Description Andrew Walker 2006-05-24 22:26:00 UTC 
Version:           HEAD (using KDE KDE 3.5.0)
Installed from:    Compiled From Sources
OS:                Linux

PROBLEM:
The line widths resulting from exporting a plot to a .eps file are much too large.

STEPS TO REPRODUCE:
Start kst
Create a plot with a curve
Select File... Export to Graphics File...
Select the EPS option and set the width and height to 500

RESULTS:
Line widths are much too thick

EXPECTED RESULTS:
The .eps file should appear approximately as on the screen
