Re: How to handle tifs over 2 GB?

PNG is also limited to 2Gx2G Yes, but I think the file size and the file dimensions have been kinda mixed up here. In theory, the PNG integrer allows files as large as 4.61 Exa-pixels (!) (the 2Gx2G dimension you mentioned) but I'm not sure if there's a proper limit for the file size itself. It see...

This saves memory because it never has to allocate memory for the full-sized image (assuming the "size" is smaller than the original dimensions!). Hi, thanks f...
