DL is a raster-oriented animation format created by Davide Tomè and Luca De Gregorio. It is associated with the DL MAKER (also written DL-MAKER) and DL VIEWER software for DOS.

There are three major versions of the format (v1, v2, and v3).

Software

• DL MAKER - DOS software, distributed as shareware.
  • v3.0
  • [1] → "DLMAKE31" - v3.1
• DL VIEWER - DOS software for playing DL files, and converting to newer format versions. Shareware (v3.x) or freeware.
  • v2.3
  • v3.1
  • Source code
• Atari Computer DL Viewer
• dltogl - A utility to convert DL to GRASP GL (only supports v2 format, and only a subset of that)
  • DLTOGL.ZIP - Original (DOS binary + source code)
  • Amiga port
• GraphicConverter
• XAnim

Ed. note: Some of the DL MAKER and DL VIEWER programs listed above have a hard-coded expiration date. Suggest using a DOS emulator that lets you change its clock.
