Detaching Raster Files
You can detach one, multiple, or all raster references.
Use the following key-in to prevent rasters from being deleted when they are included in a selection set:
If mirroring, warping, resizing, or clipping modifications were brought to the image, detaching the image will result in the loss of those settings. For more information, see Moving, Warping and Resizing Image Files.
When detaching a read-write mode raster file, if the native information of the file has been modified during the work session, Raster Manager automatically saves the changes made to the raster file. This applies to the following "native" information:
- Georeference which is native to the file (geotiff/HMR/Intergraph formats, and others)
- Georeference stored in a sister file
- Coordinate systems and projections in a geotiff.
If the file being detached does not have native georeference or georeference stored in an already existing file, the Save Location Information check box in the Preferences dialog has to be selected for the file to be updated. Otherwise, if the file has native georeference or if it already has a sister file, it will be updated regardless of the check box setting.
Automatic file saving controls the detach operations in Raster Manager. By default, automatic file saving of rasters is activated, meaning the user is not prompted when changes to the files are committed in a detach operation. You can change the default behavior for automatic file saving so that each detach operation in Raster Manager will prompt for saving or not saving the image, whichever case applies.
Use the following key-ins to change the default behavior of automatic file saving:
- RASTER SAVEAUTO SETON to activate automatic file saving
- RASTER SAVEAUTO SETOff to disable automatic file saving
- RASTER SAVEAUTO TOGGLE to invert automatic saving status
- RASTER SAVEAUTO GET to get the status of automatic saving (in the status field).
You can also use the following configuration variables:
- MS_RASTER_SAVEAUTO = 0 to disable automatic file saving.
- MS_RASTER_SAVEAUTO = 1 to activate automatic file saving.
In order to activate the MS_RASTER_SAVEAUTO = 0 configuration variable, the product needs to be exited and reopened.
