TTF and OTF versions of Source Sans Pro are differently displayed in Swing (Nimbus L&F)

Question

ttf:

otf:

both are the same font but different fontfile types

I am running Java 7 in Windows 7

According to Miguel Sousa by Adobe the bug is not in the fonts https://github.com/adobe/source-sans-pro/issues/32#issuecomment-23319673

I am just setting the default font to the new font. The TTF version works without any issues

Font font_o = Font.createFont(Font.TRUETYPE_FONT, fonts.class.getResourceAsStream("fonts/TTF/SourceSansPro-Regular.ttf"));
//Font font_o = Font.createFont(Font.TRUETYPE_FONT, fonts.class.getResourceAsStream("fonts/OTF/SourceSansPro-Regular.otf"));
Font font_n=font_o.deriveFont(Font.PLAIN, UIManager.getLookAndFeelDefaults().getFont("defaultFont").getSize());
UIManager.getLookAndFeelDefaults().put("defaultFont",font_n);

Why is there a difference in the lineheight?

• not true that Java, nor Nimbus bug, this bug in Font, you can to see that in Metal, Win, WinClassic and Nimbus Laf, OTF_Font missing 2pixels above glyph

. Windows .

. Metal .

. Nimbus .

WinXp on Java6

• this code will help you to find difference(ies) between two fonts (and to report all diff's to author)

• returns all available atributes from (java.awt.font.)TextAttribute for concrete Font

• you can to get detailed properties from (almost) all TextAttributes

with output

java.awt.font.TextAttribute(family)
java.awt.font.TextAttribute(weight)
java.awt.font.TextAttribute(width)
java.awt.font.TextAttribute(posture)
java.awt.font.TextAttribute(size)
java.awt.font.TextAttribute(transform)
java.awt.font.TextAttribute(superscript)
java.awt.font.TextAttribute(char_replacement)
java.awt.font.TextAttribute(foreground)
java.awt.font.TextAttribute(background)
java.awt.font.TextAttribute(underline)
java.awt.font.TextAttribute(strikethrough)
java.awt.font.TextAttribute(run_direction)
java.awt.font.TextAttribute(bidi_embedding)
java.awt.font.TextAttribute(justification)
java.awt.font.TextAttribute(input method highlight)
java.awt.font.TextAttribute(input method underline)
java.awt.font.TextAttribute(swap_colors)
java.awt.font.TextAttribute(numeric_shaping)
