DocView ?

DocView ?

[David A. Cobb]

[-- Attachment #1: Type: text/plain, Size: 1116 bytes --]

Recently attempting to edit an Adobe PDF file, I read up on the format 
and opened it into emacs (23.0.60.1 GTK+ as packaged in Ubuntu 
"emacs-snapshot.")  I expected to see the textual content: %PDF-1.6 .....
Instead, WOW! emacs actually rendered the document.

The mode-line says "DocView" mode, and I can switch back and forth 
between rendition and text.  I haven't yet found whether I can modify it 
and correctly render the changes.  Before I can do that, I will need to 
decode the content streams contained in the original.  Obviously (I 
think) the code is in there somewhere in order for emacs to render the 
thing.

Then, I tried finding something about this "DocView" in the Info 
system.  Sorry, no cigar.  Then I tried googling my way through gnu.org 
for something about DocView.  No joy there either.  Without some clue as 
to what I'm looking for, it is not likely I'll find it.  And, without 
some Info help, it is not likely I can get full use out of it.

So, please, where do I find the code libraries and the documentation for 
this capability?

TIA

,----[ (info "(emacs)Document View") ]
| DocView mode (`doc-view-mode') is a viewer for DVI, Postscript (PS),
| and PDF documents.  It provides features such as slicing, zooming, and
| searching inside documents.  It works by converting the document to a
| set of images using the `gs' (GhostScript) command, and displaying
| those images.

Maybe your snapshot it too old and doesn't include the docs.

Type "C-h f doc-view-mode RET", then click on the link to the sources
in the *Help* buffer, and read there.

Thank you much.  From the code comments, this appears to be a 
work-in-progress.  Is that so?

Not more than the rest of Emacs, I think.

As you say you use 23.0.60.1, then maybe yes.  And if your emacs doesn't
come with the info pages (info "(emacs)Document View"), then
definitively yes.  At that time it was work in progress.

Today (with emacs HEAD from CVS) it's quite mature, well documented and
usable.  Emacs 23.1 is coming...
