genOutput mishandles PIL

Anonymous — Tue, 15 May 2001 02:28:30 -0000

In utility.genOutput
the PIL branch needs to build the filename
the same way as for the VCR branch.

clipLines crashes because of improper ty

Anonymous — Fri, 30 Mar 2001 23:10:24 -0000

In __init__.py line 704...

for i in range(1,len(dataset)):
endpoints = [pts[i-1], pts[i]]
if clipLine(endpoints, bounds):
thisSegment = Line(endpoints[0], endpoints[1],
style=self.lineStyle)

should be changed to ...

for i in range(1,len(dataset)):
endpoints = Numeric.array([pts[i-1], pts[i]])
if clipLine(endpoints, bounds):
thisSegment = Line(endpoints[0], endpoints[1],
style=self.lineStyle)

Notice the Numeric.array call, since pts[] is set to a
list above here, the math and division using the lists
is not good.

The symptom is a crash if you have lines that actually
get clipped, i.e. lie outside the graph.

class Dataset incorrect type check

Anonymous — Fri, 30 Mar 2001 20:12:49 -0000

On line 174 (or so) for graphite __init__.py in
the class Dataset in __init__ were the lines....

def __init__(self, *data):
if len(data)==1 and (type(data[0]==TupleType) or
type(data[0]==ListType)):

to add NumericArray type and to fix up the parentheses
we changed it to...

def __init__(self, *data):
if len(data)==1 and ( type(data[0])==TupleType or
type(data[0])==ListType or
type(data[0])==Numeric.ArrayType ):
data = data[0]

The above incorrect line worked on Python 2.0 but not
on Python 2.1b2 .

TK and PIL fail as output options

Anonymous — Wed, 28 Jun 2000 19:11:30 -0000

If you change .../tests/testa.py to produce
a 'PIL' or 'TK' output instead of 'PDF',
then it bombs. Solaris 2.6, Tk/TCL 8.3.1.
Python 1.6a2+.
