how can i rotate the screen

[rihani]

Hi,

how could i rotate the screen please thanks

[Wolftronics-SBC]

you can rotate the camera or monitor? monitor rotate linux,windows.... camera rotate videoGrabber->setRotation(ROTATION_90); videoGrabber->setRotation(272); etc...

I think example-direct-mode-transform has this as a demo - take a look at that

https://github.com/jvcleave/ofxRPiCameraVideoGrabber/blob/master/example-direct-mode-transform/src/ofApp.cpp#L118

I don't have the camera hooked up at the moment to try it

I get the following error

error: base operand of ‘->’ has non-pointer type ‘ofxRPiCameraVideoGrabber’
         videoGrabber->setRotation(ROTATION_90);

I do insert this in keyPressed function but don't mind setting this during setup()

void ofApp::keyPressed  (int key)
{
    ofLog(OF_LOG_VERBOSE, "%c keyPressed", key);

    if (key == 'e')
    {
        videoGrabber.setImageFilter(filterCollection.getNextFilter());
    }

    if(key == 'm')  
    {
        videoGrabber->setRotation(ROTATION_90);
    }
....

the error says it's not a pointer in your code, change videoGrabber->setRotation(ROTATION_90); to videoGrabber.setRotation(ROTATION_90);

managed to do it using

videoGrabber.setDisplayRotation(rotation);

thanks

i managed to spin the camera 180 degrees using videoGrabber.setRotation(ROTATION_180); however how can i flip/mirror the camera vertically

[rihani]

videoGrabber.setMirror(MIRROR_VERTICAL);
