Converted and unsupported Photoshop features in Fireworks
When you open or import a Photoshop file, Fireworks converts
the image to PNG format using import preferences that you specify.
(See Photoshop Import preferences.)
Individual layer masks convert to Fireworks object masks.
Group masks are unsupported.
Clipping masks convert to object masks, but their appearance
changes slightly. To maintain appearance but lose editability, select
the Clipping Masks preference.
Blending modes for layers convert to blending modes for Fireworks
objects, if corresponding modes exist.
Layer effects are retained by default. If you prefer to convert
these effects to corresponding Live Filters, select the Layer Effects
preference. Note, however, that similar effects and filters might
differ slightly in appearance.
The first alpha channel in the Channels palette converts
to transparent areas in the Fireworks image. Fireworks does not
support additional Photoshop alpha channels.
All Photoshop color depths and modes convert to 8-bit RGB.
Adjustment layers are unsupported.
