (source_us+2); (image_us) = red; (image_us+1) = green; (image_us+2) = blue; if ( m_InternalImage->SamplesPerPixel == 4 ) { alpha = (source_us+3); (image_us+3) = 65535-alpha; } } else { red = (source); green = (source+1); blue = (source+2); (image) = red; (image+1) = green; (image+2) = blue; if ( m_InternalImage->SamplesPerPixel == 4 ) { alpha = (source+3); (image+3) = 255-alpha; } } increment = m_InternalImage->SamplesPerPixel; break; ... best regards, Mazzetto Manuel, Rizzi Davide
Steps To Reproduce	User supplied a sample file that contained 48 bits per pixel. Ran with itkTIFFImageIOTest. Resulting image was garbage.
