Android SVG Scripts

Bash scripts to automate and extend the process of using SVG as Android image asset.

This project is also used by DreaminginCodeZH/MaterialColdStart.

Dependencies

  • inkscape: For PNG genration
  • gcalccmd (shsvgdpi.sh): For (friendly) mathematical calculation.

svgdpi.sh

Usage: svgdpi.sh SVG_FILE [DIR_PREFIX [DIR_SUFFIX]]

This script can automatically generate PNG asset of different Dips from SVG arranged properly for direct usage in Android application.

For instance:

./svgdpi.sh path/to/your/file.avg

Will output the following files:

drawable-mdpi/file.png
drawable-hdpi/file.png
drawable-xhdpi/file.png
drawable-xxhdpi/file.png
drawable-xxxhdpi/file.png

You can also add prefix and suffix to the drawable directory name with command line arguments. See the script source for more detail.

shsvgdpi.sh

Usage: shsvgdpi.sh SHSVG_FILE [DIR_PREFIX [DIR_SUFFIX]]

This script implemented a powerful new file format called ShellSVG ( .shsvg), which allows you to embed any shell command/parameter substitution inside your SVG file.

dp (Device-independent Pixel) is supported as an exported function dp(), and mathematical expression is supported as an exported function calc(). You need to wrap dp() inside a calc() if it is used.

This makes drawing Nine-patch bitmaps where the surrounding lines are always 1px while the content must be drawn in dp easy.

What's more, you can now use parameters inside your SVG, a dimension, a color, a filter, everything is OK. Just do it as in shell, for instance ${SOME_PARAMETER}. Parameter definitions can be written in a .conf file which will be source-ed before generation of a standard SVG file, which means this file can have all the shell semantics apart from regular key-value pair, such as source-ing another .conf.

This script has taken rounding on HDPI (with scaling factor 1.5) into account, so that nine-patch bitmaps won't have an anti-aliased border. It is recommended that you call dp() for every single dp dimension separately to avoid accumulated rounding inconsistency.

The usage of this script is just like svgdpi.sh.

For a detailed example, see the sample/ directory.
