Load Graphics from Band Data Widget

Load Graphics from Band Data Widget

Description: This widget allows the user to create graphics on a display window based on the data ranges or bit masks of pixels from a loaded band image. The bitmap graphics created can be displayed to replace, overlay, or underlay to any graphics on the display window. This widget can be initiated by selecting Functions->Load Graphics->Band Data from the Display Window Widget.

[Command Mode][Interactive Mode]

Interactive Mode:

Input items:

The display window for graphics The display window number for the bitmap graphics created from other image band data to be applied.

Graphics mode

Replace Replace any currently displayed graphics with the new bitmap graphics.

Overlay Overlay the new bitmap graphics on top of any existing graphics (default).

Underlay Underlay the new bitmap graphics beneath any existing graphics but on top of the display image.

The band for generating the graphics The band number in the Band List Selection widget that the image data was loaded to and to be used for creating the bitmap graphics.

Graphics generating option The option of using either the data ranges or bit masks to create the bitmap graphics from the band image data. For the Data range option, the user needs to select the Data type and the Data range to be applied to the band image data. For the Bit mask option, only the bit number to be masked in the band image data is required.

Complement of the selected range/mask The option of using the complement of the data range or bit mask from the band image data. If 'yes' is selected here, the pixels outside the data range selected or the bit mask selected is not on (0), will be assigned as graphics pixels.

Color for band data to generate the graphics The option of graphics colors to be created for each data range or bit mask.

Data type The data type in raw or geophysical units that the values entered in the Data range field will apply to.

Data range The minimum and maximum data ranges (inclusive) to be used for creating the graphics from the specified band image data. All pixels of the band image that have data values (Raw or Geo) between the Min and Max values will be assigned as graphics pixels.

Bit mask The bit number to be checked with all pixels in the specified band image. All pixels with the specified bit number on (1) will be assigned as graphics pixels.

Action items:

Add (Data range) To combine the values in the Data range and the color index in the Color for band data to generate the graphics field as an entry and append it at the end of the List of data ranges/bit masks for graphics window.

Add (Bit mask) To combine the values in the Bit mask and the color index in the Color for band data to generate the graphics field as an entry and append it at the end of the List of data ranges/bit masks for graphics window.

Remove To remove the highlighted data range or bit mask entry from the List of data ranges/bit masks for graphics window.

Clear All To remove all data range or bit mask entries from the List of data ranges/bit masks for graphics window.

Apply Inverse To create the bitmap graphics using the pixels that are not within the data ranges or bit masks selected and listed in the List of data ranges/bit masks for graphics window. The color selected in the first listing will be used as the graphics color.

Apply To create the bitmap graphics based on the specified band image data and the data ranges or bit masks with colors specified in the List of data ranges/bit masks for graphics window and display it on the specified display window.
