Hi, ya all.
Cameron Smith and Nancy Blachman reported several
graphics bugs in their book, here I'll add one more.
-----------------
When a circle is way larger then the PlotRange, there is a problem.
The one below will beep. The error dialog
says something about a PostScript error.
Show[
Graphics[
Circle[{0,0},20], PlotRange->{{0,6},{-1,1}}
]
]
This problem is especially annoying. I am writing a program that will
plot osculating circles of a curve, this bug made it impossible.
-----------------
FullOptions do not return explicit
value for some options.
(this is mentioned in Smith/Blachman book, p.292)
ParametricPlot[{t, Sin@t}, {t, 0, 6 Pi},
AspectRatio->Automatic,
Background->GrayLevel[.8], Frame->True
]
FullOptions[%, { ColorOutput, DefaultColor,PlotRegion }]
----------------
