Using grayscale
Texas
Intsruments'® Calculators are not made to display
grayscale graphics. But ETP-Basic contains a library
that allows the calculator to display them.
First, you must set the grayscale mode on. So simple
:
This command allows the calculator to go in grayscale
mode. After, you must act as if there were to planes
: a dark one and a light one.
To choose the dark plane :
... And the light one :
You can now use classic functions to display things.
Example :
GrayOn
DarkPlane
Locate 1,10,"It's Dark !",4
Locate 1,20,"It's also Dark !",4
LightPlane
Locate 20,40,"This is Light !",4
Locate 20,50,"So it is !",4
|
And so on, everything written after DarkPlane
to LightPlane
will be on the dark plane, and dark on the screen.
| Important Note : For
the PutTile
function, you don't need to change the plane,
it is autpomatically done. But you have to
activate grayscale mode,
with the instruction GrayOn,
otherwise it will be in black and white. |
Before quitting your program, the calculator must
be set back in normal mode. So you must stop grayscales
by typing :
And the black ?
To have a black element, you must activate pixels
in both planes, like that :
DarkPlane
Locate 1,10,"This is black",4
LightPlane
Locate 1,10,"This is black",4
