Fonts in Textfield and Highchart look different when exporting to PDF

[detlef.brendle]

Hi,

I have a custom font "Calibri" that is used on a Highcharts Subtitle element and on a plain text input field.

They look the same in Jasper Studio's preview, but when exporting into PDF they look different.

JasperStudio:

PDF export:

It seems that the PDF export has got different letter spacing for highcharts subtitle.

 

Can I control this behaviour somehow ?

Thanks,

Detlef

 

Here is the JRXML:

Hi,

You need to package up the Calibri font intro a JR font extension. Basically, the font needs to be available to the Java Virtual Machine that runs the JR engine.

Calibri is a Windows font and probably does not exist on the Linux/Unix machine where you run JR Lib and generate the PDF.

You can create font extensions in JSS and it would help you package up the TTF files as JAR files, to add to your application classpath.

I hope this helps.

Hi Teodor,

thanks for your answer.

I already create such a jar file and placed it on the classpath.

The fonts are also embedded into the pdf (as far as I can see)

Have you got other ideas?

Thanks,

Detlef

Hi Teodor,

 

I investigated a bit further, here my sightings:

- in Jasper server all seems fine - the title of the highcharts component look same than the plain textfield.

- when exporting to PDF things look different:

 

The highcharts component is rendered as image using phantomjs - right ? Seems that phantom is doing something with the font. Do I need to set some properties when rendering using custom fonts ?

 

Thanks,

Detlef

Hi,

There was indeed a bug in the way we deal with fonts while rendering the chart with PhantomJS.

This has been fixed now in the JR Library project and will be part of the next library release.

But you are using JasperReports Server and right now, I can't promise you when this fix will arrive in JRS.

Thank you,

Teodor

Hello,

I realize this is an old topic, but it describes exactly the same problem we are having when exporting reports to PDF through our application. The fonts in the body of the report appear fine, but anyplace we use those fonts in a Highchart, it gets replaced with a default font. This is causing display issues with long category names in the axis, etc. All of our fonts are in JAR files and aside from this Highchart issue, we've had great success implementing just about any font we want.

Should this have been fixed by now or no? Is there something different we need to do or set on the server?

Thank you,
Jeff
