LUT-Operator  Example 

This operator applies a LookUpTable to an image.
Unlike to all other image-processors LUT's are represented
by Envelopes and can be morphed !
There are 6 Envelopes: a Start- and an End-Envelope for every
component. After specifying the number of frames the Start-Envelope
is morphed into the End-Envelope. Different point-counts
are possible.

Parameters

Name        Possible Values/Unit            Description

Input       STREAM, TEMP1, ..., TEMP8       input buffer
Ouput       STREAM, TEMP1, ..., TEMP8       output buffer
Mode        EDIT, VIEW                      toggle Edit/View-mode
Type        LINEAR, SPLINE, BEZIER          type of the spline of the current channel
Component   R, G, B                         current component
RGB         (gadget)                        apply the current Envelope to all components
Preset      (may change)                    choose a preset
Apply       (gadget)                        apply the selected preset to the current component
Position    START, END                      modify the Start- or the End-Envelope
Both        (gadget)                        apply the Envelope of the current component as
                                            End- and as Start-Envelope
Frames      integer>0                       number of frames used for morphing
Frame       integer>0                       current frame displayed in view-mode
MirrorX     (gadget)                        mirror the current Envelope along the x-axis
MirrorY     (gadget)                        mirror the current Envelope along the y-axis
MirrorXY    (gadget)                        flip the current Envelope along the diagonal
MoveX       (gadget)                        shift the current Envelope by the specified amount in x-direction
MoveY       (gadget)                        shift the current Envelope by the specified amount in y-direction
Amount      integer                         shift-value
File        string                          file used for loading/saving envelopes
Load        (gadget)                        load an Envelope
Save        (gadget)                        save the current Envelope to disk

There are two modes: the View- and the Edit-mode. In Edit-mode
all changes are applied, in view mode the morphing of the
splines is visualized. In this mode you can change the current-frame-
number both using the scrollbar and the "Frame"-gadget.


If you want to create your Envelopes using the Envelope-Window
the only restriction is that all values must be in the range 0..255.
The first point must have the x-coordinate 0, the last one the
coordinate 255.
