Upscayl NCNN has received the hotfix. If you want to fix it in Upscayl right now, here's what you can do:

1. Download the latest upscayl-bin: https://github.com/upscayl/upscayl-ncnn/releases/tag/20240426-231028 and extract it somewhere. It should have a file called 'upscayl-bin'.
2. Find where Upscayl is installed on your system. Find the folder called 'resources' which should have a 'bin' folder. For Mac, it would be in /Applications/Upscayl.app/Contents/Resources/bin´

3. Replace the 'upscayl-bin' file with the one you just downloaded in Step 1.

This should hopefully fix all issues with the custom width 😄

@NayamAmarshe

The hotfix works well on Windows 11 23H2.
Thank you for your hard work.

from upscayl.

Since the hotfix works, we should probably release a 2.11.1.

Ok, will do!

Followup: Now when I try to rescale without custom settings I get a corrupted output:

Reinstalling 2.10 once again cleared the issue.

from upscayl.

Seems like there's an issue with height calculation.

It's calculating the height as 1020x1465275732, which is why it's unable to write.

from upscayl.

I'd suggest using just the scale for now. I'll push a new update for custom width later.

from upscayl.

Also strange that it never actually calculates the height, otherwise it would have given an output.

@StScAllen Could you please share the image if possible? I am unable to reproduce the error.

from upscayl.

Absolutely. Image attached.

I started using upscayl today, and I am having the exact same issue. I am trying to increase the image from 870x870 to 4500x4500. (I would share the image but my company won't allow it.) I'm glad there is an update planned to fix it, thanks.

FYI - If you uninstall 2.11 and download and install 2.10 it will work fine. Nice changes in 2.11 but rolling back to 2.10 is not critical.

Understood. Thank you for the tips.

@StScAllen I'm unable to reproduce this issue on Mac:

from upscayl.

Huh, on Linux it throws an error. It's calculating the wrong height.
So the issue is on Linux and Windows.

from upscayl.

@aaronliu0130 the images don't stretch, they get corrupted. It takes int's upper value as the height for some strange reason.

from upscayl.

That may be the cause, but the visual effect in #794 (comment) (and in my testing) is that the image gets striated and stretched to the right.

from upscayl.

Windows 11 23H2
Upscayl 2.11.0

There are 2 symptoms.
--> no output
--> distorted

source

512x512

width:1200, fast real-esrgan --> no output

width:1200, remarci --> distorted

not 1200x1200

from upscayl.

Hi,

I just wanted to confirm what xvim64 commented. Either no output or distorded. The height is wrong. A 768x768 image that I try to upscale to 4k is becoming a 4096x628. ;-(

Just wanted to say that your program is still really nice though. Having the custom width working would be so sweeeeeet!

from upscayl.

This should hopefully fix all issues with the custom width 😄

Legendary. Just confirming it's also fixed a bug for me where custom width images weren't saving. Now custom width images are working as expected. Thank you so much <3
