[Bug]: The grimblast screenshot utility doen't work with KDE Plasma (Wayland)

[rinnarii]

Describe the bug
Script fails to create the files that the terminal output says it did

To Reproduce
Steps to reproduce the behavior:

1. Run ./OCR4Linux.sh
2. Select any language
3. No text went to clipboard

Expected behavior
No clipboard result. Ignore the The script has finished successfully. as it clearly is a default output and the script didn't check for errors properly. Actually, it didn't let me select the area to screenshot

Screenshots
Here's the terminal output instead:

[rinna@latitudee5440 ~/Desktop/OCR4Linux] (main)$ chmod +x OCR4Linux.sh

Additional context
I checked my file manager for /home/rinna/Pictures/screenshots/screenshot_09122025_181637.jpg and /home/rinna/.config/OCR4Linux/output_text.txt and those indeed did not exist.

Hi,

Thanks for the report:)

Can you tell me the following:

1- What distro u are using?
2- u use Plasma KDE with Wayland/X11 or Hyprland?
3- What are the write permissions for the following directories:

a- ~/.config/OCR4Linux
b- ~/Pictures/Screenshots

1- What distro u are using?

Arch Linux, did a yay -Syu just in case but the ./OCR4Linux.sh still failed

2- u use Plasma KDE with Wayland/X11 or Hyprland?

KDE 6.5.3 with Wayland

3- What are the write permissions for the following directories:

a- ~/.config/OCR4Linux

Access: (0755/drwxr-xr-x) Uid: ( 1000/ rinna) Gid: ( 1000/ rinna)

b- ~/Pictures/Screenshots

I just realized that it created a screenshots folder (lowercase s), and I already have an existing Screenshots (capitalized first letter). I moved my existing picture files and deleted both folders just to test. After running the script again, it created a small letter screenshots folder but still failed. Here's the stat output for the newly created one:
Access: (0755/drwxr-xr-x) Uid: ( 1000/ rinna) Gid: ( 1000/ rinna)

Hi,

Sorry for replaying late almost 1 month, but I was slammed at work :)

I did some investigation and found out that grimblast is a helper for screenshots within Hyprland specifically not all Wayland sessions would work, so I am searching for a utility that can be used across all Wayland sessions no matter what the DE is 👍🏿

Is it possible to do a conditional check if ever that you can not find a universal Wayland tool, i.e. if kde == use this, else if hyprland == this other one instead
Also, it might be good practice to catch exceptions for when the file did not exist, as the script output continued as if it worked as intended and reported that it finished successfully.

Actually, I didn't want to go there from the start, but unfortunately, till now, I still haven't found a universal Wayland screenshot utility due to the difference protocols (wlroot, xdg-.... etc..) that are being used by the DEs/WMs.

This solution would be my last resort :)
