QOI (Quite OK Image Format) integration for Godot Engine 4.x.

This is a GDExtension library. Includes precompiled binaries for Windows, Linux, macOS, iOS, Android and Web, but it must compile for each platform which Godot Engine supports.

Godot 3 version

• Fastest encoding and fast decoding (when working with the QOI class in scripts)
• Editor integration (use .qoi as regular textures)
• Cross-platform
• Simple API

• Large file size when working with .qoi files directly (compared to PNG or WebP. more than 2-3 times larger)

Your support adds motivation to develop my public projects.

To download, use the Godot Asset Library or use one of the stable versions from the GitHub Releases page (just download the first archive from the assets, not one of the Source Codes).

By default, after installation, QOI importer and QOI saver will be active.

The importer allows you to import .qoi files and use them as regular textures in your project.

The saver allows you to save Image and Texture2D resources as .qoi files using standard Godot tools.

But if you don't need these integrations and you want to use only the QOI class, then you can disable them in the project settings. These settings are located here: rendering/textures/qoi/*

The entire API is in the QOI class. It can be found in the documentation inside the engine.

# Read the QOI image from file
# @return null or Image
Image read(path : String) static
# Decode the QOI image from an encoded byte array
# @return null or Image
Image decode(data : PackedByteArray) static
# Write the Image as a file in QOI format
# @return code of Error
Error write(path : String, image : Image) static
# Encode the Image in QOI format as an array of bytes
# @return an array of bytes. If an error occurs, it is empty.
PackedByteArray encode(image : Image) static

func example():
	QOI.write("user://example.qoi", load("res://icon.svg").get_image())
	var img = QOI.read("user://example.qoi")
	var enc = QOI.encode(img)
	var dec = QOI.decode(enc)
	
	var tex: = ImageTexture.create_from_image(dec)
	$TextureRect.texture = tex
