Can the whitespace left after suppressing human readable be removed?

Using Code-128 Linear Barcode from JavaBarcode.jar in an ORACLE Report (Version 11.x) on Windows I am creating barcodes for a customer on each detail line, and I want to get as many detail lines per page as possible (there are a lot of lnes on some documents). I have already suppressed the human readable text, and I have also set Top and Left margins to zero as follows:

BarCode.setXDimensionCM(BarcodeObject, 0.03 );
BarCode.setBarHeightCM (BarcodeObject, 0.50 );
BarCode.setShowText (BarcodeObject, false );
BarCode.setLeftMarginCM (BarcodeObject, 0.00 );
BarCode.setTopMarginCM (BarcodeObject, 0.00 );

The resulting barcode, however, still includes the whitespace where the human readable would be. Is it possible to suppress this also?

Thanks in Advance
Hank

In the Java Component, use the property:

setTextMarginCM(double newMargin)

This is the space between the bottom barcode and the human readable (and when no human readable is present). I believe it may be at its default setting and so even without the human readable removed, modifying this property will not make too much of a difference. After removing the human readable and adjusting the margins, the barcode will already be at its smallest size.

Thanks. I added:

BarCode.setTextMarginCM (BarcodeObject, 0.00 );

to the settings for a test and confirmed it is probably already at minimum. The change had no impact on the remaining white space under the bars. From that I conclude that there is no way to get rid of this remaining "margin".

Thanks
Hank
