Graphics Mode Reassignment
ESC ?
Data Structure
ASCII ESC "?" <s> <n> reassign graphics mode
hex. 1B 3F <s> <n>
dec. 27 63 <s> <n>
Description
This code sequence redefines one of the four alternate bit image codes ESC K, ESC L,
ESC Y or ESC Z as one of the bit density numbers used with the ESC * <m>... code
sequence.
Available values are:
s = 75, 76, 89, 90 (ASCII = K, L, Y, Z)
n = 0 single density
n = 1 double density
n = 2 double density, high speed
n = 3 quadruple density
n = 4 screen graphics
n = 5 plot graphics (1:1)
n = 6 screen graphics II
n = 7 plot graphics, double density
n = 32 single density
n = 33 double density
n = 38 screen graphics II
n = 39 triple density
n = 40 sixfold density
For example, if you send the following code before you run a graphics program, it will
change every instance of mode K (single density) to mode 3 (quadruple density):
LPRINT CHR$(27);"?K";CHR$(3);
