Bug ID: 431466
Summary: GeoPainter::regionFromRect() uses centerPosition
argument as top-left point instead
Product: marble
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: marble-b...@kde.org
Reporter: johan...@zarl-zierl.at
Target Milestone: ---
SUMMARY
GeoPainter::regionFromRect() is advertised as parameter-compatible with
GeoPainter::drawRect(). However, the resulting region is not centered around
the centerPoint, but rather uses it as top-left corner for the resulting
QRegion.
STEPS TO REPRODUCE
1. Use drawRect to render a non-geoprojected rectangle
2. Use regionFromRect with the same parameters to create a QRegion
3. Draw the resulting region using drawRect in screen coordinates
OBSERVED RESULT
The rectangle rendered in step 3 is centered around the bottom-right corner of
the rectangle rendered in step 1.
EXPECTED RESULT
Both rectangles should overlap around the same center.
