Detailed Description

to print what is displayed on a a2dCanvasView or the whole document as seen from the showobject of the drawer.

Internal a second wxDarwer class is initiated with a mapping that nicely fits that mapping of the input a2dCanvasView to a piece of paper. This mapping depends on the type of print. If only what is on the view needs to be printed, the mapping of the input drawer is used, but if the whole document is wanted as seen from the ShowObject() of the input drawer, the boundingbox of the showobject will be used for the mapping.

Constructor & Destructor Documentation

a2dViewPrintout::a2dViewPrintout	(	a2dCanvasView *	drawer,
		const wxString &	title,
		const wxString &	filename,
		a2dCommand *	typeOfPrint,
		bool	drawframe,
		double	scalelimit,
		bool	fitToPage
	)

initialize mapping based on an existing canvas

Parameters:

	drawer	the a2dCanvasView from which the print is wanted.
	title	title at top of the print
	filename	the name of the file to be printed (may be empty )
	typeOfPrint	When called from a2dDocumentCommandProcessor, the a2dCommand* which lead to this call.

Depending on the command one can organize printing features. Like in the default implementation:

                a2dCommand_Print::a2dPrintWhat
                {
                    Print,     
                    Preview,    
                    PrintView,     
                    PreviewView,     
                    PrintDocument,     
                    PreviewDocument,  
                    PrintSetup
                };

Here View is to only print what is the visible view. Document print the document as seen from the a2dView::ShowObject(), it fits this to the paper.

Parameters:

	drawframe	print a frame rectangle in bounding box of drawing/view
	scalelimit	limits the scaling (world/pixel) to the given value, so that small graphics are not zoomed to full page
	fitToPage	scale to fit the page

Member Function Documentation

bool a2dViewPrintout::OnPrintPage

(

int

)

called for every page to print, for a2dCanvasDocument in general just one.

It redraws/rerenders without double buffering the view or document on the pinter its wxDC. Internal a a2dDcDrawer is used to redraw the a2dCanvasDocument on the device.

needed ?

now draw to the area within the margins

Reimplemented from a2dDocumentPrintout.

Member Data Documentation

bool a2dViewPrintout::m_fitToPage [protected]

draw a view without real scale, the scaling in X and Y may differ. The drawing is adjusted in X and Y seperately to draw until the sides/border of the printer area
