Description

Hello,
I was loading a large PNG image and when it was finished I didn't see anything, just white. Also, the image of about 20k x 20k pixels took about 25GB in memory which is quite a lot since an image of size 10k x 10k takes only 2GB then I was expecting to that the larger image would approximately 4 times more...
