You're stressing the limit of my collage maker...
A 105570x66015 RGB image in float32 takes about 77.88GB of memory. Considering that we need to keep both the tiles and the resulting collage in memory, we need double the amount.
At this size, all operations that operate on the collage will be extremely slow. This includes displaying it on GUI, resizing, blending, etc. GPU won't help either, as even Tesla A100 80GB can barely fit one such collage.
Displaying a 77.88GB image will most likely hang the GUI. A potential solution to this is to resize the collage to a reasonable size (say below 10000 pixel wide), and then display it. But the resize operation will be slow too. Let me know what you think.
By the way, given the scale of the problem you're working on, I'm curious about what kind of hardware do you have on your workstation.
