A simple solution for encoding common icon file-formats, such as .ico and .icns.
This crate is mostly a wrapper for other libraries, unifying existing APIs into a single, cohesive interface. It serves as IconPie's internal library.
An icon consists of a set of entries. An entry is simply an image that has a particular size. IconBaker simply automates the process of re-scaling pictures and combining them into an icon.
Pictures are scaled using resampling filters, which are represented by functions that take a source image and a size and return a re-scaled image.
This allows the users of this crate to provide their custom resampling filters. Common resampling
filters are provided in the
resample module.
```rust use icon_baker::*;
fn example() -> icon_baker::Result<()> { let icon = Ico::new();
match SourceImage::from_path("image.svg") {
Some(img) => icon.add_entry(resample::linear, &img, 32),
None => Ok(())
}
} ```
```rust use icon_baker::*; use std::{io, fs::File};
fn example() -> io::Result<()> { let icon = PngSequence::new();
/* Process the icon */
let file = File::create("out.icns")?;
icon.write(file)
} ```
This are the output formats IconBaker nativally supports. Be aware that custum output types can
be created using the Icon trait.
icoicnspng sequence (tar)Icon Baker uses the icns crate for generating .icns files. The
supported icon types are specified
by the creators of such crate as follows:

IconBaker uses image for raster graphics manipulations and
resvg with the raqote
backend for svg rasterization. Note that raqote requires cmake to build.

| jpeg | Baseline and progressive |
| gif | Yes |
| bmp | Yes |
| ico | Yes |
| tiff | Baseline(no fax support), lzw, PackBits |
| webp | Lossy(Luma channel only) |
| pnm | pbm, pgm, ppm, standard pma |
