Usage

There are two ways to use this app:

• GUI
• CLI

GUI

Run the application

./prismatica

Choose a file you want to upload, pick the palette and press Generate From there you can pick what palette of the theme you want, in each tab all the listed images are of different noise levels. Choose which you find best and press download, the image will then automatically be downloaded to the directory you ran the application. Press view to full screen the image to get a better look

CLI

Run the CLI with the path to the input image, the theme, the palette and the noise level

./prismatica path/to/image.png -t catppuccin -p mocha -n 2

This will create a file mocha-image.png for your converted image

Issues

• Downloading will put file in current dir, if run through a launcher this may be awkward.

Show directory picker?

• Download crashes AppImage

AppImage needs file picker, will also resolve previous issue

• ~~Switching between tabs quickly causes too many requests to backend and may crash your app.

No way to cancel promises, may switch multithreading completely to backend~~
Fixed w/ job pooling and caching

• Possible memory leak?

  • Rust - Fixed, rewrote image processing handlers, previously would quickly climb to OOM
  • Front end - WebKit View holds a lot of memory for some reason, may be issue with tarui IPC

• ~~Switching tabs doesn't cache previous images, will re-generate

Cache these on either frontend or backend~~
Fixed, added caching on front end

Todo

• Fix all issues
• Add more palettes
  • Rose pine
