Unsolved Access original imagedata captured by Android QML camera
-
Hey,
I am using a QML Camera object for capturing a image and a C++ class for processing the captured image. Until now the code looks like this:
QML Camera object :
Camera { id: camera captureMode: Camera.CaptureStillImage imageCapture { onImageCaptured: { imagecaptured.source = preview; imgProcessor.processImage(preview); } } }
process Image in C++:
void ImgProcessor::processImage(const QString& path) { QUrl imageURL(path); QQmlEngine* engine = QQmlEngine::contextForObject(this)->engine(); QQmlImageProviderBase* imageProviderBase = engine->imageProvider(imageURL.host()); QQuickImageProvider* imageProvider = static_cast<QQuickImageProvider*> (imageProviderBase); QSize imageSize; QString imageId = imageURL.path().remove(0,1); QImage image = imageProvider->requestImage(imageId, &imageSize, imageSize); }
What I get from QML camera is a preview which has a very small image size. (in my case 704 x 528)
Is there a possibility to get the original image size ( 4608 x 3456 ) or to access the raw image data?dev environment:
OS: windows 7
dev for android version 4.4.2
qt creator 3.5
qt quick 2.5
qt 5.5 -
onImageSaved gives you the path to the actual image.

thanks for your response.
is it also possible to access the image data before the saving process?
