Qt Aseprite Image Plugin

This plugin adds support for reading .ase and .aseprite files images in Qt applications.

Originally developed for Tiled.

How to Compile

Git Checkout

We use Aseprite as a Git submodule. Make sure to update it recursively:

git submodule update --init --recursive

Not all of Aseprite is free software, but this plugin only uses MIT-licensed parts of Aseprite (dio, render and their dependencies doc, fixmath, flic, gfx and base).

Install Dependencies

Install Qt. You can use the Qt Online Installer or any other method.

Install the dependencies for Aseprite.

Configure CMake

In-source builds are disabled by Aseprite, so it is necessary to use a separate build directory:

cmake -B build -DCMAKE_BUILD_TYPE=Release

The Aseprite libraries used by this plugin rely on Zlib, Pixman, FreeType and HarfBuzz. By default the versions from the Aseprite repository will be used, but you can tell CMake to look for system versions instead by adding the following parameters:

-DUSE_SHARED_ZLIB=on \
-DUSE_SHARED_PIXMAN=on \
-DUSE_SHARED_FREETYPE=on \
-DUSE_SHARED_HARFBUZZ=on

If you have Ninja installed, you can add -G Ninja to the CMake command line for automatic parallel builds.

Build and Install

Trigger the build:

cmake --build build --config Release

The plugin will be built in the build directory. You can install it by running:

cmake --install build --config Release

This will install the plugin to the plugins/imageformats directory of the Qt installation. You can also copy the plugin manually to the plugins directory of your application.
