Hi Developers,
I’m Mattie, a Ph.D. student at the University of Waterloo and I’ve been
studying the code review process of build files in Qt. For example, I’ve found
that changes to build files are 2 to 4 times less likely to be discussed during
code review than changes to source code or test
Ok as far as I can see, this does not have anything to do with image
transformations as such. Using the same transform to to map just a
QRect/QRectF shows the same issue.
As I understand it, the issue here is that when doing perspective
transformation calculations, one needs to know how far
Hi all,
TL;DR: there's a new [[Deprecation]] wiki page, please review.
We noticed recently that some APIs had been wrapped in #if-ery on

The software backend and opengl backend have same as bug, so I think the bug is
not related to scene graphics backend. I conjecture this bug is related to
QQuickRotation::applyTo, It's use the QMatrix4x4::projectedRotate, In
elsewhere, this QMatrix4x4 will be converted to a QTransform, so I star

Interesting. Might be worth checking out if it acts differently between
different scenegraph backends. RHI OpenGL vs Software for instance

Why rotate it around the Y axis? Would that just be a squeezing scale
transform? 45 degrees would be scaling to cos(45) of the width. Are you sure
