Prints the inverse image of graphics page 1.
Normally, awhite dot on the display is reproduced
as ablack dot on the printer paper. This com-
mand will print the background portions of the
display as black on the printer paper, thus repro-
ducing the displayed image as it appears on the
screen. This function is particularly useful for
pictures and portraits.
Rotates graphics image (page 1) 90° in aclock-
wise direction. NOTE: Some printers may require
this function when printing adouble size (zoom)
image (see CTRL-| GD).
Zoom graphics. Prints adouble size graphics
image from the screen. Some printers, such as the
Epson MX-80, FX-80 and Okidata 82A, 92 do not
have enough character positions to print adouble
size image horizontally. Therefore, to print the
double size image properly, the image must be
rotated 90° using the CTRL-| GR command.
Images will be printed in color with color printer.
You can use this function if you have either mono-
chrome (single color) or color display. The colors
of the image are determined by the software
package you are using. When you activate this
command, the software package will send the
color values of each text or graphics character to
the printer. If you wish to change the printed
colors, refer to the software and printer manuals.
THIS FUNCTION IS VERY USEFUL WITH THE
TRANSTAR 315 PRINTER.
Prints an “emphasized” image of the screen.
“Emphasized” means adding more dots to the
characters, creating a more fully-formed, clearer
character. The printer will printtwo closely spaced
dots for every one it would normally print.
NOTE: The Transtar 315 does not support
the “R” or “E” graphics functions when printing
color graphics. .

COMBINING GRAPHICS COMMANDS
OMNIGRAPH allows you the flexibility of combining more than
one graphic function in your graphics command. For example, if
you want to print the inverse of page 2graphics, double size and
rotated 90°, you would enter:
CTRL-I GI2DR (RETURN)
The order in which you enter “I2DR” does not effect the activa-
tion of the function. All functions will be activated. But note: 1) the
CTRL-I G command characters must precede the selected func-
tion characters; 2) the entire command must be activated by
pressing the RETURN key.
PROGRAMMING NOTE: When you are using APPLESOFT
BASIC, you will get aSYNTAX ERROR message when entering
commands from the keyboard. This occurs because BASIC
attempts to interpret these commands as BASIC program state-
ments —which the CTRL commands are not. This occurrence
is merely anuisance and has no effect on the activation or opera-
tion of the selected function. If the SYNTAX ERROR message is
too bothersome, issue commands from PRINT statements as
described in this section.
PASCAL AND CP/M COMPATIBILITY
Your OMNIGRAPH is compatible with both PASCAL and CP/M.
Both require the OMNIGRAPH to be installed in slot #1.
Since the command character, CTRL-I, is used in PASCAL and
CP/M for tabbing, OMNIGRAPH automatically changes the
command character to CTRL-Y (internal to the board) to avoid
any incompatibilities. Use the CTRL-Y command to activate
functions.
Both PASCAL 1.0 and CP/M use the same Input/Output memory
location that OMNIGRAPH uses to activate the right margin
function. To eliminate any incompatibility, the right margin func-
tion is disabled when using PASCAL 1.0 and CP/M. The right
margin function remains active when using PASCAL 1.1.
