What the original poster would like to accomplish is, I believe, nicely
accomplished in an AIR application that uses the PurePDF actionscript
library in preference to the AlivePDF library. If you visit both sites and
spend a little time reviewing the issues at both of them, you may think that
PurePDF is better supported. Having tried to work with both, it was my
experience that because the PurePDF library started with a more
comprehensive intent to port the features from the very comprehensive iText,
Java implementation it delivered more. That said, I suppose you would care
less about the comprehensiveness of the library as long as whichever one you
chose provided the specific facilities you need. Essentially that boils
down to reading an existing PDF more than producing a new one, which is the
primary problem that both projects originally set out to solve.
Since that was also my primary interest, I can tell you that in terms of
producting full-featured PDF documents, PurePDF wins hands down over
AlivePDF. In terms of reading and exracting content -- specifically jpeg
images -- since my applications do not need to do that, I cannot give you a
first-hand experience. Instead, in reading your posting, I just went to the
site and tested the sample program that compiles right out of the box and
demonstrates such an extraction of a jpeg image from a test document. I am
pretty certain you could just point the sample program to your own PDF file
and it would successfully extract all jpeg files for you..

Hi Lucas and all... (I am new to the group and thought I would take a stab
at your ?)
Re: convert PDF to pages.
Not sure how to approach this inside a FLEX/AS3 app -- but I do know how you
can do it offline using ImageMagik
If interested in this approach, Install Imagemagik for your platform then
issue a convert command similar to the one below (like this depending on
your general needs),
Example:
Home:\ or C:\ or ... convert.exe
c:\xampp\htdocs\bookdrop\test.pdf -units PixelsPerInch -colorspace
RGB -density 900x900 -quality 90 c:\xampp\htdocs\assets\%%d.jpg
Will pick apart a PDF and make test00.jpg, text01.jpg etc etc
All for free... I presume convert has a switch of some sort to go from
PDF -> single-image if that's what you need/want.
Obviously not flex/air related, but depending on your environment, perhaps
you can logically kick off some sort of System("convert.exe . . . ") let the
outside process perform what you need, and read in the IMG using something
like StageWebView(), upon a completionEvent of some sort.
Just a thought Cheers //GH

Subject: use flex to create picture (JPG or PNG) files from a PDF?
Hi, is there a way to use flex to open a PDF file and save its contents (all
pages) as picture files? I was looking for some solutions like opening the
PDF with the HTMLLoader class or use some libraries like alivepdf but didn't
get good results...
