Qcad .dwg files preview on alfresco

Dear Team ,

I had setup qcad integration for .dwg files with alfresco as per below,

1. Changes done in alfresco-properties file

### External executable locations ###
ooo.exe=/opt/alfresco-community/libreoffice/program/soffice.bin
#ooo.exe=/usr/bin/soffice
ooo.enabled=true
ooo.port=8100
#img.root=/opt/alfresco-community/common
img.root=/usr/local/bin
img.dyn=${img.root}/lib
#img.exe=${img.root}/bin/convert
img.exe=convert
alfresco-pdf-renderer.root=/opt/alfresco-community/common/alfresco-pdf-renderer
alfresco-pdf-renderer.exe=${alfresco-pdf-renderer.root}/alfresco-pdf-renderer

jodconverter.enabled=false
jodconverter.officeHome=/opt/alfresco-community/libreoffice
jodconverter.portNumbers=8100

# QCAD Configuration Properties #
transformer.strict.mimetype.check=false
dwg2pdf.root=/home/ubuntu/opt/qcad-3.23.0-trial-linux-x86_64

content.transformer.dwg2pdf.priority=50
content.transformer.dwg2pdf.extensions.dwg.pdf.supported=true
content.transformer.dwg2pdf.extensions.dwg.pdf.priority=50
content.transformer.dxf2pdf.priority=50

content.transformer.dxf2pdf.extensions.dxf.pdf.supported=true

content.transformer.dxf2pdf.extensions.dxf.pdf.priority=50

2. I have add mimetype file name as mimetypes-extensions-map.xml

<alfresco-config area="mimetype-map">

<config evaluator="string-compare" condition="Mimetype Map">
<mimetypes>

<mimetype mimetype="image/vnd.dxf" display="DXF Mimetype">
<extension>dxf</extension>
</mimetype>

</mimetypes>
</config>

</alfresco-config>

3. add 3 files into extension folder,

for that please refer attchement.

after adding this i restarted alfresco and tomcat,

But when i load dwg files, pdf content could not load error was occuring?

i dont know why this error ,

4. One another question is imagemagic required for .dwg file preview?

beacuse we are using common for pdf rendering.please suggest?

Re: Qcad .dwg files preview on alfresco

Dear Sanjay,

I had tried this. but still pdf content not loading error was occure.

as i mentioned it is necessary to use imagemagick library for pdf rendered because we are using common for that

and if it necessary then how to configure imagemagick with alfresco which is on ubuntu os?

Please suggest

Re: Qcad .dwg files preview on alfresco

Just try to disable OOTB transformers by adding following properties in alfresco-global.properties file.

content.transformer.double.ImageMagick.extensions.pdf.tiff.supported=false

content.transformer.complex.PDF.Image.extensions.pdf.tiff.supported=false

content.transformer.ImageMagick.extensions.pdf.tiff.supported=false

content.transformer.PdfBox.extensions.pdf.txt.supported=false

content.transformer.TikaAuto.extensions.pdf.txt.supported=false

Re: Qcad .dwg files preview on alfresco

I was getting the same issue when I applied the OCR. So I found that it was conflicting with the existing transformers and I disabled it using the above properties and it is working now.

Can you share the error logs?

Re: Qcad .dwg files preview on alfresco

OOTB transformers are available with Alfresco installation by default. You don't install anything additional. 

As Kintu mentioned just try adding the above given properties in your alfresco-global.properties file and see if it works.

Dear Abhinav,

I have already added into global-properties but still it doesn't work.
