Hi guys,

I'm desperate for a good library or component that can convert pdf files to
tif and other
formats and vice versa.  I found Gnostice pdf2many activeX but it does not
do a good
job and is very slow.  Any of you have any recommendations ?

Thanks !

John Taylor

John,

The Envision image library ( http://www.intervalsoftware.com ) has
comprehensive TIFF support (Packbits, CCITT group 3, 1d and 2d,  
group 4, JPEG compression, Deflate compression, multi-page read
and write) and a TpdfGraphic  read/write format which works with PDF
files which are composed entirely of embedded images.

If you need to work with PDF files that contain formatted / searchable
text, it probably would not be what you need...

I haven't tested the TpdfGraphic format yet, but have used many
other features of the library (including the TWAIN  & multi-page
TIFF support) and have been very pleased with the value it
represented.

A trial version is available for download.  You get all the source
when you purchase & instructions on how to rebuild the units so the
trial branding is removed.  The most recent release is version 2.51,
for CBuilder 6 and Delphi 6, 7, 2005, 2006.  It integrates with TImage
does not use any external DLL's.

I have Envision also, but it will not convert a pdf to a tiff and other
graphic formats.

Thanks for the reply.

PDF2Tiff.exe

It's an exe, however. They do have a short example of how to call it
from Delphi (shellexecute).

just ran across it today while looking for form
creation/filling/annotation software...

====================
John,

Just a followup ... with the current version of the library (2.51)
the tpdfgraphic does indeed permit creation of a PDF from one
(or more) tiff images.  I made use of it the other day and it
works very well.  I'm setting up a web-based mechanism for
on-the-fly construction of PDF's built from multiple .tiff images
(scanned survey comments) selected via a query against a
table of comment / participant characteristics.

Nick,

Thanks for the reply but I meant to take a pdf and convert it to a
tif not the other way around.  I believe michel took (hmmm... I forget his
name)
his routines and incorporated them into version 2.51 and I already had
his library for despeckle, tifftopdf anyway.  Is michel still supporting
Envision ?  I rarely see his name on the message board anymore.

John,

The latest note from Michael on the support board was (I believe) 2/2/06 &
last website update was the 01/29/06 update for the 2.51 version that added
version support through Borland Studio 2006.

The only PDF -> TIFF (or other image format) conversion possible would
be from PDF's that were "image only" (i.e. ones made from only from
scanned/generated images ... no searchable/selectable text).  
For example, if you created a PDF directly from a scanned document
(with no OCR), you would be able to generate TIFF (or other
format) images from the individual PDF pages.  With the proper steps,
you could generate a multi-page TIFF.
