Every time that you create a job by adding an image or mosaic to GeoExpress, the job uses a set of default options from the preferences. Set your preferences to change these default options. To access the preferences for you jobs, click Options > Preferences in the menu bar. Preferences pertaining to most job types are in the General and Appearance tabs of the Preferences dialog box. Preferences for raster jobs can be accessed through the MrSID and JPEG 2000 tabs. Set preferences for LiDAR jobs in the LiDAR tab.
