How to render multiple Notes Documents to single PDF output?

#26206

Hi,

Is there sample code to render multiple Notes documents (selected from a Notes view) to a single output pdf? Each Notes Document should be separated by a page break within the output pdf file.

Any examples or pointers are greatly appreciated.

Thanks

I would implement the multi-doc converter this way (replace the correspondingreference agent https://pd4ml.com/i/PdfAgentR7.java methods with the following):

public void NotesMain() {
try {
Session session = getSession();
AgentContext agentContext = session.getAgentContext();

System.out.println("AGENT start.");

Database db = agentContext.getCurrentDatabase();

String xsl = null;

if (readXslFromJar) {
xsl = getXsl();
} else {
DocumentCollection dcx =
db.search("@Contains(Form; "" + xslDocumentFormName + "")");
Document xsldoc = dcx.getFirstDocument();
if (xsldoc != null) {
xsl = xsldoc.getItemValueString(xslDocumentFieldName);
} else {
throw new IOException( "Can not find " + xslName);
}
}

// System.out.println("XSL: " + xsl);

// collect selected documents
DocumentCollection dc = agentContext.getUnprocessedDocuments();

URL[] urls = new URL[dc.getCount()];
int ind = 0;

Document doc = dc.getFirstDocument();
while (doc != null) {

Document tmp = db.createDocument();
RichTextItem rti = tmp.createRichTextItem("PD4MLBody");
doc.renderToRTItem(rti);

DxlExporter dxl = session.createDxlExporter();
dxl.setConvertNotesBitmapsToGIF(true);
dxl.setOutputDOCTYPE(false);
String xml = dxl.exportDxl(tmp);

String xml = getTestDxl();

System.out.println("DXL FORM: " + xml);

System.out.println("TRANS: " + System.getProperty("java.version"));
System.out.println("TRANS: " + System.getProperty("java.vm.version"));
System.out.println("TRANS: " + System.getProperty("java.vm.vendor"));
System.out.println("TRANS: " + System.getProperty("java.vm.name"));

long start = System.currentTimeMillis();

String html = transformXML(xml, xsl);


long middle = System.currentTimeMillis();
System.out.println("XSL transformation: " + (middle-start) + "ms");

System.out.println("HTML: " + html);

File htmlFile = File.createTempFile("pd4dxl", ".html");
java.io.FileOutputStream fos = new java.io.FileOutputStream( htmlFile );
fos.write( html.getBytes() );

urls[ind++] = htmlFile.toURL();

doc = dc.getNextDocument();
}

File pdf = File.createTempFile("pd4ml", ".pdf");
java.io.FileOutputStream fos = new java.io.FileOutputStream(pdf);
generatePDF( urls,
fos,
PD4Constants.A4,
"java:/fonts",
"<font color="green" face="tahoma">DXL to PDF convesion result." +
" $[page] of $[total]</font>");

System.out.println("PDF file " + pdf.toURL() + " is generated" );

System.out.println("AGENT done.");

} catch (SAXException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}

public static final void generatePDF(URL[] urls, OutputStream fos,
Dimension format, String fontsDir, String footerBody)
throws Exception {

PD4ML pd4ml = new PD4ML();
pd4ml.setPageInsets(new Insets(20, 10, 10, 10));
pd4ml.setHtmlWidth(1000);
pd4ml.setPageSize(format);

if (fontsDir != null && fontsDir.length() > 0) {
pd4ml.useTTF(fontsDir, true);
}

if (footerBody != null && footerBody.length() > 0) {
PD4PageMark footer = new PD4PageMark();
footer.setAreaHeight(-1);
footer.setHtmlTemplate(footerBody);
pd4ml.setPageFooter(footer);
}

pd4ml.render( urls, fos);
fos.flush();
fos.close();
}

The code is schematic and needs to be optimized.

After the resulting PDF is stored/sent/etc, the TEMP directory needs to be cleaned up. So it makes sence to register object references, created by the calls

File htmlFile = File.createTempFile("pd4dxl", ".html");
File pdf = File.createTempFile("pd4ml", ".pdf"); 

and to remove them later, close to the agent code end.
