AddWatermark.java – This program will add a semi-transparent watermark to a document.

PDFToTIFF.java – This program converts a PDF file to a multi-page TIFF file.

keytool -genkey -keystore test.pfx -storetype pkcs12 -storepass store_pwd -keypass key_pwd -alias key_alias

ExtractText.java – Extract text content from a document.

AddBookmarks.java – Adds a bookmark for every page in a document.

AddTOC.java – Creates a table of contents at the head of the document. This sample adds a page at the top of the document and then adds a page title and a link to every page in the document.

AddTextHighlight.java – Searches for occurrences of a text string and adds highlight annotations for the text if found.
