Basic ideas for a package format for piddle:
|
|
|
|
1. Name change
|
|
--------------
|
|
Provisionally, I'm using the name "sping" for Simple
|
|
Platform Independent Graphics . If someone has a better idea, I'm happy to
|
|
use it.
|
|
|
|
2. Package Structure
|
|
--------------------
|
|
A. Canvas template
|
|
|
|
piddle.py -> sping.pid # "pid" will stand for Plug In Drawing
|
|
-> colors.py # colors have been separated although sping.pid does a
|
|
"from colors import *"
|
|
|
|
B. Backend renaming
|
|
piddleXY.py -> sping/XY/pidXY.py # backends are all capitals "XY"
|
|
OR
|
|
sping/XY.py
|
|
|
|
# It might be a bad idea to have two different ways to specify backends. Comments?
|
|
|
|
|
|
For users, you can always get the XYCanvas by doing:
|
|
|
|
> from sping.XY import XYCanvas # should also work
|
|
|
|
In addition
|
|
|
|
> from sping.XY import * # should expose a XYCanvas
|
|
|
|
|
|
C. Backend helper files (e.g. pdfdoc.py)
|
|
Are placed under the backend subdirectory, for example:
|
|
|
|
piddle/pdfdoc.py -> sping/PDF/pdfdoc.py
|
|
|
|
|
|
D. Other directories:
|
|
|
|
sping/*.py -> core pid.py and any other core classes/utilties exposed to user
|
|
|
|
sping/lib -> contains code useful to all backends. Examples: bezier geometry code,
|
|
coordinate transformation code
|
|
|
|
sping/util -> tools and other useful classes
|
|
|
|
sping/exapmles -> instructive examples for using various backends
|
|
(perhaps should be in separate doc distribution?)
|
|
|
|
sping/tests -> place all verification tests here
|
|
|
|
|
|
sping/contrib -> a stub directory where people can add their own code and contributions from
|
|
others that may not yet belong in the core yet
|
|
|

|
PIL usage
|
|
--------------
|
|
|
|
PIL is now used as a package. I have added a patch to PIL to enable to it
|
|
to support all. I am making a win32 (known to work on Windows NT 4)
|
|
available from the piddle web site.
