DGN (also RDL) is a file format common to Intergraph's MicroStation and Interactive Graphics Design System (IGDS) CAD applications running on Intergraph workstations and PCs.
This file format is not supported in the Imaging toolkits. Read support for this format is provided in the Document and Medical Imaging toolkits.
LEADTOOLS supports DGN versions 1, 2 and 3.
The file constants associated with this file format are:
| Constant | Read Support | Write Support | Description |
|---|---|---|---|

When DGN files are rasterized, they are 24 BPP.
