ios2android

A simple script to port iOS retina images to the appropriate Android density buckets.

Porting an iOS application to Android is a time-consuming task, especially when you have to manually resize 1000 images from iPhone/iPad dimensions to Android density buckets and screen sizes. This script aims to save as much time as possible by automatically resizing these images for you.

Prerequisites

ImageMagick

On Mac OS X, the easiest way to install ImageMagick is with Homebrew:

brew install imagemagick

Usage

1. Put the ios2android bash script somewhere in your path

2. Copy the retina iOS images you want to convert into an empty directory.

3. From a terminal, cd into that directory and run:

$ ios2android

The script will create resized versions of the images and place them into the appropriately named density bucket folders. The script will also compensate for filenames that are not valid in android (such as images starting with numbers or containing hyphens).

Once the script is complete, simply copy the new folders into your Android project and you will have the equivalent of the iOS images. Way easier than manually scaling it yourself!

Example

1. A directory containing the following files:

intro_text@3x.png         (600 x 270 pixels)

will result in:

drawable-mdpi/intro_text.png          (200 x 90 pixels - 33.3%)
drawable-hdpi/intro_text.png          (300 x 135 pixels - 50%)
drawable-xhdpi/intro_text.png         (400 x 180 pixels - 66.6%)
drawable-xxhdpi/intro_text.png        (600 x 270 pixels - 100%)
