PCX GRAPHICS EXAMPLE
A graphics file in a PCX format may also be transmitted to the printer. The file must
not be larger than 32K bytes (DOS file size reported in a DIR listing). For example,
the WIZ.PCX image shown below has a file size of 15076 bytes.
The uncompressed size (PCX is a compressed file) of the file must not be greater than
64K bytes. Generally this is not a problem unless the graphic image is surrounded by
large amount of white space which the PCX algorithm can compress very efficiently.
If this is the case, the file should be recaptured to eliminate the surrounding white
space as much as possible.
The following basic program will send and print this file:
OPEN “WIZ.PCX” FOR INPUT AS #2
DA$ = INPUT$(15706, #2)
C$ = CHR$(27)
WIDTH “LPT1:”, 255
LPRINT C$; “A”;
LPRINT C$; “V150"; C$; ”H100"; C$; “GP15706,”; DA$
LPRINT C$; “Q1"; C$; ”Z";
CLOSE #2
The printer output for this program is:
