5•On the RTC
®
5, only one pixel mode is available (equivalent to the RTC
®
4’s
PixelMode
=1) .
•The RTC
®
5 allows selection of the output channel (
Channel
) for analog signals (in pixel
output mode, the RTC
®
4 can only output analog voltage levels at its ANALOG OUT2
port).
•For the RTC
®
5, the pixel output period is specified as the half output period
HalfPeriod
(in contrast, for the RTC
®
4 it is the full output period
PixelPeriod
).
• For the RTC
®
5, the command set_pixel_line requires only one list entry, as with other
normal list commands (whereas the RTC
®
4 requires two list entries).
•In RTC
®
4 compatibility mode,
HalfPeriod
must be specified in units of 1/8 µs. The para-
meter values will then be internally converted to 1/64 µs units (i.e. multiplied by 8). The
permissible range of values is correspondingly smaller (the smallest permissible value is
then 13). In RTC
®
4 compatibility mode, the RTC
®
5 also multiplies the specified coordi-
nate values
dX,dY
by 16 (the permissible range of values is correspondingly reduced).

Command
set_pixel_line_3d
Function activates the pixel output mode and defines various pixel output parameters
.
Call
set_pixel_line_3d( Channel, HalfPeriod, dX, dY, dZ )
Parameters
Channel
See set_pixel_line (number of the analog output port).
HalfPeriod
See set_pixel_line (half pixel output period).
dX, dY
See set_pixel_line:
Distance in the X and Y directions between adjacent pixels in bits
(64-bit IEEE floating point values)
dZ
Distance in the Z direction between adjacent pixels in bits
(64-bit IEEE floating point values)
As with all Z-coordinates,
dZ
too is scaled 16x smaller than
dX
and
dY
.
Comments • Unlike set_pixel_line, set_pixel_line_3d lets you define the pixel spacing (between two
adjacent image points on a line) via a 3D vector.
•Unlike set_pixel_line, set_pixel_line_3d will additionally require two list-memory loca-
tions if parameter
dZ
is non-zero. The initial component executes as a short list
command before the primary component (a normal list command). Any still-pending
delayed short list command will get executed first.
• In other respects, set_pixel_line_3d behaves similarly to set_pixel_line (see the
comments there).
