About

QuickMultiEffect is a Qt Quick component for fast, animated effects. It combines a subset of Qt Graphical Effects (with some extras) into a single item and shader effect. This shader is dynamically created based on which features/effects user enables, to make it always as optimal as possible. QuickMultiEffect is notably more performant than using multiple Qt Graphical Effects when the amount of effects increases.

QuickMultiEffect features

Supported effects that can be freely mixed and matched: * blur * shadow * brightness * contrast * saturation * colorize * mask

Shaders are generated for both Compatibility profile (e.g. OpenGL ES 2.0) and Core profile (OpenGL 3.3+).

QuickMultiEffect component is pure Qt Quick / QML (no C++) which makes it easy to integrate into Qt Quick applications.

The package contains QuickMultiEffect component with API documentation and 4 example applications (Testbed, ItemSwitcher, EffectsBench, QDSTester).

Example applications: * Testbed: Allows testing all features separately or together, while confirming that generated shaders are optimal. Also assists in customizing / extending the shader for specific needs. * EffectsBench: Compares performance of QuickMultiEffect vs. Qt Graphical Effects when the amount of effects is increased. * ItemSwitcher: Presents one example usage for QuickMultiEffect. Allows switching between QtQuick items using a set of fancy animations (Blinds, Thunder, 3DFlip etc.). Based on the examples it is easy to implement own custom switching animations. * QDSTester: Can be used to tweak QuickMultiEffect properties of a simple source item with Qt Design Studio and animate the properties using Qt Design Studio timeline.
