I am trying to convert html to pdf via setting HtmlOptions.

Its work in Windows, but It fails in Linux enviornment.

I even tried to set the page width and height, and also made -Djava.awt.headless to true. also Set the enviornment properties for the same, and it didnt work. Its giving same exception again.

I am using Latest Aspose PDF 9.7.0 - JDK 1.6 jar

I tried to load the Sample HTML file but its not allowing to load in this forum. Can you please help me over this.

Thanks,

Jagat
