Excel(.xls), Power Point (.ppt) and Tiff Image(.tif) Previw

 #24792  by Muhammad Imran
 
Hi,
I have installed OpenKM 6.2.2 on windows XP. I have configured it to replace HSQLDB with MySQL. Right now, in OpenKM .png .jpg .docx .txt .gif etc. preview is working well but the preview of files with extensions .tif, .ppt and .xls is not working.

when I want to preview .xls, I see the following error:
Conversion: Error in application/vnd.ms-excel to PDF conversion

when I want to preview .ppt, I see the following error:
Conversion: Error in application/vnd.ms-powerpint to PDF conversion

when I want to preview .tif,I see the following error:
Conversion: Error: May not be a PDF file (continuing anyway)
Error: PDF file is damaged - attempting to reconstruct xref table...
Error: Couldn't find trailer dictionary
Error: Couldn't read xref table
I have installed and configured the following softwares:
1. Imagemagic
2.swftools
3.tesseract
4.openoffice

I have also checked my configurations in the administration -> configuration -> configuration chek
My OpenKM configurations are also OK.

I also check on command line the imagemagick converts .tif to pdf successfully.
Code: Select all
convert *.tif imagenes.pdf
Please tell me where i am wrong...!
Thanks in anticipation,

i suggest take a look here:
http://wiki.openkm.com/index.php/Previsualization

To ensure soffice is correctly running, simply add text file into openkm and then try to download as pdf ( toolbar option ) if it's right then soffice service is correct otherside there's something wrong there.

Take in mind depending your ms office version can not be opened by openoffice, anyway openoffice ( or libreoffice ) service is first step manadatory to preview document.

Thanks for reply,
I can download the .txt file into .pdf file successfully. Now the .ppt and .xls preview is also working but the .tif preview is still not working.
I tested with scanned balck and white .tif image at 300 dpi, On uploading a new .tif image in OpneKM I can see the following error message:
Conversion: Document can not be opened
Please guide me to fix this problem.

When I tried to preview the .tif image , I can found the following error messages loged in $TOMCAT_HOME/logs/catalina.log file.
