| | #REDIRECT [[SMS:New Palette]] |
| === 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]].

| === Current Palette Frame ===
| |
| 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.
