lib-anim documentation

The lib-anim toolbox aims at using minimal code to leverage the power of Qt and produce smooth animations.

Keep your time for what matters

lib-anim unleashes the power of Qt with minimal effort. The user manages meaningfull objects and variables directly related to the animation like rectangles, positions or colors, and not abstract objects like QGraphicsScene or QInputMethodQueryEvent 😱. In other words, all the complexity of Qt programming is hidden, so you can spend your time on what matters for the final result.

Key features

• Animations are rendered in separate windows with customizable layouts.

• 2D animations are supported.

• Multiple cross-linked animations can be displayed in the same window.

• An information panel can display textual information (html), with live updates.

• Animations can be recorded in movies.
