A simple 2D graphics library for C++.

• Documentation

• a function tint() that allows to tint images.
• the function noTint().
• tint example.
• a cmake option to disable building the examples.

• overloaded function image() that allows to display subimages which could be very useful for spritesheets and animations.
• the function imageMode().
• spritesheet example.

• the function loadImage() to return nullptr and print an error message if anything went wrong loading the image.
• the documentation by overhauling the section "Outline" and "Image".

• support for custom shaders and renderpasses.
• several new examples, showcasing the capabilities of renderpasses.

• the way how stuff is rendered, allowing deferred rendering techniques.
• the attributes of Shape, i.e. removal of obsolete color attribute.
• the function signature of image().
• the default shader, i.e. refactored the image() related glsl code into a seperate shader.

• default background color not being applied.

• display density to be considered when rendering text.

• support for text rendering.

• the way shaders are handled.

• Quadtree example.

• the way memory is allocated for the settings stack.

• point() not being affected by strokeWeight().

• namespace xd.
• a small program that can be used to embed text-based resource files into headers.
• install targets.
• package targets.
• releases for Linux, macOS and Windows.

• shader version to GLSL 3.30.
• include directory folder structure.
• the way how shaders are loaded.
• the libxd logo.
• the documentation.

• the possibility to define key event callbacks using the functions keyPressed() and keyReleased().
• keyboard interaction example.

• the documentation.
• some cmake build scripts.

• the possibility to define mouse event callbacks using the functions mouseMoved(), mousePressed(), mouseReleased() and mouseWheel().
• mouse interaction example.
• Google Analytics.

• the location of include/stb_image.h to lib/stb/stb_image.h.
• the documentation.
• some cmake build scripts.

• the lib folder being wrongly identified as a first party source folder by github's linguist.

This is the start of libxd as a remote repository. Prior to publishing libxd to github goes about 2 months of local development. These are rudimentary changelogs from the time before github:

• the functions setup(), draw() and destroy() using forward declaration.
• global variables width, height to retrieve the current width and height.
• shape functions: ellipse(), line(), point(), rect(), triangle().
• vertex, geometry and fragment shaders which contain e.g. the logic that allows to draw outlined shapes in a single render cycle.
• drawing style functions: background(), clear(), ellipseMode(), fill(), noFill(), noStroke(), rectMode(), stroke(), strokeWeight().
• support of alpha channel for functions that deal with colors.
• transformation functions: applyMatrix(), resetMatrix(), rotate(), scale(), translate().
• constants: HALF_PI, PI, QUARTER_PI, TWO_PI.
• the functions push() and pop() which allow the current drawing style settings and matrix transformations to be temporarily saved on a stack.
• the possibility to directly modify window pixels using the global variable pixels.
• support for image loading.
• the possibility to directly modify image pixels using the member variable Image::pixels.
• convenience functions like: millis(), random(), randomSeed().
• functions that allow to alter the control flow: loop(), noLoop().
• a function redraw() that ought to be used in conjunction with noLoop.
• libraries: glad, glfw, glm, stb_image.
• a docsify documentation.
• cmake build scripts.
• fireworks example.
