Seadisp Data Spreadsheet Function: Program-level Documentation

Seadisp Data Spreadsheet Widget

Description: The Data Spreadsheet Widget provides the capability of viewing the raw or geo-physical band data associated with an image display window. The Spreadsheet Widget may be resized in order to view more or less data in the viewable window. The column width and the row height may also be resized by using the Setups button or by dragging the separator bar inside the title fields. The Data Spreadsheet can be opened by selecting either Functions->Spreadsheet->Raw Data or Functions->Spreadsheet->Geo-Physical Data from the Display Window Widget.

Note: For memory and speed reasons, the spreadsheet window only uses a 100x100 buffer. For a data array that has an X or Y dimension greater than 100, the X Start and Y Start slider bar must be used for locating all of the data elements.

Action items:

Window Resize The spreadsheet window may be resized in order to view more or less data in the viewable window.
