Exceptions

See Example 28

If the library is not able to calculate and position all the frames it will throw an exception. This happens also if you create a circular dependency in your report tree structure. Another problem is if you add an ImageFrame with invalid image file (no access or not an image). Therefore, you should catch exceptions when you call the output function like in the following example.

from PDFReport import *

 report = Report()
 body = report.body

 # Endless loop
 box1 = BoxFrame(body)
 box1.add_frame(body)
 try:
     filename = "/output_28"
     report.output(filename, True)
 except OverflowError as error:
     print(error)
