snapToRect()

QRect PhosphorCompositor::GeometryHelpers::snapToRect ( const QRectF &  rf )

inline

Convert QRectF to QRect with edge-consistent rounding.

Unlike QRectF::toRect() which rounds x, y, width, height independently, this rounds the edges (left, top, right, bottom) and derives width/height from the rounded edges. This ensures adjacent zones sharing an edge always produce exactly the configured gap between them, even when fractional scaling (e.g. 1.2x) produces non-integer zone boundaries.
