Hi,
I was interested to know how gfl represents particularly binary images. IM represents all images with either 40 (Q8) or 80 (Q16) bits... needless to say it is a complete dog with large images. Resizing an A0 takes upto an hour! Some toolkits can use a single bit (apparently...) for binary images, making memory not really an issue. What is the story with the gfl?
Cheers
Antoine

GFL use 1 bit for binary images, and 8bits for greyscale
