QImageEncoderSettings ¶

概要 ¶

详细描述 ¶

A image encoder settings object is used to specify the image encoder settings used by QCameraImageCapture . Image encoder settings are selected by constructing a QImageEncoderSettings object, setting the desired properties and then passing it to a QCameraImageCapture instance using the QCameraImageCapture::setImageSettings() function.

QImageEncoderSettings imageSettings;
imageSettings.setCodec("image/jpeg");
imageSettings.setResolution(1600, 1200);
imageCapture->setEncodingSettings(imageSettings);
