Getting below exception while converting a ppt to PDF.Kindly advice for a solution.
Exception Message:com.aspose.slides.obfuscated.bri:
java.lang.UnsupportedOperationException: Cannot find the required font.
Name:"Dialog.plain", Style:0, IsExactStyle:false.
Hi Anand,
Thanks for inquiring Aspose.Slides.
I have observed the issue shared by you and suggest you to please try using Aspose.Slides for Java 7.8.0 on your end. If there is still an issue then please share the sample presentation, sample code, Java version used and Operating system details. Please also provide the custom fonts if used on your end. I will investigate the issue further on my end based on availability of requested information to help you further.
Many Thanks,
When I upgrade to 7.8.0 from 2.9.4 it shows many errors.Seems to be like may changes in the class in the jar files.Could you kindy convert the below code compatibile to 7.8.0.I am using Java 1.6.Hope 7.8.0 will work in Java 1.6.
