I am converting lotus notes document library inline images to gif images using dxl

  • 0

I am converting lotus notes document library inline images to gif images using dxl logic of reading Filedata and converting it to base64 byte[] and creating a gif images. The conversion was working fine for all the sample but few days back we came across sample file with notesbitmap tag, after reading few forums it was mentioned that

“For the problem images in your DXL export, do they result in a element in the output, or a ? If the latter, I believe they are actually image references instead of actual images; the notesbitmap data is not a gif, but contains a binary header and URL in a Notes-specific format.”

But where can i find the URL in notes specific because when i decode the second data it gives me garbage result instead of url.

I also tried setting the ConvertNotesBitmapToGif .net property to true before conversion.

Please find the below link for sample DXL:
http://www.page-monitor.com/Downloads/Exported2.xml

Details:

xP8gAAEAAQAAAAgAAAAAAAAAAAAAAAAAU1RHNjI2NTeVACYAAAAAAAAAAAAAAAAAAAAAAAAA0wF/
AAAAAAAAAAAAAAAAAA==

is the header info i.e image name

and filedata below at the bottom
should give the URL (as per the Lotus notes forum)

Any help will really be appreciated!!

Thanks and Regards

    From http://publib.boulder.ibm.com/infocenter/domhelp/v8r0/index.jsp?topic=%2Fcom.ibm.designer.domino.main.doc%2FH_NOTESBITMAP_ELEMENT_XML.html

    notesbitmap element

    Represents a proprietary Notes bitmap image. Images stored in an NSF
    file are comprised of base64 content, which is a series of CD
    (composite data) records representing a bitmap.

    Therefore, if you run

    xP8gAAEAAQAAAAgAAAAAAAAAAAAAAAAAU1RHNjI2NTeVACYAAAAAAAAAAAAAAAAAAAAAAAAA0wF/ AAAAAAAAAAAAAAAAAA==

    though a base64 decoder, you get

    `Äÿ ������������������STG62657�&�������������������Ó�������������

    And you will find “STG62657” further down in the DXL

    <item name="$FILE" summary="true" sign="true" seal="true">
<object>
<file hosttype="cdstorage" compression="none" flags="storedindoc" encoding="none" name="STG62657" size="2332">

    Which you can decode ….
