--- Comment #4 from Jean-Baptiste Mardelle <j...@kdenlive.org> ---
Git commit 3f8105070aeedcf09adba716f79639fc63f72f96 by Jean-Baptiste Mardelle,
on behalf of Eric Jiang.

Change vectorscope to use QImage::pixel()
Vectorscope tried to directly reinterpret the input QImage as RGB
data, which makes an assumption that the input is RGB. On Windows, the
input QImage is BGR, causing red and blue to be switched in the
Vectorscope.
QImage::pixel() checks QImageData->format and converts the to QRgb
appropriately. Casual benchmarking seems to show that using pixel() is
about 5% slower for each vectorscope calculation in the no-conversion
case (e.g. Linux).
