Summary of Properties

The properties that can be set to generate an image

AutoCheck     specifies whether any check digits are calculated automatically

BackColor      the colour behind the bars*

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

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

BearerSize      specifies the thickness of bearer bars for those barcodes that may have bearer bars

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

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

CodeType      specifies the barcode type required

Data             specifies the characters that make up the code

ExtendBearers         Allows bearer bars to extend into light margins.

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

FontSize, FontName  specifies the font for human readable text

FontBold, FontItalic   font characteristics for Windows

FontStyle       font characteristics for Java

ImageHeight   required target height of barcode image (in units determined by the setting of Units)

ImageWidth   required target width of barcode image (in units determined by the setting of Units)

Indicators       specifies whether light margin indicators should be displayed alongside human readable text for those barcode types that support these

Justify           specifies the text justification for human readable text under the barcode

MarginSize     specifies the size of the light margins (in units determined by the setting of Units)

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. (Windows only)

Orientation     specifies the orientation of the barcode image

PictureHeight  the height of barcode picture generated (in Pixels) (Windows only)

PictureWidth   the width of barcode picture generated (in Pixels) (Windows only)

BothBearers    determines whether both upper and lower bearer bars are displayed

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

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

Units   specifies the units of ImageHeight, ImageWidth, BorderSize and MarginSize parameters; default is mm (millimeter), also allowed are cm (centimeter) and in (inch)

Xunit            specifies the thickness of each barcode element in Mils (1/1000 inch)

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

CodeType      specifies the barcode type required

Data             specifies the characters that make up the code
