Loupe is GNOME's default Image Viewer. This fork adds image annotation support.
|
|
|
|
|
|
## Technical Details
|
|
|
|
- Fast GPU-accelerated image rendering with tiled rendering for SVGs
|
|
- Extendable and sandboxed image decoding via [glycin](https://gnome.pages.gitlab.gnome.org/glycin/)
|
|
- Support for more than 15 image formats by default
|
|
- Editing with crop, rotate, and flip for PNG and JPEG
|
|
- **Image annotation** with freeform pen, rectangle, ellipse, triangle, and star tools
|
|
- Extensive support for touchpad and touchscreen gestures
|
|
- Accessible presentation of the most important metadata
|
|
- Sleek but powerful interface developed in conjunction with GNOME Human Interface Guidelines
|
|

|
|
|
|
## Nix
|
|
|
|
With Nix flakes enabled, run the app from a checkout with `nix run .` or install
|
|
it with `nix profile install .`. The flake provides packages for x86_64-linux and
|
|
aarch64-linux. Image loading uses the glycin loaders included by the package.
|
|
|
|
## Supported Image Formats
|
|
|
|
Image Viewer uses [glycin](https://gitlab.gnome.org/GNOME/glycin) for loading images. You can check [glycin's README](https://gitlab.gnome.org/GNOME/glycin#supported-image-formats) for more details about the formats supported by the default loaders. However, glycin supports adding loaders for additional formats. Therefore, the supported formats on your system may vary and might be changed by installing or removing glycin loaders.
