A filter for cropping images.
Supports options: CropRectangle (the crop rectangle, in full-image coordinates)
Default behavior: does nothing.

QuillImage Crop::apply | ( | const QuillImage & | image | ) | const [virtual] |
Applies the filter to a given preview or fragment.
Reimplemented from QuillImageFilterImplementation.
virtual const QString Crop::name | ( | ) | const [inline, virtual] |
Reimplemented from QuillImageFilterImplementation.
QRect Crop::newArea | ( | const QSize & | fullImageSize, | |
const QRect & | area | |||
) | const [virtual] |
If the filter changes dimensions of the image, this can be used to re-calculate a new position for a specific tile.
Reimplemented from QuillImageFilterImplementation.
QSize Crop::newFullImageSize | ( | const QSize & | fullImageSize | ) | const [virtual] |
If the filter changes dimensions of the image, this can be used to re-calculate a new size for the full image.
Reimplemented from QuillImageFilterImplementation.
QVariant Crop::option | ( | const QString & | filterOption | ) | const [virtual] |
Returns the value of a filter option. These options are the recommended way to pass information to the filters. This function needs to be reimplemented in a derived class to support options.
Reimplemented from QuillImageFilterImplementation.
bool Crop::setOption | ( | const QString & | filterOption, | |
const QVariant & | value | |||
) | [virtual] |
Sets the value of a filter option. These options are the recommended way to pass information to the filters. This function needs to be reimplemented in a derived class to support options.
Reimplemented from QuillImageFilterImplementation.
const QStringList Crop::supportedOptions | ( | ) | const [virtual] |
