QCamera - Setting resolution of captured preview image using QImageEncoderSettings does not work
-
I am trying to capture images via QCamera API using Qt 4.7.3 & QtMoblity 1.1.1 on Symbian^3 devices - Nokia N8 & E7.
The default resolution of the captured image (available via signal QCameraImageCapture::imageCaptured(int , const QImage &)) is 640x480.I want to capture the images at much higher resolutions (of-course the ones supported by the device camera).
I tried changing the setting using e.g.:viewFinder = new QGraphicsVideoItem();
viewFinder->setSize(QSizeF(640, 360));camera->setViewfinder(m_viewFinder);
imageCapture = new QCameraImageCapture(camera);QImageEncoderSettings imageSettings;
imageSettings.setCodec("image/jpeg");
imageSettings.setResolution(1600, 1200);imageCapture->setImageSettings(imageSettings);
However the resulting resolution of the captured image remains unchanged - 640x480.
Even I tried changing the setting after the camera is in active state, but no luck.By any chance the Symbian camera back-end dose not support these settings as yet ?
Any other way to change the resolution of the captured image (except scaling the captured image) ?Any help is much appreciated.
Thanks.
