Detailed Description

This view renders a param value as an image (the ParamDisplayView view renders a param value as a string).

The image provided must be a filmstrip with each frame representing each value the param can have.

As a result, this view works for any parameter (both Vst and Jmb) that is (or can be interpreted as) a discrete parameter.

In addition to the attributes exposed by CustomDiscreteControlView, this class exposes the following attributes:

Attribute Description

image

The image to use. The image must be formatted as a filmstrip (similar to the various button views). This means that there should be one frame for each value the parameter can have.

For example for an on/off status LED, the parameter has 1 step (so 2 values) and as a result the image should have 2 frames:

y	frame
0	the frame for off
image height / 2	the frame for on

Example: 2 frames example

inverse Inverses the frames (last frame is first frame, etc...)

Note: This view can be used to render status LEDs for example and all other kinds of graphical representation of a parameter value

See also: CustomDiscreteControlView for details on discrete parameters and the usage of step-count
