    Default CFContent & Images

    We have a problem that is RAPIDLY becoming a very serious issue. We have a
    report that is displaying a number of charts in JPG format. this report is
    then created in a PDF format using the cfdoent tag, and the pdf is emailed
    to a number of people. This is where the problem comes in.

    The JPG charts in the PDF file - randomly - are displayed HUGE, and out of
    proportion. When I say random, I mean that when a pdf file is generated, we
    have no idea whether it will be correct or not. All emails of a single pdf
    file either work, or they don't. PLEASE HELP ME. We're going to lose a client
    due to this issue!

    I'm sorry - I happened to have CFContent on the brain. The tag I am actually
    having an issue with is CFDoent. When I generate a PDF file, there seems to
    be about a 70% chance that the images within that PDF file will not be
    displayed correctly, but will rather be n up so large that you can only see
    the top left corner of the image. Its literally killing us!

    Similar issues here. We are trying to put an image into a CFDOENT.
    Sometimes the image fully renders and sometimes it gets cut off. We've even
    tried to put width="150" in our html IMG tag....but the results are always
    unpredictable. In fact, if I limit the width of the image, I still get an
    image that is cut off.

    Adding a GetTickCount at the end of the image string looked like it was going
    to work....but after a couple of tries, the results ended up being the same.
    (In a newsgroup, someone had suggested that CF was rendering the PDF faster
    than the image could be inserted. So they suggested tacking on some kind of
    function, such as GetTickCount, that would have to be computed and, therefore,
    "slow down" the rendering engine a bit.)



    <cfdoent format="FlashPaper" pagetype="letter" marginbottom="0"
    margintop="1.5" marginleft="1" marginright="1">
    <cfloop query="Get_Vendors">
    <cfset body = TRIM(Replace(Get_letters.body, chr(10), '<br>', 'ALL'))>
    <cfif Get_Letters.sig neq "">
    <cfset body = TRIM(Replace(body, '<signature>', '<img src="/sigs/' &
    URLEncodedFormat(Get_letters.sig) & '?id=' & GetTickCount() & '"
    width="150"><br>'))>
    <cfelse>
    <cfset body = TRIM(Replace(body, '<signature>', ''))>
    </cfif>
    <cfoutput>
    <div style=" font-size:10pt; font:'Times New Roman', Times, serif;
    width:auto ">
    #DateFormat(Now(), "mmm dd, yyyy")#<br>
    <br>
    #Get_Letters.name#<br>
    #Get_Vendors.name#<br>
    #TRIM(Replace(Get_Vendors.address, chr(10), '<br>'))#<br>
    #Get_Vendors.city_state_zip#<br><br>
    #body#
    </div>
    <cfdoentitem type = "pagebreak"/>
    </cfoutput>
    </cfloop>
    </cfdoent>
