There is an faster version of colorthief Python library, named fast-colorthief written in C++ and uses pybind to bind it as a Python library. From a benchmark presented in README, it says that Fast Colorthief is nearly 15x faster when used with a 1200x1200 pixels image.

Such a boost would be beneficial for more advanced users, like photographers with cameras that can produce in 4K or higher, but it can also benefit users that just want to get color palette quickly from a high-definition photo.

From what I quickly checked, the original and the C++ version have the same function names, and probably also all of the methods, so fast-colorthief should work like a drop-in replacement for original colorthief library.

I would be nice to be able to translate this app into several languages, this would require a .pot file with the translatable strings in the /po directory..

There should be a label inside of the open button, simply saying "Open" to more clearly explain what the button does. Similar thing can also be with the edit button on the Palette page.

I figured out the translation file.po and translated it to hindi but i'm not a developer and don't know how to do pull requests. Can someone help out?

Description

This PR replaces original colorthief library with faster fast-colorthief, written in C++ and adapts Paleta codebase to changes in the new library. It also includes some minor changes, like fix in Flatpak manifest, updated .gitignore and added notes about match...case statements.

Included changes:

* adapt Paleta codebase to the changes in `fast-colorthief` code
* add `numpy` to runtime requirements
* update pypi-dependencies.json
* fix Flatpak manifest unable to find project root directory
* add note about `match...case` statement
* update .gitignore

The current summary "Extract the dominant colors from any image." could be better, it's a bit too long and has a period at the end.

I'd recommend something like "Extract color palettes from images" or "Generate color palettes".

Description

This PR updates paths in translation files to a new ones for Rust modules. Done automatically by using ninja's helper command: ninja -C _builddir paleta-update-po

Included changes:

* rename `simple_row` module to `simple_palette_row`
* update translation files

Description

This PR contains a Paleta codebase refactor and some other miscellaneous changes.

Included changes:

• Refactor Rust modules
• Move Flatpak manifest to build-aux and change a path to point to the root directory
• Add .editorconfig and format some top-level files with it
• Add DOAP metadata (required in GNOME Circle)
• Use action GLib macro instead of gio::ActionEntry::builder function
• Add Ctrl+W shortcut for closing Paleta's window
• Remove color-thief-py from acknowledgements section in About window
• Stop using i18n_f function in some remaining strings and make delete_palette_dialog heading string translatable
• Move most configuration stuff to the main meson.build
• Merge run and setup shell scripts into new local-build.sh
• Update gdk-pixbuf crate to 0.16

Hi! I'd like to create an Italian translation. Is there already someone working on it? Are there any guidelines to follow? Let me know.

PS. Thanks for the great app!

WebP is already immensely popular on the web while AVIF is gaining traction quickly & is already well-supported by every major web browser. JXL (JPEG-XL) is designed to be the successor to JPEG, has been endorsed by companies like Facebook, Adobe, Shopify, & Cloudinary, and is already gaining popularity in professional workflows. All three formats are open source. You can look into them more here: AVIF | WebP | JXL

Thanks so much for the wonderful application, I enjoy your work!

i really like this project. But i noticed that while getting colors from images is easy enough, adding and generating colors is not. I think this project could really benefit from a feature like generating color palettes using color schemes from the colors you already have in your palettes like how coolors.co does it.

Hi! The current UI of Paleta is pretty good, but it has some weak points:

• The initial state seems empty and unwelcoming.
• The main view feels a little clunky/cluttered, and a little out-of-place among other GNOME apps.
• It feels like the app tries to be both a color extractor and palette manager at the same time. Paleta would benefit from focusing on color extracting, which is its core functionality. There are already some very good GNOME apps for palette management. Having a way to store the palettes for later is still useful, though. :grin:

Based on this, I have created a mockup with some design suggestions. I haven't reinvented the wheel, as the sidebar is a really good layout solution, but it has received style changes. I have given the image view some padding to make the it feel more airy.

The biggest design change is probably how the palettes are stored for later. Instead of a separate section with the ability to create custom palettes from scratch and name, this design uses a bookmarking function. This is more in the scope of the app, as the main use case for saving a palette would be to quickly store it for later. Naming, categorizing and editing palettes is a use case that deserves its own app.

I realize that the changes I suggest are really big, but they don't necessarily need to be implemented all at once. If you think some of them are unnecessary / out of scope for the app, you can just implement the things you like. These are just suggestions, after all :smiley:
