Added Postscript outout for measurements, plus assorted changes.
- postscript.c: added patterns backhatchpath and crosspath (for pad overlaid with solder paste) - postscript.c: added measurements - postscript.c: prefixed style parameters with PS_ to avoid future conflicts with gui_style.h - when changing the default unit, we now cancel the selection, and refresh canvas and current position - on-screen measurements now suppress the unit if set to anything but "auto" - use __attribute__((format(printf, ...))) for printf-like functions - the unit selector now has a white background to make it clearer that it can be clicked git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5461 99fdad57-331a-0410-800a-d7fa5415bdb3

@ -21,6 +21,10 @@ Style:
|
||||
- status area looks awful
|
||||
- add button with GTK_STOCK_UNDELETE for "undelete" to menu bar
|
||||
- edit names/values/etc. in place if possible
|
||||
- maximizing pad name size creates uneven text sizes. Particularly "1" gets
|
||||
excessively large.
|
||||
- pango_layout_get_size doesn't seem to consider rotation, so we currently
|
||||
don't properly size rotated text.
|

|

Bugs:
|
||||
- default silk width has no business being hard-coded in obj.c
