Draw a colored Bezier curve with transparent background?

[pstein]

Assume I have an existing diagram. Now I want to draw a colored Bezier curve (=arrowed line) with transparent background into this diagram.

I did the following (in PSP X2 !):
- In Tools toolbar I activated the "Pen tool"
- In tool options a marked "Bezier curve" style
- In "Materials" pane I set foreground to blue color and background to white
- Then I draw the line

Unfortunately PSP covers automatically after completion the full "inner" bezier pane with the white background color.

I don't want this.

Therefore I have to tell PSP somehow to NOT auto-fill out the inner area or fill it out with transparent color.

How can I achieve this?

Thank you
Peter

" In "Materials" pane I set foreground to blue color and background to white"

Does In "Materials" pane I set foreground to blue color and background to transparent work?
