With PDFBox 2.0.0 this got much slower. So please find attached an example which you can use for profiling purposes. I used "OpenSans" TTF as the basis (grab it at https://github.com/google/fonts/tree/master/apache/opensans). > Beside it being slow, the created PDF cannot be opened (but this may have something to do with PDFBOX-2945 in RC2???) -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@pdfbox.apache.org For additional commands, e-mail: dev-help@pdfbox.apache.org
