Route styles are not properly loaded after nm conversion

[Milan Prochac]

The route styles ("Styles" item in .pcb file) are saved with unit specified (mil), but they are always read in cmils.

For example, 10mil line is saved as 10.00mil, when opened again the line width is read as 0.10 mil (10cmil), it is saved as 0.10mil and subsequently read as 0 ...

Applies to git HEAD.

Found the problem. The attached patch should fix it.

Hi Richard,
This seems to work without any side effects.
If in mm units parameters are written to pcb file in mm, if in mil they are written in mil, I didn't test for nm units (yet).
It looks like reading pcb files made with old releases (such as "example/LED2.pcb") keeps having problems loading the style parameters the first time (loads with errors, probably due to unitless parameters in the pcb file).
To solve this requires another patch.
Kind regards, Bert Timmerman.

Hi Bert,

The incorrect loading of route styles without units was a side effect of my patch, when there are no units detected s_len is set to 0 and therefore strncmp always returns 0.

I've fixed this and uploaded a new patch.

Hi Richard,
I can confirm that this latest patch works for me too.
Thanks, Bert Timmerman.

I can confirm too - works fine now.

Thank you
