HI all,

I have 3 pages scanned in PDF and I hope I can combine them into one big
jpeg image and post it online on forums.

The goals are:

1. Three pages cancated into one page(the height of the image is 3x
larger
than a normal image);
2. Do some annotation on this big image;
3. Convert everything into JPEG image file and then post it online on
forums...

The sniptool only allow no more than screen size capture.

Any convinient softwares that can fulfill the above requirement?

If I use a separate tool to combine the 3 pages into one big JPEG image,
the
sniptool does not allow opening a file to make annotations, that's too
bad...

---------------------

Currently I have the following software:

Acrobat Pro 7.0
Tablet PC XP Pro
Sniptool included when I buy the Tablet PC

I can also install the PHOTOSHOP, but I really hope there can be simple
solutions and in very few mouseclicks instead of using the bulky
photoshop... I don't want to load PHOTOSHOP to my poor-configured small
laptop...




Post the PDF ... making a mess out of a JPEG will be counterproductive.





If you post a pdf onto a public forum. You want people to view. The jpeg
version will be a natural way of presenting inside the browser; but a pdf,
it will propmt a window asking if they want to download or open, etc. esp.
if the browsers are not on Windows, but are on Linux, Unix, etc. They are
going to be reluctant of viewing pdf...

My purpose was trying to post pdf(full of math equations) and discuss with
those mathematicians over the Intnert forums...

Kiki,

All one has to do is create a link on the Web page to the PDF and it will
automatically open, if they have Acrobat reader. Other than the header info on
that browser window, they will not realize that they are looking at a PDF. On
my UNIX system's browser, PDF's open with no hesitation (other than the
request to "update" Acrobat!). Within the PDF, you can combine JPG and text,
with seamless efficiency.
