Error Messages

Not Applicable

Steps to Reproduce

1. Create an activity that calls "HTMLTOPDF" activity.
2. Run the activity that generates a report that contains "Korean" or any other fonts.

Root Cause

It is observed that along with "ms mincho" font, other required font files should be available to PD4ML library to render unicode characters in PDF.


By placing the fonts in the correct server instance, and setting the values of the properties pyPDFFontDirectory, pyPDFEmbedFont, pyPDFPropsDirectory in the activity which calls HTMLtoPDF, the issue gets resolved.

Following are the steps, which need to be followed to address the current issue:

1. Place the font file in temp directory in server instance.
For example: /Users/Documents/Pd4ML/pd4fonts
2. Set the below parameters in parameter page before invoking the HTMLTOPDF activity.

Note: For more info regarding the font resolution process, refer pd4ml web site or see:
