[Gate-users] geant4 solids, interfile reader

[Patay Gergely]

Dear Gaters,

here are a few patches against the upstream (ie. master branch) Gate source 
code. Since I am not a member of the collaboration, I cannot directly commit 
them into the git repository.

The first patch was written by Dávid Völgyes (formerly at Mediso and at COMPET). 
These are C++ bugfixes (unchecked ranges, memory corruptions).

The second patch contains Gate wrappers to all the missing Geant4 solid objects 
from 
http://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/ForApplicationDeveloper/html/ch04.html 
.
With this patch the following extra shapes will be available: cut tube, 
elliptical cone, generic trapezoid, hyperbolic tube, parallelepiped, paraboloid 
tube, tetrahedron, torus, twisted box, twisted trapezoid, generic twisted 
trapezoid and twisted tube segment.

The third patch is a heavy modification of the Interfile reader. Besides some 
code cleaning and refactoring, it solves the following issues:
- if the key 'name of data file' is present in the header file then it won't 
guess the name
- the 'number of bytes per pixel' key (1,2,4,8...) is implemented
- the 'data offset in bytes' key is implemented
- the 'number format' key now accepts 'signed integer', 'unsigned integer', 
'short float', 'long float' and (for convenience) 'float', as seen in the 
Interfile 3.3 standard.
The interfile reader thus accepts signed or unsigned 8, 16, 32 or 64 bit integer 
as well as 32 (float) or 64 bit (double) floating point data from little or big 
endian binary file.
