need a hint - small pixel animations

Marcin456

hello everyone,
as a beginner i'm looking for a hint - i need to create few basic animations (12x12 pixels, square) like rotating rainbow or else.
is there any library, or class i should start? i prefer to generate animation "on the fly" rather that load .gif image.
I need alsoe to read pixel by pixel from generated image ...

thanks for any support

Hi @Marcin456

I think that you are look for the animation framework

http://doc.qt.io/qt-5/animation-overview.html

http://doc.qt.io/qt-5/qml-qtquick-animation.html

If you can use QML , the qml book can be a good start,

Hope this can help,

Best regards !

Hi @Marcin456 to be honest , i don't know how to create this kind of effect only with qt/qml,

But i think that this effect can be possible with shader,

If you have knowledge on Fragment Shader programming ,you can mix QML/GLSL to make such effect :

In the following site you can have an idea about what we can do with shader
