Syntax 
object.Wide2NarrowRatio [ = fWide2NarrowRatio ]
Possible Values
fWide2NarrowRatio Double that specifies or receives the Wide2NarrowRatio property

The property is read/write.



NonPrintingToTxt Property
Returns or sets the value indicating whether nonprintable chars should be converted into their text representation.
For instance, if a barcode has the hexadecimal char 00h in it, in the human readable text this character will be replaced with "NULL", 0Dh will be replaced with "CR", etc.
If this property is set to False and there are nonprintable chars, such chars will be just skipped.
This property makes sense only for barcodes that can encode the full ASCII char set, e.g. Code 39 Extended or Code 93 Extended.
For example:

BarText = "Hello ~0Dworld"
BarType = Code93Ext
NonPrintingToTxt = True
Human readable text will be - "Hello <CR>world"

if NonPrintingToTxt = False then Human readable text will be - "Hello world"

Possible Values
sImgFormat String that specifies or receives the ImgFormat property: 'gif', 'jpeg', etc

The property is read/write.



JPEGQuality Property
Returns or sets the value indicating the image quality in the JPEG format.
This property makes sense only if the SaveToImageFile method is used and the barcode is saved to a JPEG file.

Syntax 
object.JPEGQuality [ = lJPEGQuality ]
Possible Values
lJPEGQuality Integer that specifies or receives the JPEGQuality property
The value of this property must be within the range of 0..100, where 100 is the highest quality.

The property is read/write.



IsBarTextOk Property
Returns the value indicating whether the BarText property is set correctly.

Syntax 
object.IsBarTextOk
Possible Values
bIsBarTextOk Boolean that receives the IsBarTextOk property

The property is read only.



MinBarcodeWidth Property
Returns the value indicating the smallest possible barcode width with its current properties. This value is always returned in pixels.
Mind that this property does not depend on the barcode оrientation and determines the barcode width perpendicular to the bars.

For example:
Barcode minimal width

Syntax 
object.MinBarcodeWidth
Possible Values
lMinBarcodeWidth Integer that receives the MinBarcodeWidth property

The property is read only.
Remarks
Be careful because this method returns exactly the smallest possible barcode width in pixels, i.e. the narrowest bar will have the width of 1 pixel. If you print a barcode with such width on a high-resolution printer, a scanner may fail to read it.
That is why you\92d better use the GetBarcodeWidth method to determine the barcode width.



BarWidthReduction Property
Returns or sets a percentage value for the reduction or gain of the width of the bars in a BarCode .NET control.

Syntax 
object.BarWidthReduction [ = lBarWidthReduction ]
Possible Values
lBarWidthReduction A Integer value specifying either a positive or a negative percentage to reduce or increase the width of all bars in a bar code.
The value for number may range between 99 (reduction) and -99 (gain).

The property is read/write.
Remarks
The BarWidthReduction property allows you to set a Reduction or Gain factor ranging from 99 (% reduction) to -99 (% gain). The default value for the BarWidthReduction parameter is zero. Specifying a non-zero value for the BarWidthReduction parameter causes the BarCode .NET control to reduce or enlarge the width of all solid bars in a bar code. Bar Width Reduction is often necessary to compensate for ink spread when generating bar codes that will be used in wet ink printing processes (i.e. printing presses).
The percentage that you specify is based on the narrow bar width (x-dimension) that you choose for your bar codes. For example if you specify a BarWidthReduction value of 25 and your narrow bar width (x-dimension) is set at 10 mils, the width of all bars in your bar codes will be reduced by 2.5 mils (25% of 10 mils = 2.5 mils). Bar width gain is typically used when printing on glass or other surfaces that cause ink to bead up or shrink as it dries. To specify bar width gain instead of reduction, use a negative percentage value. An error event is generated if you specify a BarWidthReduction value greater than 99 or less than -99.

The amount of BarWidthReduction to use depends on a number of factors including the type of paper that the bar codes will be printed on, the type of ink that is being used and the speed and plate pressure of the printing press. Typical values for this property range from 5 to 25 percent however it is recommended that you consult with your printer about the best value to choose.
