Underline text decoration with Liberation Sans too thick

[smfukaya]

Hi,

Flying Saucer 9.7.2 is producing a very thick underline text decoration from an HTML with a "underline" element (<u></u>) using Liberation Sans (it has a underline thickness of 150 — tested with 2.00.5 and 2.1.5 that I built myself).

I compared it to Open HTML to PDF 1.0.10 and found out that it hard codes the underline thickness to 50 in order to produce a more pleasant decoration.

Could you please confirm if the Flying Saucer behavior is expected and if so could you advise me on any workaround.

Best regards,
Sergio

@smfukaya I don't the background of underline sickness, but I see "50" is hardcoded in FS code:

Also, I see that FS can read this number from the font definition (*.ttf files).

Hi @asolntsev ,

Thank you for your quick reply. The problem is that, at runtime, the default thickness value is being overridden by Liberation Sans 150 value for thickness.

FontForge: Liberation Sans 2.00.5

FontForge: Liberation Sans 2.1.5
