Image view item for QML.
This class (or an extended subclass) should be registered in QML. The item provides an image display. Instances should only be created from QML.
For convenience see ImageViewItem.register
See examples for available properties.
| None register | ( | cls, | |
| str | uri = "CvbQuick", |

| int | version_major = 1, |

| ) |
Convenience method to register this type or a derived type in QML.
Basically just calls qmlRegisterType(...).
uri : str URI forwarded to Qt.
version_major : int Major version forwarded to Qt.
version_minor : int Minor version forwarded to Qt.
qml_name : str Name in QML forwarded to Qt.
| bool try_translate | ( | self, | |
| PySide2.QtCore.QPointF | translation | ||
| ) |
This method can be called from QML!
translation : QPointF Point interpreted as vector to translate.
bool True if successful, false otherwise.
| bool try_zoom_in | ( | self | ) |
Tries to zoom in.
This method can be called from QML!
bool True if successful, false otherwise.
| bool try_zoom_out | ( | self | ) |
Tries to zoom out.
This method can be called from QML!
bool True if successful, false otherwise.
