Create multi-page ISO reports (C#)

For reports printed on ISO and JIS-sized pages, you can configure the output to print several logical pages per physical page.


This code snippet uses properties and methods from the MultiPageMapper class:
// start code snippet

String designFile = "OrderReport.4rp";
String outputFilename = "PDFoutput.pdf";

FormatHandler handler = new FormatWriter(outputFilename);
PDFRenderer renderer = new PDFRenderer(handler);

//Defining the Multipage
PXMLConsumer multiPageLayout = new PXMLLayouter(renderer);
MultiPageMapper myMultiPageMapper = new MultiPageMapper(multiPageLayout);
myMultiPageMapper.isoNumber = 4;
myMultiPageMapper.pageExponent = 2;
myMultiPageMapper.portrait = true;
myMultiPageMapper.paperLeftMargin = "2mm";
myMultiPageMapper.paperRightMargin = "2mm";
myMultiPageMapper.paperTopMargin = "2mm";
myMultiPageMapper.paperBottomMargin = "2mm";
multiPageLayout = myMultiPageMapper;

FourRpProcessor report = new FourRpProcessor(designFile, multiPageLayout);

//Run the report 

// some code omitted - view full source in demo

// open the file:

// stop code snippet
The MultiPageMapper class is used to specify how many logical pages are placed on a physical page, as well as page sizing issues.
Note: For MultiPageMapper, you must use the FourRpProcessor; you cannot use the shortcut.
  • The isoNumber property specifies the ISO value of the physical page. In our example, 4 specifies an A4 ISO page size.
  • The pageExponent property specifies the number of logical pages to place on the physical page, as an index of 2. In our example, myMultiPageMapper.pageExponent = 2 specifies that 2*2 report pages, or 4 logical pages, will print on each physical page. If myMultiPageMapper.pageExponent = 3 is specified, then 2*2*2 report pages, or 8 logical pages, will be printed on each physical page.
  • The portrait property sets the orientation of the logical pages of the report. When set to true, the logical pages are portrait.
  • The paperLeftMargin, paperRightMargin, paperTopMargin and paperBottomMargin properties set the margins for the physical page. In this example, the margins are set for 2mm on all sides.

Once the MultiPageMapper object is defined, it is used to set the value for the PXMLConsumer object, which then becomes the input for the FourRpProcessor.
