Crosshairs, grids and solid colour
The Video Mapper is able to generate and superimpose items over the source video input to assist you during configuration. As well as be-
ing able to apply solid colours to the whole video space, you will find the crosshairs particularly useful when defining the crop area and the
grid invaluable when initially testing the fixture mapping.
Using crosshairs when defining the crop area
When configuring a new installation it
is necessary to define the size and po-
sition of the crop area (within the total
video space) that will form the region
displayed by the PixelArt fixtures.
The Video Mapper provides a set
of crosshairs to assist in locating the
required coordinates of the crop area.
The crosshairs are superimposed on the
video input as seen on the connected
DVI video monitor and also, when they
enter the crop area, on any connected
PixelArt fixtures that are mapped into
the same area.
You have the choice of viewing cross-
hair coordinates relative to the entire
video space origin (absolute) or rela-
tive to the origin of the crop area. The
former is useful when defining the crop
area, the latter is more useful when test-
ing/locating areas once the crop area
has been fully defined.
The current
x
or
y
coordinates (abso-
lute or crop area) of the crosshairs are
shown on the Video Mapper display
and these can be used directly within
the PixelArt Setup Utility.
To use the crosshairs
1 On the Video Mapper, enter the
Pattern Tools menu and select the
‘Crosshair On/Off’ option. Choose
the ‘On’ setting.
Note: You can also change the
colour for the crosshairs.
2 Select the ‘Crosshair Area’ option and choose either ‘Absolute’ or ‘Crop Area 1’ as required.
3 Select the ‘Crosshair X’ or ‘Crosshair Y’ option, as appropriate, and increase or decrease the position value until the crosshair arrives at
the required position, as seen on the monitor and possibly the PixelArt fixtures.
4 Read off the value shown on the display and use this when defining the crop area or locating a section within the crop area.
5 Repeat steps 3 and 4 for the other crosshair.
Using the grid when fixture mapping
The grid feature provided by the Video Mapper is useful when initially mapping
fixtures or when testing fixtures because it can quickly highlight any fixtures that
have been mapped or mounted incorrectly.
To use the grid
1 On the Video Mapper, enter the Video Settings menu and select the Input
Source option. Choose the ‘Pattern Generator’ option.
2 Now enter the Pattern Tools menu and select the ‘Grid On/Off’ option.
Choose the ‘On’ setting.
Note: You can also change the colour for the grid.
3 Select the ‘Grid Pitch’ option and adjust the grid spacing from 0 to 20. If
the PixelArt fixtures are correctly mapped and positioned, you should see a
contiguous grid across all fixtures.
Note: When you have finished with the grid, you need to change the input
source back to either ‘DVI port’ or ‘VGA port’ within the ‘Video Settings’ >
‘Input Source’ menu.
