    Palette for JPG export

    Fireworks_forever
      Hi!

      When I export BMPs with the "Layers to files" command, I can control the number of colors by creating a palette.
      Can I do the same thing when exporting JPGs "Layers to files"?

      I have not found a way to do this in Fireworks and the work-around conversion program I use changes the ppi of the image so it is useless.

      I need JPGs because it is the only format my hardware device (simulation platform) can read and I need it in 256 colors to simulate what it will look like on the final product. Please help me!

      Great forum by the way!

      Kind regards

          No. JPG compression shifts color by it's nature so you can't specific a
          specific palet.

          JPGs don't support a limited 256 color palet.

            As it was already pointed out, JPEG does not have a "palette", JPEG is
            continuous type image. Among image types FW is likely to output, GIF or
            PNG may have 256 colors, and "indexed color" (aka "palette") type.

              export it as a gif and choose your palette there, then open the gif and
              export as a jpeg at 100% ?

                That might 'emulate' the situation but certainly won't give you a JPG with a
                specific palet.
