Hi, I'm new to this group, also a new user to wintopo - freeware.
My question is about the storage memory error:
I have a pretty big picture where this error occurs. So I tried to see
what the image information says: Memory required to load: 3850MB
Ok, thata a lot. The picture has the size of 47240x47240 px and is only
black an white - 1Bit). In other Programms, like Irfanview it requires
only 266MB.
If I open a file half the size (47240x23620px), both information
Irfanview and wintopo are equal at 133MB required memory to load.
Picture Size 23620x23620px needs 133MB and so on.
Why is the step to the largest picture so big? Are there any
explanations?
Hope you understand my english ;-)
