Problems writing images to PDF document

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am using an older version of iSed.dll (3/2/2004) .  

I am extracting the images from a multipage .tiff file into a standalone temperoray single image file. I am having problems writing images to the pdf document. I am reading the image from a single image file using AddImageFromFile. The smaller images (4KB) seem to write ok but larger (25KB) images dont get written to PDF doc. It seems as if the AddImageFromFile is reading it but ImageHeight and ImageWidth are 0. 

I tried to get iSEDQuickPDF.dll v 5.22 dated 1/3/07  from the download page but I cannot register it. I get an error saying that "dll is loaded but cannot be registered. No entry point for the dll".

Please help.

	Hi! I've answered already via mail but ... It's not necessary for dlls to have an entry point ... it's not a must. With version 5.21 i've made a lot of "tiff to pdf" samples and i don't have the problems you has described - even with "xx mb-images". Why do you work with single images? With QP you can get the multipage-tiff one time and then selecting each page. Perhaps you can post a snippet from your relevant code here and we can look on it ... Best regards, Ingo

	Hi! I've posted it here - so more than one can look on it ;-) I think there's something missing between assign iret and drawimage... First you had written that you're working with multipage-tiffs - in your syntax the pagenumber is missing. What means extension fim? ...Is tif behind? If "yes" take .tif and pagenumbers. There's no need for an offset then. Best regards, Ingo Here is my sample code..I am using v5.22 Activex dll. c:\Images.fim is a tiff file that contains multiple images. DEFINE iRet as integer. CREATE "iSED.QuickPDF" hQP NO-ERROR. hQP:UnlockKey("UnlockKey"). hQP:SetOrigin(1). hQP:SetScale(72 / 600). ASSIGN iRet = hQP:AddImageFromFileOffset("c:\Images.fim", 803723, 23125, 0). / Here iRet returns has a valid number which means it can load the image / hQP:DrawImage(600, 300, 1842, 813). / does not draw anything. When I try to display ImageWidth and ImageHeight they both are zero / hQP:SaveToFile("C:\test.pdf"). /when I open test.pdf. I get an error. "There was a problem reading this document (12)"*/ Could there be a problem with the image itself? But the image can be extracted and opened with other Image applications using same offsets.

	Sorry, it is not a multipage. fim is the file that contains all the images. It is a tif file but named as fim. I am not sure what you mean by *.tif and pagenumbers?

	Hi! You should read the documentation (it's in the library-section here). I'm a bit confused... it's not a multipage but it's a tif with all images inside. It's a tif buit the extension is fim...? Even if it's not a multi... you should try a "1" at "options". I don't know how QP check what type of image it is - if QP only checks the extension then that's the problem ... Perhaps you can try a further step using AddTIFFImageFromString ...? I think there's a lot to try for you ;-) Good luck, Ingo
