Prototype

intWidth:=ImgDrawBarcode(intImageHandle,intX, intY, intHeight, intModulus, strData)

Description

Draw a Code39 standard barcode in specified position encoding passed data.

Parameters

intImageHandle: integer value corresponding to the image handle.

intX: integer value, the pixel position from left side where to place the barcode

intY: integer value, the pixel position from top side where to place the barcode

intHeight: integer value, the height of barcode in pixels (the width is auto-calculated according to data content)

intModulus: integer value, the barcode modulus, the width in pixel of small bars.

strData: string value, the data to be codified in the barcode.

Returned value

Integer value, the barcode width in pixels including bars and quite right and left space.

Notes
