This file format is not supported in the Imaging toolkits. Read and write support for this format is provided in the Document and Medical Imaging toolkits.
LEADTOOLS supports DGN versions 1, 2 and 3.
LEADTOOLS supports loading this format as a raster image, vector image, or SVG (Scalable Vector Graphics) document.
The file constants associated with this file format are:
| Constant | Read Support | Write Support | Description |
| IntergraphVector | Yes | Yes | Intergraph MicroStation and Interactive Graphics Design (DGN). |
When DGN files are rasterized, they are 24 BPP.
