Color Table

The "Color Table" button is used to set the color table for raster data participating in 3D orthophoto generation. The generated 3D orthophoto will display this color table.

Color Table Dialog Description

Toolbar Description

  • Click the "Add" button to open default color palettes. Selected colors will be appended to the end of the color table list.
  • Click the "Batch Add" button to open the "Batch Add" dialog:
    • Start Value: The initial pixel value for batch addition.
    • End Value: The terminal pixel value for batch addition.
    • Step: Specifies the increment between consecutive pixel values from the start value to the end value.
    • Number of Levels: Determines the step size by calculating (End Value - Start Value)/Number of Levels.

    Note: Only one parameter (Step or Number of Levels) can be set at a time.

  • Auto calculate the end value: Works with Step parameter. Automatically adjusts end value when manual input causes non-integer division results. Example: If start=150, end=1002, step=100, the auto-adjusted end becomes 950.
  • Click the "Insert" button to insert selected colors before the currently selected record in the list.
  • Click "Select All" to highlight all records in the list.
  • Click "Invert Selection" to toggle selection states of list records.
  • Click "Delete" to remove selected records from the list.
  • Click the dropdown arrow next to "Color Scheme" button to choose a color scheme. Note: When multiple records are selected, only applies to chosen entries.
  • Click "Restore" to reset color schemes. Note: When multiple records are selected, only resets chosen entries.
  • Click "Reverse" to invert color sequence of color schemes. Note: When multiple records are selected, only reverses chosen entries.
  • Click "Import Color Table" to load external color tables. For details see Import/Export Color Table.
  • Click "Export Color Table" to save current color table. For details see Import/Export Color Table.

List Box Description

The list box displays elevation values with corresponding colors and serial numbers.

  • Serial numbers are automatically generated and cannot be modified.
  • Clicking a color cell opens a color picker for editing.
  • Modify elevation values directly in the "Value" column text boxes.
