GDI+ stretch draw


    I'm working with large tiff images and I found that GDI+ supports
loading G4 compressed tiff's which is great. But the problem is that images
are about 2400x3300 and drawing images to screen is slow since GDI+ does
some pixel-combining (cubic,...) when shrinking image which I don't need. I
would like it to delete scan lines not combine them. I tried to specify low
quality mode but same results. Does anyone know how to accomplish this (turn
off all extra processing to gain as much speed as I can)?
