All Implemented Interfaces:

Pageable, Printable

Direct Known Subclasses:

IlvMapPrintableDocument

public class IlvManagerPrintableDocument
extends IlvPrintableDocument

A Document subclass for printing the content of an IlvManager. This class allows you to specify an area of the IlvManager that must be printed. This area can be printed in several pages. The pages are specified either by defining the number of rows or the number of columns. This object will automatically create the appropriate number of pages according to the area, the number of rows and columns and the page format. If both the number of rows and columns are specified, then the object will take into account only the value that results in the minimum number of pages. To print the area in one page, you may set the number of rows and the number of columns to 1.

Constructor Detail

IlvManagerPrintableDocument

public IlvManagerPrintableDocument(String name,
                                   IlvManagerView view,
                                   PageFormat pageFormat)

Creates a ManagerDocument for the specified manager view and page format.

Parameters:

view - The manager view to print.

pageFormat - The page format.

IlvManagerPrintableDocument

public IlvManagerPrintableDocument(String name,
                                   IlvManagerView view)

Creates a ManagerDocument for the specified manager view. The default page format is a letter-sized page with one-inch margins.

Parameters:

view - The manager view to print.

Method Detail

getView

public IlvManagerView getView()

Returns the manager view used when creating the document.

isPrintingAllManagerBBox

public boolean isPrintingAllManagerBBox()

Returns true if the area to be printed is the total area of the manager.

getTotalManagerPrintableArea

public IlvRect getTotalManagerPrintableArea()

Returns the total area of the manager to be printed. The value returned is in manager coordinate system.

Invisible layers and layers for which IlvManagerView.isContributingToViewBBox(int) returns false are not taken into account when calculating the area.

If the automatic zoom level calculation is enabled, the returned value may only be an approximation. In particular if the manager contains nonzoomable objects, it is recommended to disable the automatic zoom level calculation and to set the zoom transformer instead, so that the returned value is precise with respect to the given zoom transformer.

See Also:

setAutomaticZoomLevel(boolean), getZoomTransformer()

getZoomTransformer

public IlvTransformer getZoomTransformer()

Returns the zoom transformer used when printing. This zoom transformer is only used when automatic zoom level is disabled.

In the printout, the print area of the manager must be transformed to fit to the page area. However, the content of an IlvManager may change when displayed at different zoom level (for example when it contains nonzoomable objects). The zoom transformer is used to specify the zoom level when printing. Still, the print area is transformed to fit to the page area, but the zoom transformer decides for instance how much of this transformation contributes to the nonzoomable objects.

If the method returns null, the zoom transformer of the input view is used instead. In this case, the proportions between zoomable and nonzoomable objects are in the printout exactly as in the view.

JViews 8.0

setZoomTransformer

public void setZoomTransformer(IlvTransformer t)

Changes the zoom transformer used when printing. This zoom transformer is only used when automatic zoom level is disabled.

In the printout, the print area of the manager must be transformed to fit to the page area. However, the content of an IlvManager may change when displayed at different zoom level (for example when it contains nonzoomable objects). The zoom transformer is used to specify the zoom level when printing. Still, the print area is transformed to fit to the page area, but the zoom transformer decides for instance how much of this transformation contributes to the nonzoomable objects. If the input zoom transformer is null, the zoom transformer of the input view is used instead. In this case, the proportions between zoomable and nonzoomable objects are in the printout exactly as in the view.

Changing the zoom transformer may affect the result of the printing but will not affect the number of pages or the area on a page that is printed.

getZoomLevel

public double getZoomLevel()

Returns the zoom level used when printing. The zoom level is the zoom factor of the zoom transformer.

See Also:

setZoomTransformer(ilog.views.IlvTransformer)

setZoomLevel

public void setZoomLevel(double zl)

Changes the zoom level used when printing. This sets the zoom transformer to a transformation that scales in x and y direction by the same amount.

See Also:

setZoomTransformer(ilog.views.IlvTransformer), setMaximumZoomLevel(double), setMinimumZoomLevel(double), setZoomLevelModificationEnabled(boolean)

isAutomaticZoomLevel

public boolean isAutomaticZoomLevel()

Returns true if the automatic zoom level calculation is enabled. It is enabled by default.

Since:

JViews 8.0

See Also:

setAutomaticZoomLevel(boolean), setZoomTransformer(ilog.views.IlvTransformer)

setAutomaticZoomLevel

public void setAutomaticZoomLevel(boolean enable)

Sets whether the automatic zoom level calculation is enabled. It is enabled by default.

In the printout, the print area of the manager must be transformed to fit to the page area. However, the content of an IlvManager may change when displayed at different zoom level (for example when it contains nonzoomable objects). In order to adjust the printing, it is possible to set the zoom transformer (see setZoomTransformer(ilog.views.IlvTransformer)), which however has only an effect if the automatic zoom level calculation is disabled. If it is enabled, an internal zoom transformer is calculated automatically and the explicitly set zoom transformer is ignored.

isAutomaticZoomLevel(), setZoomTransformer(ilog.views.IlvTransformer)

setMaximumZoomLevel

public void setMaximumZoomLevel(double zl)
