[Skencil-users] Scripted, command-line drawing example for Skencil 1.0alpha

[sdaau]

Hi all,

Just a small update - here is a more proper example script:

http://sdaaubckp.svn.sourceforge.net/viewvc/sdaaubckp/single-scripts/cmdl-blockdiag-fig-skencil.py?view=markup

.. which generates the following diagram:

http://sdaaubckp.sourceforge.net/post/img/cmdl-blockdiag-fig-skencil-r157.py.ps


While the block generation code can be a bit of a hassle to read, all I 
care for, is that I can issue commands like these to generate the "node" 
blocks:

	structNodeA = getStructBoxnode(
		"struct1",	# title label
		("*pnt1", "*pointer2", "*point3"),
		("var1", "variable2", "Varib3")
	)
	structNodeB = getStructBoxnode(
		"str2",		# title label
		("*pnt1", "*pnt2", "*pnt3", "*pnt4", "*pnt5", ),
		("var1", "var2", "var3", "var4", "var5", "var6", )
	)

... and the code will automatically resize and arrange a "node" block so 
it matches the text; and also, that I can issue commands like these:

  	tconnline = getStdConnLine(
		structNodeA[1]['ptfl_1'], # from (startpoint - moveto)
		structNodeB[1]['box'],	  # to (endpoint)
		({'-':30}, {'|':-50}, {'-':-40}, {'|':-50})
	)
	doc.Insert(tconnline)

... to connect the "node" blocks.


In any case - thanks again for making Skencil so versatile :)

Cheers!
