00062: How to determine the CPI and POINT size of the SYSPRINTer’s font

Title:

How to determine the CPI and POINT size of the SYSPRINTer’s font

Description:

To determine what the CPI and POINT Size of the current FONT, you can do the following: 

f_1$=fin(chan,ind=1) 

cpi=f_1.xppi/f_1.char_width 
points=72.2*f_1.char_height/f_1.yppi) 

This can then be plugged into a ‘font’ mnemonic as: 

print (chan)’font'(f_1.font$,cpi,points) 

This example starts with a FONT=,ROWS=,COLS= on the OPEN mode. Assume that in a report you need to print a large piece of text to emphasize something, but then you want to go back to the original size text. 

0010 LET CHAN=UNT 
0020 OPEN (CHAN,MODE=”FONT=Courier,ROWS=66,COLS=80″)”LP” 
0030 DIM F_1$:TMPL(CHAN,IND=1); LET F_1$=FIN(CHAN,IND=1) 
0040 LET CPI=F_1.XPPI/F_1.CHAR_WIDTH 
0050 LET POINTS=72.2*F_1.CHAR_HEIGHT/F_1.YPPI 
0060 PRINT (CHAN)”All kinds of neat data” 
0070 PRINT (CHAN)’FONT'(“Letter Gothic”,5,20),”This should be large” 
0080 PRINT (CHAN)’FONT'(F_1.FONT$,CPI,POINTS),”Back to regular size and font.” 
0090 PRINT (CHAN)’FF’,; CLOSE (CHAN)
