[Development] Implementation of QML Canvas

[Helmut Mülner]

Hi!

 

By stumbling over an out-of-memory problem in my application, I found out
about the implementation of the QML Canvas item: It uses 2 QImages as
internal buffers and uses QPainter to write into this buffer. (I also
reported https://bugreports.qt-project.org/browse/QTBUG-41657 )

 

Are there any plans to change this implementation and use OpenGl or the
scene graph more directly to improve performance and reduced the memory
footprint?

 

Best regards,

 

Helmut
