IconPie
A simple command-line tool to generate application icons from raster graphics or vector graphics images.
Quickly combine multiple images and create professional-looking icons for most versions of Windows, macOS, iOS & Linux. Powered by IconBaker.
Features
- Simple interface.
- Sane defaults for the domain of icon composition.
- Supports outputting to
stdout
, allowing for piping. - Available as a single executable.
Overview
An icon consists of a set of entries. An entry is simply an image that has a particular size. For example, this is an icon that has a 32x32 entry, a 64x64 entry and a 128x128 entry:
What does it do?
Notice that, in the example above, most entries are basically the same picture re-scaled to multiple sizes. IconPie simply automates the process of re-scaling the picture and combining those re-scaled entries into an icon.
How does it do it?
Re-scaling
When re-scaling pictures, IconPie preserves their original aspect-ratios. It also ensures that the all re-scaled images are square, by adding transparent borders if necessary. If the picture presents a transparent background, the transparency is preserved in the re-scaled images.
Interpolation
For raster graphics (jpeg
, png
, ...), IconPie uses nearest-neighbor interpolation by default, optimizing for small-resolution images.
Furthermore, when using nearest-neighbor interpolation, it only up-scales images on an integer scale, preserving as much detail as possible.
You can choose to opt-out of the default interpolation scheme for raster graphics by specifying a resampling filter with the -r
flag, as described in the Usage section.
For vector graphics (svg
), IconPie always uses linear interpolation regardless of any specified resampling filter. Vector graphics are also rasterized with antialiasing.
Usage
The formal docopt
syntax for using IconPie is as follows:
icon-pie icns ((-e | --entry) <file path> <size>... [(-r | --resample) (nearest | linear | cubic)])... [(-o | --output) <path>]
icon-pie ico ((-e | --entry) <file path> <size>... [(-r | --resample) (nearest | linear | cubic)])... [(-o | --output) <path>]
icon-pie favicon ((-e | --entry) <file path> <size>... [(-r | --resample) (nearest | linear | cubic)])... [--apple-touch] [--web-app] [(-o --output) <path>]
icon-pie (-h | --help)
icon-pie (-v | --version)
Options
-e FILE (SIZE)...
,--entry FILE (SIZE)...
— Specify an entry's source image and target sizes.-r FILTER
,--resample FILTER
— Specify a re-sampling filter:nearest
,linear
orcubic
. If no filter is specified the app defaults tonearest
.-o PATH
,--output PATH
— Specify an output path. This is optional. If absent the output is directed tostdout
.--apple-touch
— Favicon specific option. Confire the output to include link tags for apple-touch icons in the HTML helper.--web-app
— Favicon specific option. Confire the output to include a.webmanifest
helper for PWA icons.-h
,--help
— Help.-v
,--version
— Display version information.
Examples
Let's say you have the following files saved at your file system.
We'll walk trought some practical examples of IconPie usage.
Simple Usage
Take
big.svg
, resize it to 32x32, 64x64 and 128x128. Then save it aticon.ico
.
$ icon-pie ico -e big.svg 32 64 128 -o icon.ico
Sampling From Multiple Files
Take
small.png
, resize it to 32x32 and 64x64. Then takebig.svg
and resize it 128x128. Then combine the re-scaled entries inicon.icns
.
$ icon-pie icns -e small.png 32 64 -e big.svg 128 -o icon.icns
Specifying a Resampling Filter
Take
small.png
, resize it to 32x32 and 64x64 using linear interpolation. Then takebig.svg
and resize it 128x128. Then combine the re-scaled entries into a favicon scheme.
$ icon-pie favicon -e small.png 64 128 -r linear -o ./favicon/
./favicon/helper.html
<link rel="icon" type="image/png" sizes="64x64" href="icons/favicon-0.png">
<link rel="icon" type="image/png" sizes="128x128" href="icons/favicon-1.png">
