mergePDF

This command is deprecated, use combinePDF command instead.

Combines two specified PDF files into one and stores the resulting PDF file into the variable context. The two PDFs may be from external sources or be products of other commands, such as exportPDF or this command itself.

This command is not available in Task and Batch APIs.

secondDoc
Required	Value type	EL-evaluated
Yes	File	Yes
Defines the other PDF file of the merging process. In the merged result, this file's content will follow the content of `firstDoc`.

Examples

A basic example is to add an appendix to the PDF created out of your composed document. The appendix could be a resource found in your Salesforce organization, which the logic can download and then merge into your result document.

CODE

<exportPDF document="${composedDoc}" var="resultPDF"><load recordID="${appendixPDFrecord}" var="appendixPDF"><mergePDF firstDoc="${resultPDF}" secondDoc="${appendixPDF}" var="completePDF">

As the result of the merging is also a PDF file, it is possible to keep merging more documents into it. If you had more than one PDF you wish to merge into your result document, it is a good idea to store the mergedPDF into the same variable as the result document to keep the logic simpler. Like this:

CODE

<exportPDF document="${composedDoc}" var="resultPDF"><mergePDF firstDoc="${resultPDF}" secondDoc="${appendixPDF}" var="resultPDF"><mergePDF firstDoc="${resultPDF}" secondDoc="${anotherPDF}" var="resultPDF"><mergePDF firstDoc="${resultPDF}" secondDoc="${yetAnotherPDF}" var="resultPDF">

Should you have a variable amount of PDFs in a Collection to be merged, they can be merged easily with mergePDFCollection, or manually by looping through them with forEach. A specific thing to note with the loop is that due to forEach creating its own local variable context, the merged PDF's variable needs to be created somewhere outside of the loop and the set command has to be used to store the merged result into this variable in the main context.

CODE

<exportPDF document="${composedDoc}" var="resultPDF"><forEach value="${pdfAppendices}" var="appendixPDF"><mergePDF firstDoc="${resultPDF}" secondDoc="${appendixPDF}" var="mergedPDF"><set var="resultPDF" value="${mergedPDF}">
