DXB Driver Custom Properties

Specifies custom properties for plotted DXB files.

  • It produces 16-bit integer DXB files containing only vectors.
  • DXB output is monochrome; all vectors are color 7.
  • Raster images and embedded OLE objects are not supported.
  • The driver ignores object and plot style lineweights.

Use the Custom Properties dialog box to set the maximum resolution of the DXB output. Because 16-bit DXB files have a limited coordinate space, the highest resolution settings are only available for smaller "paper" sizes. If you select a high value for maximum resolution and then select a large paper size (for example, ANSI E), a warning is issued indicating the resolution was reduced to accommodate the large plot size.

The resolution control primarily influences the tessellation level of objects. If you set the resolution to a low level, arcs, circles, text, and so on, will be drawn with less tessellation, while at higher resolution settings, more tessellation segments are generated, which creates a larger plot file.

Entities such as solids and lines with thickness are stroked with line segments that have a single-dot width. Decreasing the resolution decreases the number of segments needed to fill these entities and reduces the DXB file size.

This DXB file driver does not plot raster-image entities. The driver plots an outline rectangle instead.
