Summary of Properties

 

The most important properties are outlined below, and followed by sections in which the properties are defined in detail.

The properties that can be set to generate an image

M_barcode.AutoParity         specifies whether any check digits are calculated automatically

M_barcode.BackColor          the colour behind the bars

M_barcode.BarRatio  specifies the ratio of wide/narrow bar (times ten) for some barcode types

M_barcode.BarReduce         specifies the percentage reduction in bar thickness (useful for allowing for ink spread in wet-ink printing processes.

M_barcode.BearerBarThickness  specifies the thickness of bearer bars for those barcodes that may have bearer bars

M_barcode.BorderSize         specifies the thickness of any border around the image (in points)

M_barcode.Caption    specifies the characters that make up the code

M_barcode.CharSpacing       the percentage of the barcode width over which the text under the barcode should be spread out.

M_barcode.CodeType specifies the barcode type required

M_barcode.ExtendBearers    Allows bearer bars to extend into light margins.

M_barcode.ForeColor the colour of the bars and any text under the bars

M_barcode.FontSize, FontName, FontBold, FontItalic are alternative ways of specifying font characteristics

M_barcode.ImageHeight      required target height of barcode image (in units determined by the setting of ScaleMode)

M_barcode.ImageWidth       required target width of barcode image (in units determined by the setting of ScaleMode)

M_barcode.JustifyText         specifies the text justification for human readable text under the barcode

M_barcode.MarginSize         specifies the size of the light margins

M_barcode.NominalSize       specifies a percentage of the barcode's standard size at which the image should be created. If specified the calculated value overrides the ImageHeight and ImageWidth parameters.

M_barcode.Orientation         specifies the orientation of the barcode image

M_barcode.PictureHeight      the height of barcode picture generated (in Pixels)

M_barcode.PictureWidth       the width of barcode picture generated (in Pixel)

M_barcode.ScaleMode         specifies the units of ImageHeight and ImageWidth and PictureHeight and PictureWidth parameters (default is 0 = HIMETRIC = 0.01 mm)

M_barcode.ShowBearerBars  determines whether (or how many) bearer bars are displayed

M_barcode.ShowText specifies that the text content of the barcode should be displayed under the bars

Axbarcode.ShowCheckDigit  specifies whether any automatic check digit is displayed (for those barcode type which permit this)

M_barcode.ShowLightMargin  specifies whether light margin indicators should be displayed for those barcode types that support these

M_barcode.xunit                specifies the thickness of each barcode element in mils

 

Many of these properties have default values (see the reference section), so do not require changing if you can make do with the default values. The properties that must be set for you to obtain a barcode are

M_barcode.CodeType specifies the barcode type required

M_barcode.Caption    specifies the characters that make up the code

A typical example of setting these properties is:

M_barcode.CodeType=8     rem code type is 8 for Code-39 type barcode

M_barcode.Caption="123456"     rem code is 123456
