    Export to jpeg/gif but keep opacity?

    TaylorJumbo
      I'm exporting graphics to be used in a website. All graphics have transparent backgrounds and also they have an opacity of about 60%.

      I have found how to export and keep the transparent background but I can't seem to keep the translucent effect of the lowered opacity (you can't see through the graphics once they're exported).

      How can you export so that the graphics remain semi-transparent?

          The only way to do tat is to export them as 32 bit PNG files, but then
          you have a problem with the images not displaying properly in I.E. 5 & 6
          without a workaround.

          There is another way, but that involves turning the images into a kind
          of mesh you can see through. Let me now if you would be interested in
          the details.

            In addition to what Linda said, here is a workaround for properly
            displaying semitransparent PNGs in IE:

            What as to using pattern mask for creating GIFs, I'll leave it to Linda
            since it was in her book :-)

            What as to JPEG, forget it. JPEG specs do not allow transparency.

              or if the image is ina fixed position you could take some of the
              background from the area you're going to place it over (or sample the
              colour if it's a solid colour) and place it behind the image so some if
              is revelead from below with through the 60% opaque image

              ;)
