Instruction to Color Table Dialog Box

Toolbar Description

  • Click the Add icon to open the default color board. The selected color will be added as the last record in the list box.
  • Click the Batch Add icon to open the Batch Add dialog box.

    • Start Value: The start value of the batch adding cells.
    • End Value: The end value of the batch adding cells.
    • Increment: The cell value gradually increases by the increment from the start value to the end value.
    • Step Count: The added step count. End Value - Start Value / Step Count = Increment.

Either Increment or Step Count can be active, which means they can be used at the same time.

  • Auto calculate the end value: This parameter must be used together with Increment. If the specified end value cannot make the result of the formula “End Value - Start Value / Step Count” is an integer, then the end value needs to be rectified. For example, the start value is 150, the end value is 1002, the increment is 100, if the check box is selected, the end value in the color table is 950, not 1002.
