A simple command-line tool for generating application icons. Quickly combine multiple images and create professional-looking icons for most versions of Windows, macOS, iOS & Linux.
The formal docopt syntax for using IconPie is as follows:
$ icon-pie ((-e <file path> <size>... [-r (nearest | linear | cubic)])... (-ico | -icns | -png) [<output path>]) | -h | --help | -v | --version
| Flag | Description |
|---|---|
-e <options> |
Specify an entry's options. |
-r <filter> |
Specify a re-sampling filter: nearest, linear or cubic. If no filter is specified the app defaults to nearest. |
-ico [<output path>] |
Outputs to an .ico file. If no output path is specified the app outputs to stdout. |
-icns [<output path>] |
Outputs to an .icns file. If no output path is specified the app outputs to stdout. |
-png [<output path>] |
Outputs a .png sequence as a .tar file. If no output path is specified the app outputs to stdout. |
-h, --help |
Help. |
-v, --version |
Display version information. |
$ icon-pie -e small.svg 16 20 24 -e big.png 32 64 -ico output.ico$ icon-pie -e image.png 32 64 48 -r linear -png output.tar$ echo Here's an ICNS file: ${ icon-pie -e image.jpg 16 32 64 -r cubic -icns | hexdump }

IconPie has two main limitations: both ICNS and SVG are not fully supported. Due to the
use of external dependencies, this app's author is not able to fully support the formal specifications
of those two file formats.
However, the coverage provided by this external dependencies should be enough for most use cases.

IconPie uses the nsvg crate to rasterize .svg files. According to the authors of the crate:
Like NanoSVG, the rasterizer only renders flat filled shapes. It is not particularly fast or accurate, but it is a simple way to bake vector graphics into textures.
The author of icon-pie is inclined to search for alternatives to nsvg if inquired to. Help would be appreciated.
