Checking Program Version in Scripts

One of the problems with scripts is that Paint Shop Pro is not completely backwards compatible.  Between PSP X and X1, Corel changed the names of brushes, gradients and preset shapes.  Therefore, a script which works in X1 and X2 may not work correctly in 9 and X.  It is possible to have the script check for the program version and then switch between the old name for a brush, gradient or preset shape and the new name using an if statement.  The GetVersionInfo command returns the following keys: BuildType, MinorVersion, MajorVersion, MicroVersion, BuildNumber, VersionString and Program.

The following code snippet will provide the version of the program and place it in the variable 'version'.

   VersionInfo = App.Do(Environment, 'GetVersionInfo')
   version = VersionInfo['MajorVersion']

Insert the snippet after Do(Environment) at the beginning of the script.

def Do(Environment):

The variable 'version' can then be used to set variables for use in the script.  For example, to switch between custom brushes.

   if version == 9:
      brush = u'Marble2'
   elif version == 10:
      brush = u'Marble2'
   elif version == 11:
      brush = u'Corel_01_029'
   else:
      brush = u'Corel_01_029'

Then, replace the CustomBrush string in the brush command with the 'brush' variable.

    # PaintBrush
    App.Do( Environment, 'PaintBrush', {
            'BrushTip': {
                'Shape': App.Constants.BrushShape.Custom,
