problem with preview

[nywjn]

hello, I have a problem with preview .
my Configuration:

Code: Select all

system.ocr=C:\\jboss-4.2.3.GA\\moremodules\\Tesseract-OCR
system.openoffice.path=C:\\jboss-4.2.3.GA\\moremodules\\OpenOffice.org 3
system.openoffice.tasks=5
system.openoffice.port=2222
system.imagemagick.convert=C:\\jboss-4.2.3.GA\\moremodules\\ImageMagick-6.7.2-Q16\\convert.exe
system.swftools.pdf2swf=C:\\jboss-4.2.3.GA\\moremodules\\SWFTools

ERROR:

Code: Select all

IO exception executing command: C:\jboss-4.2.3.GA\moremodules\SWFTools -T 9 C:\jboss-4.2.3.GA\cache\pdf\59ab4fa5-d277-4943-83b9-f8fddad38679.pdf -o C:\jboss-4.2.3.GA\cache\swf\59ab4fa5-d277-4943-83b9-f8fddad38679.swf

Caused by: java.io.IOException: Cannot run program "C:\jboss-4.2.3.GA\moremodules\SWFTools": CreateProcess error=5, ???·?

What can I do, so that preview office documents will be available??

Tienes una configuración un poco estraña:

Esto :\\jboss-4.2.3.GA\\moremodules\\SWFTools debería ser algo asi como :\\jboss-4.2.3.GA\\moremodules\\pdf2swf.ese
y esto system.ocr=C:\\jboss-4.2.3.GA\\moremodules\\Tesseract-OCR mas de lo mismo, debería apuntar a un ejecutable.

Otro detalle a partir de la version 5.1.x recuerda que estas propiedades se deben modificar desde la base de datos.

Hi all.
I've just updated to 5.1.8-nightly and I lost my preview for SOME pdf documents. I uploaded a test pdf for OCRing and found that 5.1.8 doesn't show previews in the web browser. Says "There was a problem with conversion generation"

This is the output from the start.sh terminal screen when I click preview:

Hi，jllort ，thank you for your reply。I have other problem with dwg/dxf files。
Do you know how to realize this function？Thank you so much！！！
my configuration：
system.dwg2dxf=C:\\jboss-4.2.3.GA\\moremodules\\Acme CAD Converter\\AcmeCADConverter.exe

[jllort]

This extension is only available to our customers. If you want more information about it can contact with us at www.openkm.com/Contact

[Alexires]

So, no ideas why the previewer stopped working?

[jllort]

1- First try conversion to some doc to pdf if it runs the problem is on pdf2swf configuration, we'll be waiting the feedback

[Alexires]

Alright, I uploaded a .doc to OpenKM and then downloaded it using "Download as PDF Document" and it downloaded fine and worked. Hence, problem with pdf2swf?

Sorry it took me so long, have been flat out for a few weeks.

[jllort]

Yes, seems problem is on pdf2swf conversion tool. Test it directly from terminal, to see if there's some problem there.
Which pdf2swf version you've installed, and you're on 64 or 32 bits architecture ?

[Alexires]

Putting "pdf2swf -V" in the terminal yields the following:
"pdf2swf - part of swftools 0.9.1"

When attempting to convert one of the problem files (pdf2swf test.pdf -o test.swf), the following is given:

ERROR   ID Table overflow
ERROR   This file is too complex to render- SWF only supports 65536 shapes at once

[jllort]

Try with this parameters configuration -f -t -G -s storeallcharacters and I suggest take a look http://wiki.swftools.org/index.php?title=Pdf2swf

[Alexires]

Attempted using

Code: Select all

pdf2swf -f -t -G -s storeallcharacters test.pdf -o test.swf

and was given exactly the same error, however it stopped conversion at page 17 instead of page 24 like last time.

Still threw a ID Table Overflow.

[jllort]

try run with this paramters "-s poly2bitmap"

[Alexires]

Successfully outputted test.swf. Gave the following:

Code: Select all

 pdf2swf -s poly2bitmap test.pdf -o test.swf
WARNING fix bad advance value for char 0: bbox=1.00, advance=13.90

NOTICE  processing PDF page 3 (429x647:0:0) (move:-79:-74)

So, what's the plan from here?

[jllort]

In OpenKM administration change the pdf2swf for some pdf2swf .bat or .sh and put there your parameters the script will be called with two parameters ( if I'm not wrong ), that's the internal code

Code: Select all

String tpl = Config.SYSTEM_SWFTOOLS_PDF2SWF + " -T 9 ${fileIn} -o ${fileOut}";

I think this part is candidate to be changed, as we've done in ocr to specify all on administration data string, I've added the issue in http://issues.openkm.com/view.php?id=1887
