Short: Datatype for PovRay dump format (QRT)
Author: billy@uni-paderborn.de (Michael Böhnisch)
Uploader: billy@uni-paderborn.de (Michael Böhnisch)
Type: util/wb
QRT datatype 39.1 (first release)
---------------------------------
Datatype for PovRay dump format images (QRT style). Currently uses a
simple 24-to-8 bit conversion with static 3×3×2 (R×G×B) bit quantization.
QRT format is not easy to detect since there is near to no type specific or
constant information in the files PovRay creates. This release tests for
the following qualities:
· File size must match height and width information. Partial files
written by PovRay are rejected.
· Line numbers must start with 0 and increment to image height - 1 in
sorted order. QRT does not explicitly forbid arbitrary line order but
PovRay produces lines in sequence --- take it as a "feature", it really
makes file type detection easier and safer.
Installation: Simply copy the file Classes/DataTypes/qrt.datatype to
SYS:Classes/Datatypes and files Devs/DataTypes/QRT#? to DEVS:Datatypes and
reboot.
