- symbology (Integer, optional): type of the barcode, default is Code 128 if not passed
- option1 (Integer, optional): option 1 (see demo database for possible values)
- option2 (Integer, optional): option 2 (see demo database for possible values)

- showtext (Boolean, optional): shows a human readable text below the barcode, if supported
- mode (Integer, optional): decode mode (default is hmBC_Input_Data Mode if not passed), you can use the following constants:
- hmBC_Input_Data Mode
- hmBC_Input_Unicode Mode
- hmBC_Input_GS1 Mode
- hmBC_Input_Escape Mode
- primary (Text, optional): additional text, depends of the barcode, see demo database.
- output (Text, optional, default = “svg”):
- “svg”: Status object returns a SVG picture
- “matrix”: Status object returns matrix-text with 0, 1 and comma drawing information
Status returns an object with the result or possible errors:
- picture (Picture): SVG-picture of the barcode or Null if an error occurs. output must be “svg”
- matrix (Text): drawing information of the barcode: 0 (white), 1 (black) and comma (next line). output must be “matrix”

Example
The following example creates a QR Code picture and saves it to disk:
var $vo_status; $vo_barcode : Object
$vo_barcode:=New object
$vo_barcode.text:="this is a demo text"
$vo_barcode.symbology:=hmBC_QR Code
$vo_status:=hmBC_Generate Barcode($vo_barcode)
If ($vo_status.success)
WRITE PICTURE FILE("test.svg"; $vo_status.picture)
End if
Result:
The following example creates a GS1-128 Barcode:
var $vo_status; $vo_barcode : Object
$vo_barcode:=New object
$vo_barcode.showtext:=True
$vo_barcode.mode:=hmBC_Input_GS1 Mode
$vo_barcode.text:="[01]98898765432106[3202]012345[15]991231"
$vo_barcode.symbology:=hmBC_GS1 128
$vo_status:=hmBC_Generate Barcode($vo_barcode)
If ($vo_status.success)
WRITE PICTURE FILE("test.svg"; $vo_status.picture)
End if
Result:
