The most significant benefit is . Once converted, the image travels inside the DWG file. There is no risk of "Missing Xref" or "Image Not Found" errors when sharing files via email or cloud storage.
Standard approaches (saving a .tif and linking) break when files move or are shared. jtb raster2ole solves this by , embedding both pixel data and georeferencing inside the container. jtb raster2ole
| Limitation | Future Work | |------------------------------------------|------------------------------------------------| | Windows-only for full OLE read/write (IStorage) | Implement cross-platform via libole2 (Linux/macOS read-only initially) | | No built-in OLE host viewer (Excel/CAD must render) | Provide sample VBA/C# control for map interaction | | Large rasters (>500 MB) cause OLE container bloat | Add external tile referencing as fallback | | CRS transformation not applied during embed | Auto-reproject to target container’s native CRS if known | The most significant benefit is
: Works with various AutoCAD verticals including Architecture (ACA), Civil 3D, Electrical, Map 3D, and Mechanical. Standard approaches (saving a
is an essential third-party utility for AutoCAD users who need to permanently embed raster images—such as company logos, site photos, or scanned maps—directly into their .dwg files.
This paper outlines the technical necessity for such a tool, the workflow process, and the benefits of converting image references into embedded OLE data, particularly for firms standardizing drawing sets or moving to newer CAD platforms.
While JTB Raster2OLE is highly effective, users should be aware of the following technical nuances:
