"""
Converts a tile set from bmp to png for use with the Mac OS X frontend.
Usage
python osx_bmp2png.py input_file output_file [options]
Options
--tcoord hcoord vcoord
Reads the color to be treated as transparent for non-terrain tiles
from the position (hcoord, vcoord) in the tile set. Both coordinates
are non-negative integers indexed from zero. Is overridden by
--transparent if that option is set. When not set, the default is to
read the color to be treated as transparent from (0,0).
--terrain lx1 ly1 ux1 uy1 ...
Sets bounding boxes for parts of the tile set that are to be treated
as completely opaque (i.e. as background terrain). Each bound box is
given by the coordinates for the lower corner, (lx,ly), and upper
corner, (ux,uy), with ux > lx and uy > ly. If not set, the default
is to use two bounding boxes, (0,0) to (496,16) and (192,192) to
(224,208), which are the terrain tiles in Michrochasm's tile set.
--transparent red green blue
Sets the color, as RGB values between 0 and 255, which will be treated
as completely transparent for non-terrain tiles. If not set, uses
--tcoord or its default to get the color.
Example
This is the conversion that was used to ready Microchasm's tile set for
the OS X front end:
def _dot(x,y = (float,float)):
numpy = getattr(_numpy,'dot')
cv = getattr(_cvisual,'dot')
if type(x) is vector and type(y) is vector: return cv(x,y)
return numpy(x,y) # arrays rather than Visual vectors
def _uf(x,y,
numpy = getattr(_numpy,ufunc),
math = getattr(_math,ufunc),
mathtypes = (float,int,int)):
if type(x) in mathtypes and type(y) in mathtypes: return math(x,y)
return numpy(x,y)

To calculate the minimal bounding # is not trivial and usually the Axis Aligned Bounding Box (AABB) does not show up the real dimensions of the protein. This script calculates the inertia tensor # of the object, extract the eigenvalues and use them to rotate the molecule (using as rotation matrix the transpose of the eigenvalues matrix). The result is that # the molecule is oriented with the inertia axis aligned with the cartesian axis. A new Bounding Box is calculated that is called Inertia Axis Aligned Bounding Box #(IABB), whose volume is always lower than AABB volume, and in many cases will correspond with the lowest volume. Of course, maybe it exists another Bounding Box # with a lower volume (the minimal Bounding Box). # # As always with these type of things, you have to use at your own risk. I did not try all the possible combinations, but if you find a bug, do
