Create a PDF portfolio (package) in Android

To create a PDF portfolio containing multiple file types.

Java

void addPackage(PDFDoc doc, String file, String desc) throws PDFNetException {
	NameTree files = NameTree.create(doc.getSDFDoc(), "EmbeddedFiles");
	FileSpec fs = FileSpec.create(doc, file, true);
	files.put(file.getBytes(), fs.getSDFObj());
	fs.getSDFObj().putText("Desc", desc);

	Obj collection = doc.getRoot().findObj("Collection");
	if (collection == null) collection = doc.getRoot().putDict("Collection");

	// You could here manipulate any entry in the Collection dictionary.
	// For example, the following line sets the tile mode for initial view mode
	// Please refer to section '2.3.5 Collections' in PDF Reference for details.
	collection.putName("View", "T");
}
PDFDoc doc = new PDFDoc();
AddPackage(doc, filename, "PDF");
AddPackage(doc, imagename, "Image");

Kotlin

@Throws(PDFNetException::class)
fun addPackage(doc: PDFDoc, file: String, desc: String) {
	val files = NameTree.create(doc.sdfDoc, "EmbeddedFiles")
	val fs = FileSpec.create(doc, file, true)
	files.put(file.toByteArray(), fs.sdfObj)
	fs.sdfObj.putText("Desc", desc)

	var collection: Obj? = doc.root.findObj("Collection")
	if (collection == null) collection = doc.root.putDict("Collection")

	// You could here manipulate any entry in the Collection dictionary.
	// For example, the following line sets the tile mode for initial view mode
	// Please refer to section '2.3.5 Collections' in PDF Reference for details.
	collection!!.putName("View", "T")
}
val doc = PDFDoc()
AddPackage(doc, filename, "PDF")
AddPackage(doc, imagename, "Image")
