The gifplot example does not work straight out of the box,
I had to change ../Interface/gifplot.i slightly for java.
a)
The colors (e.g. BLACK) where defined as:
#define BLACK 0
and the functions expect 'Pixel color' where Pixel is a unsigned char.
#define constants contain no type information and are translated to integer
constants. Because of that, you have to cast every Pixel to a byte in java.
Changing the definition to:
const Pixel BLACK = 0;
fixes this.
b)
The definitions:
const PixMap *SQUARE = &PixMap_SQUARE;
const PixMap *TRIANGLE = &PixMap_TRIANGLE;
const PixMap *CROSS = &PixMap_CROSS;
don't work.
The wrapper code expects actual variables SQUARE, etc. and they are not
defined in gifplot.h.
c)
In shadow mode the method ColorMap::default() clashes with the reserved name
default.
