Okay so I figured it out.
I'll post the code in case anyone else needs it, and remember this is a
ColdFusion implementation :
public function resetLinks( string source, string destination) {
try {
// initialize objects
Local.reader = createObject("java",
"com.lowagie.text.pdf.PdfReader").init( arguments.source );
Local.pdfName = createObject("java",
"com.lowagie.text.pdf.PdfName");
Local.annot = createObject("java",
"com.lowagie.text.pdf.PdfAnnotation");
Local.out = createObject("java", "java.io.FileOutputStream").init(
arguments.destination );
Local.stamper = createObject("java",
"com.lowagie.text.pdf.PdfStamper").init(Local.reader, Local.out);
Local.PdfAction = createObject("java",
"com.lowagie.text.pdf.PdfAction");
Local.PdfRect = createObject("java", "com.lowagie.text.Rectangle");
Local.PdfBorderArray = createObject("java",
"com.lowagie.text.pdf.PdfBorderArray").init(javacast("float", "0"),
javacast("float", "0"), javacast("float", "0"));
Local.newAnnots = [];
// check each page for hyperlinks
// Save the data to a structure then write it to an array
// then delete the hyperlink Annotation
for ( Local.i = 1; Local.i <= Local.reader.getNumberOfPages();
Local.i = Local.i + 1) {
//Get all of the annotations for the current page
Local.page = Local.reader.getPageN( Local.i );
Local.annotations = Local.page.getAsArray( Local.PdfName.ANNOTS
).getArrayList();
// search annotations for links
for (Local.x = arrayLen(Local.annotations); !isNull(
Local.annotations) && Local.x > 0; Local.x--) {
// get current properties
Local.current = Local.annotations[ Local.x ];
Local.dictionary = Local.reader.getPdfObject( Local.current
);
Local.subType = Local.dictionary.get(
Local.PdfName.SUBTYPE );
Local.action = Local.dictionary.get( Local.PdfName.A );
Local.hasLink = true;
//Skip this item if it does not have a link AND action
if (Local.subType != Local.PdfName.LINK ||
isNull(Local.action)) {
Local.hasLink = false;
}
//Skip this item if it does not have a URI
if ( Local.hasLink && Local.action.get( Local.PdfName.S ) !=
Local.PdfName.URI ) {
Local.hasLink = false;
}
//If it is a valid URI, update link
if (Local.hasLink) {
// extract file name from URL
Local.oldLink = Local.action.get( Local.pdfName.URI );
Local.newLink = getFileFromPath( Local.oldLink );
Local.Rect = Local.dictionary.Get(PdfName.Rect);
arrayStruct = StructNew();
arrayStruct.rectSTR = Local.Rect.toString();
arrayStruct.link = Local.newLink;
arrayStruct.page = Local.i;
ArrayAppend(Local.newAnnots, arrayStruct);
// Delete
Local.annotations.remove(Local.current);
}
}
}
// Now really remove them!
Local.reader.RemoveUnusedObjects();
// Now loop over the saved annotations and put them back!!
for ( Local.z = 1; Local.z <= ArrayLen(Local.newAnnots); Local.z++)
{
// Parse the rect we got save into an Array
theRectArray =
ListToArray(ReplaceNoCase(ReplaceNoCase(Local.newAnnots[z].rectSTR, "[",
""), "]", ""));
// Create the GoToR action
theAction = Local.PdfAction.gotoRemotePage(javacast("string",
'#Local.newAnnots[z].link#'), javacast("string",
'#Local.newAnnots[z].link#'), javacast("boolean", "false"),
javacast("boolean", "false"));
// Create the Link Annotation with the above Action and the Rect
theAnnot = Local.annot.createLink(Local.stamper.getWriter(),
Local.PdfRect.init(javacast("int", theRectArray[1]), javacast("int",
theRectArray[2]), javacast("int", theRectArray[3]), javacast("int",
theRectArray[4])), Local.annot.HIGHLIGHT_INVERT, theAction);
// Remove the border the underlying underlined text will flag
item as a link
theAnnot.setBorder(Local.PdfBorderArray);
// Add the Annotation to the Page
Local.stamper.addAnnotation(theAnnot, Local.newAnnots[z].page);
}
}
finally {
// cleanup
if (structKeyExists(Local, "reader")) { Local.reader.close(); }
if (structKeyExists(Local, "stamper")) { Local.stamper.close(); }
if (structKeyExists(Local, "out")) { Local.out.close(); }
}
}
