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();
imageCapture = new QCameraImageCapture(camera);
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.
The signal imageCapture() send just a preview image - which obviously is low res. The real photo is send with imageSaved() -- either a disk file or a buffer (if the N8 implementation supports that).
