stream for large images
Posted: 2007-06-20T23:33:35-07:00
I'm using q8. I've decided that I need to split up my image into sections i can put them in memory. I understand that for large images stream -extract is the way to go. I think my problem is that I don't understand the raw format that this creates. Here's what I'm working with. I've got a 24197x17039 .BMP that I'd like to split into, say, 16 pieces. So for the just the first one I do
stream -monitor -verbose plains05.bmp -extract 6050x4260 p000.bmp
and duly get a p000.bmp. The problem is that it's 1.15GB, exactly the same as plains05.bmp! Why isn't it smaller, what's going on?
