Preview & Dither Operations
---------------------------
Preview
-------
The Preview Operation is designed primarily for users with graphics
cards (esp. Computer Concepts' Colour Card). With one of these cards
fitted you can preview an image in one of the 16 bpp modes.
If you don't have hardware than can display 16 bpp modes then you will
only be able to use this operation to view in 256 colour modes (not of
great use).
In order to use this operation you first need to configure Image so
that it knows what mode to use as the preview mode. You do this via
the Configuration window (see 'Configuration'). For example, with a
Colour Card you could set the mode to 107.
Once the mode has been set, you can preview an image by simply
selecting the preview icon on the Control Panel. Once selected, memory
permitting, the chosen mode is entered and the image displayed at full
size. Holding SELECT allows you to move the image around the screen by
moving the mouse. Pressing ADJUST returns you to the desktop.
Dither
------
The Dither Option will perform a Floyd-Steinburg error distribution
dithering on the current input image, displaying the result in the
display window. This operation can go a long way to make up for the
limited colours available with current hardware. You can dither the
sprite whether it is a 2, 4, 16 or 256 colour sprite. Currently masking
information is ignored during dithering.
The Dither option is very useful as a last thing before saving as a
standard sprite, as it will make the overall picture look much more
like the 24 bit internal picture held by Image.
