Raster Manager Enhancements

There are enhancements to raster references functionality in MicroStation V8 2004 Edition.

Moving, rotating, and scaling raster references

The 2004 Edition extends raster reference manipulation capabilities with the addition of the following tools:

Move Raster
Rotate Raster
Scale Raster

These tools are in the Raster Control tool box.

Clipping

Closed B-spline curve have been added as a valid element to define a raster clipping boundary or clipping mask.

Enhanced 3D functionality

The Modify Raster, Move Raster, Scale Raster, and Rotate Raster tools support operations on raster images not positioned in XY plane. For these operations, you can set the rotation and affinity angles.

Raster Manager dialog box enhancements

In MicroStation V8 2004 Edition, the Raster Manager dialog box has these enhancements:

The new GeoPriority column allows full control over the reading of the georeference of the raster: through the DGN attachment, through a worldfile, or directly from the raster header. Color coding helps you visualize the origin of the raster's georeference. Each image file can have a different GeoPriority.
The On-the-Fly column indicates if a raster is reprojectable in a DGN file to which MicroStation GeoGraphics has added a coordinate system.
The Coordinate System column indicates if the coordinate system in which the raster is projected is inherited from the DGN to which it is attached or if it has been read directly from the raster header. This column is only visible when MicroStation GeoGraphics 2004 Edition and higher is loaded.
The lower section of the list box has changed.

Enhanced attachment settings

The following attachment settings allow full control of raster geolocation:

Coordinate System tab (requires MicroStation GeoGraphics 2004 Edition)
Geotiff tab
GeoPriority list box (on the Location tab).

Enhanced raster reference

The foreground color of a binary raster file can now be selected in the Attach Raster Reference dialog box. The raster preview will reflect the foreground color selected. It is also possible to attach the binary raster file with a transparent background.

Enhanced Raster Manager preferences

The check box — Use sister file, if present, for georeference — lets worldfiles position rasters containing geocoding in their headers (for example: HMR, ITIFF, Rasters in Intergraph formats, GeoTIFF).

The additional Geotiff Default Units and World File Units are available in the Geotiff settings and World File Units fields.

Enhanced reference support

There exist overrides for the following nested raster attachment settings:

View on/off
Print
Clipping
Transparency

Enhanced monochrome manipulation

New workmodes designed for monochrome rasters issued from Raster References or AutoCAD.

Enhanced display

The display of Intergraph RGB JPEG compressed image file has been improved. This results in a better balance between shadows and highlights.

Enhanced configuration variable

A new configuration variable is added to Raster Manager: MS_RASTER_OPTIONAL_HTTPPORT

This variable allows to add another port. For example, if the variable is set to "MS_RASTER_OPTIONAL_HTTPPORT_8085", Raster Manager will try this port first. If it is not successful, Raster Manager will try the default port.

Reprojection capabilities

Several new Raster Manager features, such as the Coordinate System tab and the On-The-Fly column, exist to support reprojection (on-the-fly transformation) of raster images with MicroStation GeoGraphics 2004 Edition.
