Create multi-page ISO reports (Swift)

The Swift report application tells the report engine to render several report pages onto a physical page. This is completed with these C APIs:

selectLogicalPageMapping()

Configures the mapping from logical pages to physical pages. For the purpose of creating a multi-page ISO report, this will be set to multipage.

configureMultipageOutput()

Defines the configuration of the logical pages on the physical page, the size of the ISO page, and the orientation of the logical page.

This example modifies the OrderReportSwift.swift file, which you can find in the OrderReportSwift demo project, to output multiple report pages onto a physical page.

let rcPtr = createRuntimeConfiguration(designFile)
setOutputFileName(rcPtr, outputFilename)
selectDevice (rcPtr, PDF)
selectLogicalPageMapping(rcPtr,multipage)
configureMultipageOutput(rcPtr,2,4,TRUE)
configureDistributedProcessing(rcPtr, "127.0.0.1", 7000)

Specifically:

• The selectLogicalPageMapping function tells the output that there will be several logical pages on a physical page.
• The configureMultipageOutput function details the configuration of the logical pages on the physical page, the size of the ISO page, and the orientation of the logical page. In our example:
  • The second parameter specfies the number of logical pages to print, but is provided as an index of two. In our example, 2 * 2 = 4 logical pages will print on each physical page. If it had been set to three, then 2 * 2 * 2 = 8 logical pages would have been printed on each physical page.
  • The third parameter specifies the ISO number. In our example, 4 refers to ISOA4.
  • The fourth and final parameter specifies whether the logical page orientation should be portrait (TRUE) or landscape (FALSE).
