Outlines JavaScript action

Hi Paulo,

It is a simple fix that works just for my example: I do not have the entire knowledge about the PDF format to do more.

The fixes are the following ones:

- For the method boormakDepth (SimpleBoookmark class): Add the management of the _javascript_ Action

{…}

else if (PdfName.LAUNCH.equals(PdfReader.getPdfObject(myAction.get(PdfName.S)))) {

myMap.put("Action", "Launch");

PdfObject file = PdfReader.getPdfObject(myAction.get(PdfName.F));

if (file == null)

file = PdfReader.getPdfObject(myAction.get(PdfName.WIN));

if (file != null) {

if (file.isString()) {

myMap.put("File", ((PdfString)file).toUnicodeString());

} else if (file.isDictionary()) {

file = PdfReader.getPdfObject(((PdfDictionary)file).get(PdfName.F));

if (file.isString()) {

myMap.put("File", ((PdfString)file).toUnicodeString());

}

else if (PdfName._javascript_.equals(PdfReader.getPdfObject(myAction.get(PdfName.S)))) {

PdfObject myJS = PdfReader.getPdfObject(myAction.get(PdfName.JS));

if (myJS != null) {

if (myJS.isString()) {

String myPage = myJS.toString().substring(myJS.toString().lastIndexOf('=')+1, myJS.toString().lastIndexOf(';')).trim();

myMap.put("Page", String.valueOf(Integer.parseInt(myPage)+1));

}

myMap.put("Action", "_javascript_");

}

{…}

- For the method createOutlineAction

{…}

else if ("Launch".equals(action)) {

String file = (String)map.get("File");

if (file != null) {

PdfDictionary dic = new PdfDictionary();

dic.put(PdfName.S, PdfName.LAUNCH);

dic.put(PdfName.F, new PdfString(file));

outline.put(PdfName.A, dic);

}

// --- 2006-10-30: Add the management of the _javascript_ Action

else if ("_javascript_".equals(action)) {

String p;

if ((p = (String)map.get("Named")) != null) {

if (namedAsNames)

outline.put(PdfName.DEST, new PdfName(p));

else

outline.put(PdfName.DEST, new PdfString(p, null));

}

else if ((p = (String)map.get("Page")) != null) {

PdfArray ar = new PdfArray();

StringTokenizer tk = new StringTokenizer(p);

int n = Integer.parseInt(tk.nextToken());

ar.add(writer.getPageReference(n));

if (!tk.hasMoreTokens()) {

ar.add(PdfName.XYZ); //My case concern this part of the code

ar.add(new float[]{0, 10000, 0});

}

else {

String fn = tk.nextToken();

if (fn.startsWith("/"))

fn = fn.substring(1);

ar.add(new PdfName(fn));

for (int k = 0; k < 4 && tk.hasMoreTokens(); ++k) {

fn = tk.nextToken();

if (fn.equals("null"))

ar.add(PdfNull.PDFNULL);

else

ar.add(new PdfNumber(fn));

}

outline.put(PdfName.DEST, ar);

}

{…}

As you can see it is a simple management of my case.

If it can help you …

Best Regards,

Anne MUSSARD

> Hi,

> You say on your site about the SimpleBookmark class the

> following remarks:

> Bookmark processing in a simple way. It has some limitations,

> mainly the only action types supported are GoTo, GoToR, URI

> and Launch.

> The list structure is composed by a number of HashMap, keyed

> by strings, one HashMap for each bookmark. The element values

> are all strings with the exception of the key "Kids" that has

> another list for the child bookmarks.

> All the bookmarks have a "Title" with the bookmark title and

> optionally a "Style" that can be "bold", "italic" or a

> combination of both. They can also have a "Color" key with a

> value of three floats separated by spaces. The key "Open" can

> have the values "true" or "false" and signals the open status

> of the children. It's "true" by default.

> The actions and the parameters can be:

> * "Action" = "GoTo" - "Page" | "Named"

> o "Page" = "3 XYZ 70 400 null" - page number followed

> by a destination (/XYZ is also accepted)

> o "Named" = "named_destination"

> * "Action" = "GoToR" - "Page" | "Named" | "NamedN",

> "File", ["NewWindow"]

> o "Page" = "3 XYZ 70 400 null" - page number followed

> by a destination (/XYZ is also accepted)

> o "Named" = "named_destination_as_a_string"

> o "NamedN" = "named_destination_as_a_name"

> o "File" - "the_file_to_open"

> o "NewWindow" - "true" or "false"

> * "Action" = "URI" - "URI"

> o "URI" = "http://sf.net" - URI to jump to

> * "Action" = "Launch" - "File"

> o "File" - "the_file_to_open_or_execute"

> As you can see in my following PDF example, the action is a
