OF 7.1 how to use ofxCvGrayscaleImage in the mirror()

In OpencvExample examples,
void testApp::update(){

grayImage = colorImg;
grayImage.mirror(false,true); // my add

}

Program runs, it might crash…
In the same test in of7.0 no problem…

runs fine for me on Mac 10.6.8 - what platform are you on?

:frowning: I’m using win7 + codeblock 10.05 + of 0.71…

do you mind opening an issue on github?

Is that right?
I did not submit issues to git the experience…

awesome - yeah - that will get the attention of someone who can test it on windows
