Pix Image Viewer

Explore thousands of images in a zoomable and pannable grid.

Heavily inspired by Galapix but without the segfaults.

Installing

You'll need the Rust package manager cargo which can be installed by https://rustup.rs/ or your distributions package management system.

The crate is published (occasionally) to https://crates.io/crates/pix-image-viewer and can be installed with:

cargo install pix-image-viewer

Or from github head:

cargo install --git=https://github.com/google/pix-image-viewer.git

Or from within the source directory:

cargo install --path=.

Controls

Mouse

| Button | Action | | ------ | ------ | | Left/Right | Zoom in/out. | | Middle | Press and move to pan. |

Keyboard

| Key | Action | | ------ | ------ | | Up/Down/Left/Right | Move the viewport. | | PageUp/PageDown | Zoom in/out. | | T | Toggle panning mode (capture the mouse & cursor moves the viewport). | | F | Toggle fullscreen mode. | | Shift | Hold to zoom and pan in larger increments. |

Limitations

• SledDB only allows a single process to manage the database at a time. Due to this only a single instance can run at a time per database path. A simple workaround could be to use ephemeral --db_path=... locations.

Tech

• Rust stable.
• Sled for the image thumbnail cache.
• Piston game framework + OpenGL.
• Rust image decoding/resizing.

Future direction

• Vulkan or gfx-rs? Allows more work off the render & event handling thread.
• Efficient handling of large images? Tiling? [DONE]
• Efficient handling of millions of small images?
• Sort images by directory/size/time?
• Cluster images by directory/size/time?
• Image curation commands (delete, select, etc)?
• Seamless image loading/fetching/thumbnailing. [DONE]
• Command-line thumbnailing mode?
• Push more magic numbers / consts into flags.
• Selecting image(s).
• Running commands on selected image(s).

And there are many TODOs in the code itself.

Developing

Please use the provided pre-commit hook to keep source code rustfmt clean and the tests passing on rust stable.

Naming conflict

I'm now aware of a naming conflict with https://github.com/linuxmint/pix so will likely be renaming the project soon. Ideas welcome!
