- 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.
