1.2.3.1. Converting HTML to PDF
Reports which have a template in HTML format and the PDF output format do not always properly display fonts. To resolve this, add cuba/fonts
subdirectory with required .ttf
fonts to the Middleware configuration directory (tomcat/conf/app-core
in default deployment configuration). Additionally, you can use existing operating system fonts by specifying their path in the reporting.fontsDir application property.
In order to resolve the fonts issue on a Ubuntu server, you should do the following:
-
Install the
ttf-mscorefonts-installer
package:$ sudo apt-get install ttf-mscorefonts-installer
-
Set the reporting.fontsDir application property:
reporting.fontsDir = /usr/share/fonts/truetype/msttcorefonts
-
Explicitly specify fonts in HTML templates, for example:
<html>
<head>
<style type="text/css">
* { font-family: Times New Roman; }
</style>
Another thing to mention is parsing of special characters. To avoid errors when converting HTML to PDF, it is recommended to wrap your fields in <![CDATA[ ]]>
construction in your HTML template file:
<tr>
<td> <![CDATA[${(row.fields('book_name'))!?string!}]]> </td>
<td> <![CDATA[${(row.fields('author'))!?string!}]]> </td>
</tr>
