Controlling the Grid Size (Grid Centred)

Setup menu Force centre
Mode menu Centre
Size When the grid is centred, the left shaft encoder is used to adjust the height and the right shaft
encoder is used to adjust the width of the grid about the centre of the raster.

Controlling the Grid Size and Position (Grid not centred)

Setup menu Force centre
Mode menu Centre
When the grid centering is Off the H and V lines can be positioned independently in one of four modes.
V track The left shaft encoder is used to adjust the vertical position of the grid, i.e. move the grid up or
down and the right shaft encoder is used to adjust the height of the grid.
V no track The left shaft encoder is used to adjust the top of the grid and the right shaft encoder is used to
adjust the bottom of the grid.
H track The left shaft encoder is used to adjust the horizontal position of the grid, i.e. move the grid left
or right and the right shaft encoder is used to adjust the width of the grid.
H no track The left shaft encoder is used to adjust the left side of the grid and the right shaft encoder is
used to adjust the right side of the grid.

CONTROLLING THE MASK OBJECT

The mask object consists of a horizontal masked area at the top and bottom of the raster, and a vertical
masked area at the left and right side of the raster. Throughout the remainder of section 3.4.3.3 the mask
dimensions refer to the boundaries between the masked and unmasked area as shown in Figure 3-5. The
left side of the mask is the first unmasked pixel, the right side is the last unmasked pixel. The top of the
mask is the first unmasked line and the bottom of the mask is the last unmasked line. The horizontal
transitions from mask to image are shaped as shown in Figure 3-5. The vertical transitions from mask to
image are hard transitions.
