Hi Peter C, and B,
when zoomed way in I have some drawing artefacts in the net mode.
The net mode uses the variables second_x, last_x, start_x to spezify the
invalidate rectangle:
---------
o_invalidate_rect(w_current, w_current->last_x, w_current->last_y,
w_current->second_x, w_current->second_y);
---------
This function call does not take care of the width of the net line.
Possible fixes for the problem:
* the caller calculates the correct rectangle
This has to be done many times and requires sorted coordinates
of the rectangle.
* add an extra function parameter to o_invalidate_rect for extra margin
* add some extra margin depending on the current line-width of the
current graphic contexts inside o_invalidate_rectangle. (w_current->gc
and w_current->xor_gc)
What are your opinions?
Regards
Werner
