53 | \brief The QImageEncoderControl class provides access to the settings of a media service that |
54 | performs image encoding. |
55 | |
56 | If a QMediaService supports encoding image data it will implement QImageEncoderControl. |
57 | This control allows to \l {setImageSettings()}{set image encoding settings} and |
58 | provides functions for quering supported image \l {supportedImageCodecs()}{codecs} and |
59 | \l {supportedResolutions()}{resolutions}. |
60 | |
61 | The interface name of QImageEncoderControl is \c org.qt-project.qt.imageencodercontrol/5.0 as |
62 | defined in QImageEncoderControl_iid. |
