Re: Help efficiently build huge image from tiles
I have been trying for hours but can't seem to apply this idea. I think I'm doing a different approach than the one you tried to explain, I have a very limited knowledge of IM. Could you demonstrate a few command line examples to work this out in the way you suggested? Btw, tiles' filenames are ...

Re: Help efficiently build huge image from tiles
I'll try to do this again tomorrow. I tried to apply this logic to a smaller resolution for testing and didn't go as expected. 144 tiles that build to an image of 5888x5888, needs to be 6144x6144 to end up with 64 tiles of 768x768. 768 * 5888 / 6144 = 736 What I am doing now is this: 1. Montage of ...

Re: Help efficiently build huge image from tiles
I'm going to try this something like that, but first, how did you extrapolate 746?

Re: Help efficiently build huge image from tiles
Let's imagine this square image, for example: 428|256|296|512 256|428|512|296 296|512|256|428 512|296|428|256 This square is composed by 16 tiles, and I need them converted in a way so that I end up with only 2 tiles of 768. As per the example above, the full image has a resolution of 1492. The way ...

Re: Help efficiently build huge image from tiles
You might buy, beg, steal or borrow an external hard drive. If the inputs are all 8 bits/channel/pixel, Q8 will do fine. Perhaps you can do the job in pieces, eg build a quarter of the 95488x95488 image, then resize that and divide into the final tiles. Then do the next quarter. Or do the job in ...

Help efficiently build huge image from tiles
Hello, I'm trying to build a really big image from 34.969 tiles, the bigger tiles are at 512x512 each, and the target image will be 95488x95488 pixels. The reason why I need to build such a big image is because afterwards I need to resize it and then crop it into multiple tiles once again, because ...
