+% sdl.ps - SDL shapes for Graphviz/dot in PostScript output mode |
|
5 |
+% |
|
6 |
+% USE |
|
7 |
+% All procedures expect to be passed a rectangular bounding box in the |
|
8 |
+% order [upper right, lower right, lower left, upper left, upper right]. |
|
9 |
+% All procedures expect to be used with "peripheries = 0". |
|
10 |
+% |
|
11 |
+% BUGS |
|
12 |
+% The following shapes are currently not implemented: |
|
13 |
+% - frame/system/block/process/procedure/service/procedure, and types thereof |
|
14 |
+% - macro inlet/outlet/call |
|
15 |
+% - exception handler/handle/raise |
|
16 |
+% - decision (suggest use diamond) |
|
17 |
+% - alternative (suggest use triangle) |
|
18 |
+% - internal input/output (suggest stop using historical relics!) |
