DGN (DGN)

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 Pro toolkits. Read 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 raster image, vector or SVG (Scalable Vector Graphics) document.

The file constants associated with this file format are:

When DGN files are rasterized, they are 24 BPP.
