Member Function Documentation

QDialog * QGLPreviewOperation::getUI ( QWidget *  parent = 0)

virtual

Obtain QWidget with user interface for the operation.

The returned widget will be reparented. That means it will be automatically freed by Qt when closed. Trying to free the the returned QWidget memory manually in the FotoSHOCKOperation desctructor will most likely cause crashes.

Parameters

parent

the parent for the dialog. If the parent is not set in this function the UI may not be shown correctly. The parent must be set in the dialog constructor, otherwise the dialog will not be shown when calling the show() function (Qt bug?). This is important especially for the preview.

Returns

UI for the operation

Implements IFotoSHOCKOperation.

void QGLPreviewOperation::runOperation ( const FotoSHOCKcore::Inputs &  sources, const FotoSHOCKcore::Outputs &  dest, vector< FotoSHOCKcore::UpdateInfo > &  ROI, const long  stamp  )

virtual

Apply the operation.

Apply the operation on the given input ImageBuffers and output it in a destination buffer.

The source buffers and destination buffer can be considered as having the same PixelFormat except for some internal GraphManager operations.

Parameters

sources	source buffers
dest	destination buffers
ROI	list of regions where the operation should be recalculated. The specified ROI is not a hard limit, the region recalculated can be bigger than ROI.
stamp	identifier which the operation should use to identify itself. That means you should set the tile stamp to this value in the implementation. The stamp can used to check whether the requested region of a buffer has been already processed by the operation to reduce the amount of processed data

Implements FotoSHOCKcore::ImageOperation.
