Inside the Color Options dialog, selecting the User defined option enables the following options:
| | #REDIRECT [[SMS:Color Options]] |
| === User Defined Palettes Frame ===
| |
| * New Palette - Create a new color palette. This opens the [[SMS:New Palette|New Palette dialog]], which is used to define a color ramp palette. The user selects a preset palette and the initial number of colors in the palette. The palette can be fine tuned once it is created in the [[SMS:Color_Ramps|Color Options dialog]].
| |
| * Delete Palette - Delete the selected palette.
| |
| * Load Palettes - Load palettes from an SMS defined [[SMS:Color_Palette_Files_(*.pal)|palette file]].

| The color pallet selected in the '''User Defined Palettes''' frame is displayed. The user can select, edit, and drag colors in the Color Palette using the following tools:
| |
| * Create a breakpoint tool
| |
| ** Mouse left click - Creates new breakpoints
| |
| * Select an individual breakpoint tool
| |
| ** Mouse left click and drag - Changes the value associated with a breakpoint
| |
| ** Mouse left double click - Opens the Color dialog to change the color associated with a breakpoint
| |
| ** Mouse left click, then DELETE key - Delete the selected breakpoint
| |
| | |
| '''Value edit field''' - Change the value of a selected color. Changing a value will move the color inside the color palette window.
| |
| | |
| '''Edit Table''' - This button opens the Color Table dialog. Values and colors associated with each breakline can be viewed and edited. This dialog is useful for creating a palette with a logarithmic scale. It may be difficult to select colors very close to one another at the lower end of a log scale using the mouse left click button, but the values can easily be specified in this dialog.
| |
| | |
| * Display Value As - Show the value of each color as:
| |
| ** '''Percentages (0.0-1.0)''' - A percentage across the palette, with 0.0 being to the left of the palette and 1.0 at the right edge of the palette.
| |
| ** '''Numerical Values''' - The actual value of each color. Each color will represent a value such as elevation.
