Support team,

I am trying to convert DWG file to DXF using java code. My java code is working fine in WINDOWS but it is failing in Linux environment with below error
“Fontconfig error: No writable cache directories”

Here is the java code snippet.

ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
Image image = Image.load(multpartFile.getInputStream());
DxfOptions options = new DxfOptions();
CadRasterizationOptions cadRasterizationOptions=new CadRasterizationOptions();
cadRasterizationOptions.setDrawType(CadDrawTypeMode.UseObjectColor);
options.setVectorRasterizationOptions(cadRasterizationOptions);
options.setOutputMode(CadOutputMode.Convert);
image.save(outputStream,options);

Please provide the inputs to proceed further.

@shivanandtripathi,
Hi,
this seems to be related to the user access rights for the work with system fonts.

Hi, Do we have some workaround to resolve this fontconfig error by using java code ?
Please suggest.

@shivanandtripathi,
this seems to be not related to code. Please try to increase user rights. It this will not help it could be useful for us if you create some simple project with this code so we can just run it in the same way as you and observe the error.
