Constructor Detail

CommonToolHandler

public CommonToolHandler(DocumentViewController documentViewController,
                         AbstractPageViewComponent pageViewComponent,
                         DocumentViewModel documentViewModel)

Create a new common tool handler. The tool handle can operate on a view or at the page level. If the handler only operates at the view level then pageViewComponent can be set to null;

Parameters:

documentViewController - parent view controller

pageViewComponent - page view component tool acts on, can be null for view tool handlers.

documentViewModel - parent document model

Method Detail

getPageTransform

protected java.awt.geom.AffineTransform getPageTransform()

getPageTransform

protected java.awt.geom.AffineTransform getPageTransform(AbstractPageViewComponent pageViewComponent)

convertToPageSpace

protected java.awt.Shape convertToPageSpace(java.awt.Shape shape)

Convert the shapes that make up the annotation to page space so that they will scale correctly at different zooms.

Returns:

transformed bBox.

convertToPageSpace

protected java.awt.Shape convertToPageSpace(AbstractPageViewComponent pageViewComponent,
                                            java.awt.Shape shape)

convertToPageSpace

protected java.awt.geom.Point2D[] convertToPageSpace(java.awt.geom.Point2D start,
                                                     java.awt.geom.Point2D end)

convertMouseToPageSpace

protected java.awt.geom.Point2D.Float convertMouseToPageSpace(java.awt.Point mousePoint,
                                                              java.awt.geom.AffineTransform pageTransform)

Convert the mouse coordinates to the space specified by the pageTransform matrix. This is a utility method for converting the mouse coordinates to page space so that it can be used in a contains calculation for text selection.

Parameters:

mousePoint - point to convert space of

pageTransform - transform

Returns:

page space mouse coordinates.

convertRectangleToPageSpace

protected java.awt.geom.Rectangle2D convertRectangleToPageSpace(java.awt.Rectangle mouseRect,
                                                                java.awt.geom.AffineTransform pageTransform)

Converts the rectangle to the space specified by the page transform. This is a utility method for converting a selection rectangle to page space so that an intersection can be calculated to determine a selected state.

Parameters:

mouseRect - rectangle to convert space of

pageTransform - page transform

Returns:

converted rectangle.
