Description:
------------
As you well know, coordinates in the southern
hemisphere or east of Greenwich are represented by
negative numbers.
I assume negative numbers should be used in setRange
arguments.
The image produced by the package presents a
"horizontally and verticaly flipped" (180 degree
rotated) image and only in the positive range of
coordinates (serious problem when a region crosses
equator).
Script used is the one used in the example on the home
page, but with a different data set (example below).
A space is not required before the minus sign (tried to
fix this in the E00.php parser).
Otherwise, it works great.

Reproduce code:
---------------
Sample of valid E00 data:
EXP 0 /AFS/PSU.EDU/LIBRARY/DCW/FTP/DCW_DATA/17245/RRLINE.E00

You can fix this bug quit easy.
In the file E00.php you find several times "[ -]([0-9]" change it to "([ -][0-9]". That's all.

Arno,
Thanks for the idea, but I don't think that it fixes
the problem. Or problems, to be more precise.
a- it still renders a flipped image (rotated 180 deg)
b- $map -> setRange needs to accept negative values
