Raster
An image processing library for Rust.
Pre-Alpha Status
Raster is currently in pre-alpha; There will be breaking changes between versions. The API will stabilize once it reaches 0.1.0. From then on it will follow semver.
Documentation
Examples and API are here
Current Features

- clone - Clone an image.
- crop - Crop image with support for textual anchor points and offsets.
- equal - Compares if two images are equal.
- fill - Fill image with color.
- resize_fit - Resize an image to fit within the given width and height.
- resize_fill - Resize image to fill all the space in the given dimension.
- resize_exact - Resize image to exact dimensions ignoring aspect ratio.
- resizeexactwidth - Resize image to exact width.
- resizeexactheight - Resize image to exact height.
- save - Save to raster formats JPEG, PNG, and GIF
- similarity - Compare two images to see how similar they are.
- blur - Blur image using gaussian or box.

Core Principles
- Keep everything simple
- Stick to primitive or simple types if possible, use advance types when neccessary
- Stick to module + functions if possible, no unneccessary abstraction (eg. OOP)
- Speed over abstraction
- Make function names user-friendly by using common or simple English words
- All functions THAT CAN return an error should return the Result type, otherwise return an appropriate type

To Do List
- ~~More examples and add pictures in docs~~
- Implement bicubic interpolation
- Add geometric transformations
- ~~Add filters and convolution~~
- Memory and perf improvements
- Reduce dependency to image decoders/encoders
