## Supported Formats
|
|
|
|
Image Viewer uses [glycin](https://gitlab.gnome.org/sophie-h/glycin) for loading images. You can check [glycin's README](https://gitlab.gnome.org/sophie-h/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.

## Building
|
|
|
|
### GNOME Builder
|
|
|
|
GNOME Builder is the environment used for developing this application. It can use Flatpak manifests to create a consistent building and running environment cross-distro. Thus, it is highly
|
|
recommended you use it.
|
|
|
|
1. Download [GNOME Builder](https://flathub.org/apps/details/org.gnome.Builder).
|
|
2. In Builder, click the "Clone Repository" button at the bottom, using `git@ssh.gitlab.gnome.org:GNOME/Incubator/loupe.git`
|
|
or `https://gitlab.gnome.org/GNOME/Incubator/loupe.git` as the URL.
|
|
3. Click the build button at the top once the project is loaded.
|
|
|
|
|
|
## Installation
|
|
|
|
Depending on how you want it installed instructions can differ. If you
|
|
used GNOME Builder to build it, clicking the bar at the top window will
|
|
open a submenu with "Export Bundle". This will create a flatpak bundle,
|
|
which can be installed on any system that supports flatpak.
|
|
|
|
**In order for the Image Viewer flatpak to be able to read the directory images are installed in, you must install a bundle.**
|
|
Once you have a bundle installed, development builds will work properly.
