Arrow Script

I think that there are errors in the changed script - the order of the options in the SF-OPTION parameters "Length of wings type" and "Brush thickness type" have been swapped to put the absolute pixel values before the ratio-metric settings but the constants FACTOR_RELATIVE_TO_PATH_LENGTH and FACTOR_IN_ABSOLUTE_PIXELS still have the original values (0 and 1 respectively) - this means that the program code will be using ratio-metric values when the UI is indicating that absolute values are being used and vice versa.

The SF-ADJUSTMENT parameters "Length of wings (LoW)" and "Brush thickness (BT)" have had their settings changed but the new values will be used as ratio-metric ones if using the default settings of the script (which I guess wasn't the intent).

Note that these comments apply to the arrow-set-size.scm and arrow-set-size-samj.scm scripts as posted earlier in this thread - they may have been edited since.

The corrections needed are to restore the two SF-OPTION lines back to their original forms i.e.

Code:

SF-OPTION      "Length of wings type"            (list "Path length divided by LoW value" "LoW Pixels")

SF-OPTION      "Brush thickness type"            (list "Path length divided by BT value" "BT Pixels")

This will correct the UI display and still give you the same results.
