返回类型

int

Initiates the capture of an image to fileName 。 fileName can be relative or empty, in this case the service should use the system specific place and file naming scheme.

The Camera service should save all the capture parameters like exposure settings or image processing parameters, so changes to camera parameters after is called do not affect previous capture requests.

Returns the capture request id number, which is used later with imageExposed() , imageCaptured() and imageSaved() signals.

• id – int

• error – int

• errorString – unicode

PySide2.QtMultimedia.QCameraImageCaptureControl. imageAvailable ( requestId , buffer ) ¶

参数

• requestId – int

• buffer – QVideoFrame

PySide2.QtMultimedia.QCameraImageCaptureControl. imageCaptured ( requestId , preview ) ¶

参数

• requestId – int

• preview – QImage

PySide2.QtMultimedia.QCameraImageCaptureControl. imageExposed ( requestId ) ¶

PySide2.QtMultimedia.QCameraImageCaptureControl. isReadyForCapture ( ) ¶

返回类型

bool

Identifies if a capture control is ready to perform a capture immediately (all the resources necessary for image capture are allocated, hardware initialized, flash is charged, etc).

Returns true if the camera is ready for capture; and false if it is not.

It’s permissible to call capture() while the camera status is ActiveStatus regardless of property value. If camera is not ready to capture image immediately, the capture request is queued with all the related camera settings to be executed as soon as possible.

参数

ready – bool

PySide2.QtMultimedia.QCameraImageCaptureControl. setDriveMode ( mode ) ¶
