Aseprite image loader

Overview

Package aseprite implements a decoder for Aseprite sprite files (.ase and .aseprite files).

Layers are flattened, blending modes are applied, and frames are arranged on a single texture atlas. Invisible and reference layers are ignored.

Limitations:

• Tilemaps are not supported.
• External files are not supported.
• Old aseprite format is not supported.
• Color profiles are ignored.

Install

go get -u github.com/askeladdk/aseprite

Quickstart

Use image.Decode to decode an aseprite sprite file to an image.Image:

import (
    _ "github.com/askeladdk/aseprite"
)

img, imgformat, err := image.Decode("test.aseprite")

This is enough to decode single frame images. Multiple frames are arranged as a texture atlas in a single image. Type cast the image to aseprite.Aseprite to access the frame data, as well as other meta data extracted from the sprite file:

if imgformat == "aseprite" {
    sprite := img.(*aseprite.Aseprite)
    for _, frame := range sprite.Frames {
        // etc ...
    }
}

Alternatively, use the Read function to directly decode an image to aseprite.Aseprite:

sprite, err := aseprite.Read(f)

Read the documentation for more information about what meta data is extracted.
