Set Palette and Remap Options

The Set Palette and Remap dialog box (Figures 6 and 7) offers you several sets of choices:

  • Palette: Use the Palette/Set Palette pop-up menu to choose which existing palette you want applied to the image.

  • Remap Pixels: By default, this box is checked so that pixels in the open image will be remapped to the selected palette's colors. If the open image has 256 or fewer colors (an indexed image), and the box is not checked, you may see some color shifts in the final image. With RGB images this setting has no effect.

  • Dither: Check to simulate additional colors eliminated during the remapping. You can use this option only if Remap Pixels is already checked. In Windows, use the Dithering Options tab if you want to reset your existing dithering level and method. On the Mac, click the - and + buttons to turn on or off and adjust the remap-dither options. For examples, see page C-2 of the color insert in the book.

  • Do NOT use offlimit colors/Do NOT remap to off-limit colors: Check if you want to prevent specific colors from being used in the remapping. Use your cursor to pick off-limit colors in the displayed palette. In Windows, press Ctrl and the mouse to select multiple colors; on the Mac click and drag.

  • Check All/icon All: Use this to put off-limits every color in the displayed palette.

  • Clear All/ Unicon All: Use this to start over if you change your mind about which colors should be put off-limits.
