#17 BarcodeImageHandler | disable label underline

[Digerati Duke]

Hi,

I am saving Barcode in either PNG or JPEG format but the label of the barcode is having underline. I am rendering those barcode into a table for preview, no underline appears but inside the image file it does.

Does anybody know how disable the label's underline in the output file. I have already tried setup Font into the Barcode.

FYI: And for some reason the GIF format doesn't work (this is not important).

The following is code snippet which is part of my codebase:

[code]
.....
// The BarcodeBean is my bean that encapsulate all the
// barcode related parameters
BarcodeBean barcodeBean= <get instanceof the bean>
// Create the barcode with the text
Barcode barcode = BarcodeFactory.createCode128(barcodeBean.getBarcodeText());
// This doesn't make much difference
barcode.setDrawingQuietSection(false);
// Setup the barcode width (defaulted to 1 pix)
barcode.setBarWidth(barcodeBean.getBarcodeWidth());
// Setup the barcode height (defaulted to 25 pix)
barcode.setBarHeight(barcodeBean.getBarcodeHeight());
// Set the title which not same as the barcode text
barcode.setLabel(barcodeBean.getTitle());
// Save as JPEG
BarcodeImageHandler.saveJPEG(barcode, new File(barcodeBean.getBarcodeImageFile());
.....
[/code]

Thanks
Digerati.

Did you find this bug in Barbecue 1.1? Can you reproduce the bug in Barbecue 1.5 alpha 3?

I found this issue in 1.5 alpha 3 and believe it can be fixed by editing the constructor in CenteredLabelLayout.java and changing the line:

super(x, y, width, NOT_SET);

To

super(x, y, width, BARS_TEXT_VGAP);

I have not done a full impact analysis of this change, I just know that it fixes the problem for my particular needs.

HTH.

Is there any ETA on this fix, as it's blocking us to use this software?

[Kevin]

I use Barbecue 1.5 Beta 1. The problem still exist.
The constructor in file CenteredLabelLayout.java is already updated with super(x, y, width, BARS_TEXT_VGAP);

Any solution?

One solution: Change SizingOutput.java drawText() to:

public int drawText(String text, LabelLayout labelLayout) throws OutputException {
        if(font == null || fm == null) {
            return 0;
        }
        GlyphVector gv = fm.getFont().layoutGlyphVector(fm.getFontRenderContext(), text.toCharArray(), 0, text.length(), Font.LAYOUT_LEFT_TO_RIGHT);
        Rectangle2D r2d = gv.getVisualBounds();
        return (int)r2d.getHeight() + CenteredLabelLayout.BARS_TEXT_VGAP + 1;
    }
