Revision history [back]

this is a "shallow" copy (it will copy the Mat header & the data pointer, but NOT the pixels):

  mRgba = inputFrame.rgba();

same here:

  Mat mRgba2 = inputFrame.rgba();

so, both Mats point to the same data now !

if you draw something into mRgba2, it will show up in mRgba, too.

to avoid it, you need a "deep" copy:

  Mat mRgba2 = inputFrame.rgba().clone();
