Using the cursor
As a diagnostic aid, a cross-hair cursor can be superimposed over the output image from
the unit.
The cursor can be switched on using the
Enable
button. When enabled, the RGB values for
the pixel at the centre of the cursor are displayed for both the input to the cube and its
output—that is, the pre- and post-transform values are both shown.
Note that these values are 10-bit numbers (reported to 8-bit precision) read
after
any
input scaling and
before
any output video scaling.
By adjusting the
X
and
Y
sliders, any pixel within the active picture area can be selected.
