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.
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|
|FILE_INTERGRAPH_VECTOR||Yes||Yes|| Intergraph MicroStation and Interactive Graphics Design.|
When DGN files are rasterized, they are 24 BPP.
The following table indicates which objects LEAD can load and which objects it can save:
|Arc||Supported||Not Supported. Saved as polyline.|
|Ellipse||Supported||Not Supported. Saved as polyline.|
|Lines||Supported||Not Supported. Saved as polyline.|
|Elliptical Arc||Supported||Not Supported. Saved as polyline.|
