Detailed Description
QCameraFormat represents a certain video format supported by a camera device.
The format is a combination of a pixel format, resolution and a range of frame rates.
QCameraFormat objects can be queried from QCameraDevice to inspect the set of supported video formats.
See also QCameraDevice and QCamera.
Member Function Documentation
QCameraFormat::QCameraFormat(const QCameraFormat &other)
Copy constructs a camera format from the other format.
QCameraFormat::QCameraFormat()
Constructs a null camera format.
See also isNull().
QCameraFormat &QCameraFormat::operator=(const QCameraFormat &other)
Assign other to this.
QCameraFormat::~QCameraFormat()
Destructs the camera format object.
bool QCameraFormat::isNull() const
Returns true if this is a default constructed QCameraFormat.
float QCameraFormat::maxFrameRate() const
Returns the highest frame rate defined by this format.
In 6.2, the camera will always try to use the highest frame rate supported by a certain video format.
Note: Getter function for property maxFrameRate.
float QCameraFormat::minFrameRate() const
Returns the lowest frame rate defined by this format.
Note: Getter function for property minFrameRate.
QVideoFrameFormat::PixelFormat QCameraFormat::pixelFormat() const
Returns the pixel format.
Most commonly this is either QVideoFrameFormat::Format_Jpeg or QVideoFrameFormat::Format_YUVY but other formats could also be supported by the camera.
Note: Getter function for property pixelFormat.
See also QVideoFrameFormat::PixelFormat.
QSize QCameraFormat::resolution() const
Returns the resolution.
Note: Getter function for property resolution.
bool QCameraFormat::operator!=(const QCameraFormat &other) const
Returns false
if the other format is equal to this camera format, otherwise true
.
bool QCameraFormat::operator==(const QCameraFormat &other) const
Returns true
if the other format is equal to this camera format, otherwise false
.
