FAX or T4
PRINTER or TEXT
PCL
POSTSCRIPT and PS are synonyms. FAX and T4 are also synonyms, as are PRINTER and TEXT. Printer
format is the normal default for ASCII files. PCL (Printer Control Language) is valid only for the output file,
while PostScript format is only valid for the input file.
The /LEFT _MARGIN qualifier specifies the amount of white space between the left edge o f th e do cumen t
and the bitmapped image. This is measured in dots, or as specified by the /UNIT qualifier. If a negative left
margin is specif ied , th e image will b e sh if ted lef t ins te ad of righ t an d th e im age is cr opped. Decimal fractions
are allowed.
The / NO TI FY qualifier spe cifies that a broadca st message will b e sent to the user terminal wh en the
conversion completes.
The /PAGE qualifier specifies the height (length) of the output image, which is measured in dots, or as
specified by the / UN IT qualifier. T his value must b e greater than zero. As an examp le, you can use th is
qualifier to reduce the height of a scanned-in logo file to a few inches instead of the whole page.
The /PRINT qualifier, if used, causes the output file to printed. The printer should be set up with / SCALE
to ensure the printed image is dimensioned correctly. (See the PRINTER command description above.)
The /T OP_MARGIN qualifier specifies the amount of white space between the top edge of t he docu ment
and the bitmapped image. This is measured in dots, or as specified by the /UNIT qualifier. If a negative top
margin is sp ecified, th e image will be sh ifted up in stead o f down and t he image is cropped. Decimal fractions
are allowed.
The /UNI T qualifier specifies the unit of measure for left margin, top margin and page height. Valid units
are:
/ UNIT= DOTS
/UNIT=INCHES
/UNIT=MM
/ UN I T= MILLIME TE RS
/ UNIT= POINTS
MM and MILLIMETERS are equivalent. There are 25.4 millimeters to an in ch an d 72 po in ts to an in ch . F ax
resolutio n is 204 dots per inch h orizont ally and 196 dot s per inch vertically. If t he / U NI T qu alifier is
omitted, the unit default value is dots.
5.5.1.2 Examples
Here are some co n ver sio n examples:
$ FAX CON VE RT N EWLOGO.P S / PAGE= 2.5 / U NI T=I NCH / PRI NT
$ FAX CONVERT IN.X / FORMAT=TEXT OUT.Y /F ORMAT=PCL
$ FAX CON VERT T EST.T 4 / LEF T= 72 / TOP= -36 / U NI T=P OIN TS / P RIN T
The first example creates a bitmapped T4 output file, called NEWLOGO.T4, from PostScript input file,
NEWLOGO.PS, with a height of two and a half inches and prints it. The second example converts text file
IN.X into a PCL file, OUT.Y, which may later be printed on a PCL type printer (using the DCL PRINT
command.) N ote that the / FO RMAT= TE XT qualifier was n ot necessary in this case, since th e pro gram
would have defaulted the input file to text anyway. Since the printer uses PCL format, another method of
obtaining a PCL format is to use the CONVERT command with the /PRINT qualifier and then copy the
print file wh ile it is being p rinted.
