How to add font with specific character set in openspades?

[noway]

So, like japanese with font-mplus-ja.pak. Russian font looks terrible currently, so i want to add normal font package for it.

Or maybe you can specify fallback font?

Sources/Tools/BdfToOSFont.cpp

[noway]

Thanks for the tool! It's not working for me, though.
It's generating this output http://pastebin.com/QNBdkidR and 1x1 .tga image.

This is my bdf font: https://gist.github.com/noway421/a5b914e32eb95a32e274

What i am doing wrong?

[yvt]

Sorry but currently BdfToOSFont is designed to handle only certain BDF files due to its complexity (and complete lack of my knowledge about BDF format), so source code modification is required for almost every font to be converted.

You might be able to get it working easily if you could create something called "Unicode BDF".

[noway]

This BDF font is in unicode already.

I tried to generate font with '(Unicode, Full)' but its not working too.

sed -e "s/STARTCHAR /STARTCHAR U+/g" < in.bdf > processed.bdf

[noway]

It works! But in result file all characters vertically flipped. How to fix it?

[yvt]

No problem, it should works.

Looks like BbfToOSFont doesn't understand BBX field correctly.

STARTCHAR U+0434
ENCODING 1076
SWIDTH 500 0
DWIDTH 8 0
BBX 8 16 0 -2
BITMAP

STARTCHAR U+0434
ENCODING 1076
SWIDTH 500 0
DWIDTH 8 0
BBX 7 9 1 -1
BITMAP
3C
24

FE
82
ENDCHAR

This is character ('д' in that example) declared in two different ways. In first it altered with empty pixels, in second BBX field is modified.
In second case BBX field processed not correctly by BbfToOSFont. Character becames incorrectly positioned.

Can you fix it? This two examples should give same result.

To clear things out: this output produced by fontforge - popular font editor.
So it would be neat if this software would be supported.

[yvt]

Fallback font’s format was updated to support negative offset, and BdfToOSFont now supports BBX directive

[noway]

Ehm, looks like it's not working. I compiled new BdfToOSFont and openspades from git, but results are same.
How it should be (generated from hand-written file):

How it is (generated from font, that was rendered in fontforge):

[noway]

Also, hand-written font looks better after your fix (it is better aligned then before). So there is some progress.

BBX is now correctly processed

font-unifont.pak:

Now it works with fontforge fonts! Thanks!
