Qt enables combining performance and productivity in hardware-accelerated 2D rendering. This quick video shows some of the possibilities you have with Qt's imperative 2D painting.

Qt Canvas Painter is a compact API that generally follows the HTML Canvas 2D context. Thanks to GPU-acceleration, it provides maximum performance especially on mobile and embedded devices, while allowing for high productivity and enabling:
Adjustable antialiasing
Box gradients and shadows
Grid patterns
Custom shader brushing
Color effects
Painter paths
And more!

Try it out yourself! Check the Canvas Painter example in your IDE in the standard Qt packages, or in Qt Creator, go to Examples and search for canvas painter.
