Contexts are configured using the Context controls in the lower portion of the Pixel Map tab.
+
Sample X/Y Origin - a pixel location on the source which marks the top-left corner of the context’s rectangular
area.
+
Sample Width/Height - a measurement in screen pixels which specifies the size of the context. (This may be
some or all of the source.)
+
Sub-Sample Width/Height - a measurement in ‘sub-sampling rectangles’ which specifies the sub-sampling
factor. The sub-sampling factor determines which pixels are averaged to create one set of RGB values for output.
(Refer to overview on previous page.)
+
Protocol - the output protocol selection for the context (Art-Net, sACN, KiNET Portout, or KiNET DMXout).
+
Ghosting - a slider to control the transparency level of the context from 0% to 100%.
+
Background Image - allows a background to be added to the context for better visualization of the pixel mapping
configuration. The background can either be a still image or a live stream image. (For instructions on adding a
background, refer to
Note: The bounds of two or more contexts may overlap each other, but need not.
Note: There is no theoretical limit to the number of contexts allowed, but it is best to have no more than 20.
