    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

    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


    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

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

    Definitely, keep the PDF. You might want to include the link to Adobe's
    Acrobat Reader site, for those very few, who do not have it already. If Saved
    for the Web, I'll bet that the PDF will be much smaller than a JPG, and far,
    far more legible, as well. Acrobat Pro 7 will allow you to make all the
    annotations that you want, and keeping the form as a PDF will allow you to
    link directly from it to any other documents - maybe your annotations?

    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...

    Probably well over 90% of the people that view "things" on the Internet
    already know about Acrobat (PDF) files, and have the Adobe Acrobat Reader
    software (or the full Acrobat program) installed on their computer(s) ...
    and the other ten percent *should* have it. After all, The Acrobat Reader
    Software is well tested (well over a decade 'in the field'), essentially a
    'standard,' and completely and totally free. At this time *very* few users
    "are going to be reluctant of viewing pdf..."

    For your application, making any kind of JPEG image is a bad idea. JPEG is
    a *destructive* compression algorithm that is designed for continuous tone,
    or **photographic** images, and it can do some very *not* *nice* things to
    images that have sharp edges, such as text images (or, in your case,
    mathematical equations).

    Even more of a reason to use the PDF file(s) directly.

    You've received a bunch of crap advice here. I think the protesters don't
    realize that the original document isn't vector, but raster and besides,
    compressed ('optimized') PDFs are JPEGs.

    In any event, open Photoshop. File - New and make it as large as necessary
    to have all three pages concatenated (vertically, horizontally, whatever).
    Then in Photoshop open the PDF(s). Drag the image of choice into your New
    Document. Do the same for the rest. They will come in as separate layers.
    Drag them into the proper arrangement. Then save as .GIF (sharper that way).

    If the PDF images are messy, then use Levels or Curves to drop out the

    BTW - Unix, Linux, Mac, etc all have an Acrobat reader.

    Wrong. Totally wrong.

    You definitely need to investigate just exactly what a PDF file actually
    is. FWIW: The short answer is that the PDF file format is a (relatively
    minor) variation of the PostScript Page Description language, and its
    contents can be either vector or raster based.

    The graphics format used inside any given PDF file will depend upon the
    original used to produce the PDF file. For text or mathematical equations,
    it will definitely *will* be either a typeface (as in a font, or TTF, or
    OpenType) which is a vector item, or a vector drawing format such as an
    Adobe Illustrator drawing or an Adobe InDesign page layout file. Most
    probably, a mathematics expression would be created by an equation editing
    program, such as MathType or Equation Magic, and most likely would be in a
    vector Encapsulated PostScript File (EPS or EPSF) format.

    PhotoShop is *not* the program of choice for working with those kinds of
    illustrations. JPEG is also *not* the file format to use for document

    OP specifically stated that these were SCANNED pages.
    Unless his scan software does an OCR equivalent for mathematical layout,
    wouldn't that be raster?

    I've downloaded too many "PDF" documents that were just megabyte raster
    scans of pages that had a few hundred characters on plain white,
    encapsulated as pdf files.

    You have not determined what his source file is. I presumed it was a raster
    image, thus my comment.

    Yes it would. Other than his "you had better learn" comment, RSD99's
    information was good for others like himself who may have misunderstood the
    OP's situation.

    RSD - No problem. Good post.

    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.
