A Postscript: I'm having the same problem with a horizontal gradient. What looks OK in Fireworks looks horrible in preview. Not only is the gradient lost, but the colors in the screenshot aren't even close to what I used in Fireworks. And the image is almost unrecognizable.
Please see before/after screenshots below.
What version of Fireworks and what optimization settings are you using?
I'm using CS4. My optimization settings are PNG 8, Adaptive. Colors: 4.
I didn't think optimization settings mattered, since I didn't export the image to Dreamweaver. Wrong again?
Yes, wrong again. I just changed to jpeg, and it looks fine.
So, how could I keep that reddish look to the mesh? I've been trying to duplicate it on another file, layering various shades of red below a layer of black mesh with lowered opacity. Is it just trial and error, or is there s simpler way to duplicate my original mistake?
If you're using the Preview in Fireworks, it displays the artwork using the current optimization settings. If it didn't it wouldn't be much of a preview. :-)
Likewise, Preview in Browser will also use the current optimzation settings. PNG is like GIF - it generally sucks at displaying gradients.
JPEG doesn't index color values, so you're likely to be in for some experimentation.
Thank you again, Jim.
