RENDER ON/OFF
Intermec Fingerprint v8.70.0/v10.0.0 Programmer´s Reference Manual
Chapter —Program Instructions
Purpose Statement for enabling/disabling rendering of text, bar code, image, box,
and line fields.
Syntax RENDER ON|OFF
ON enables rendering (default).
OFF disables rendering.
Remarks These statements are intended to get information regarding size and
position of a field without actually rendering it, that is the field will not
be printed when the program is executed. The information on the field is
retrieved using PRSTAT functions.
RENDER OFF disables the rendering, which means that PRTXT,
PRBAR, PRIMAGE, PRLINE, and PRBOX statements will not give any
result when a PRINTFEED statement is executed. Any other statements
than PRPOS will not update the insertion point. Field numbers (see
FIELDNO) will not be updated. Statement such as CLIP ON/OFF, XOR-
MODE ON/OFF, or BARSET will retain their usual meanings. PRBUF
will render a field regardless of RENDER ON/OFF.
RENDER ON enables field rendering after a RENDER OFF statement.
Duplicate statement have no effect, that is if a RENDER OFF statement
has been executed, another RENDER OFF statement will be ignored. The
same applies to RENDER ON.
Example This examples retrieves information on the size of a text field which was
not rendered. (The actual result may vary depending on font, font size,
and printer type.)
