52 \brief The QImageEncoderControl class provides access to the settings of a media service that |
|
53 performs image encoding. |
|
54 |
|
55 If a QMediaService supports encoding image data it will implement QImageEncoderControl. |
|
56 This control allows to \l {setImageSettings()}{set image encoding settings} and |
|
57 provides functions for quering supported image \l {supportedImageCodecs()}{codecs} and |
|
58 \l {supportedResolutions()}{resolutions}. |
|
59 |
|
60 The interface name of QImageEncoderControl is \c com.nokia.Qt.QImageEncoderControl/1.0 as |
|
61 defined in QImageEncoderControl_iid. |
