However, some of the options may reduce the font quality. In the top menu, select File->Generate Fonts, then Options and make sure that PS Glyph Names is unchecked:įollowing the three steps above, we reduce the file size of simhei.ttf from 9.57MB to 1.98MB.įurther minor size reduction should be possible by using Elements->Font Info. ![]() The final step is to remove the Glyphs names which takes a lot of space and are of no use for embedded systems. Then on the top menu click on CID->Flatten to return to normal font type. Select Delete to remove the extraneous glyphs. In the top menu in Fontforge, select CID->Convert to CID, then browse to get Adobe-GB1-0.cidmap and click OK. #FONTFORGE CHANGE POSTSCRIPT FONT NAME CODE#Two (or more) glyphs in this font have the code point. It's a little hard to detect this in normal use, but if you change the encoding to 'Glyph Order', and then use Edit->Select->Wildcard and enter the glyph name, both of them should be selected. We just need to edit the cidmap Adobe-GB1-4.cidmap in Fontforge directory and keep only lines for CID numbers from 0 to 7716 (This is compatible with GB2318 – Cf paragraph 2. When outputting a PostScript font only one of them will ever be seen. #FONTFORGE CHANGE POSTSCRIPT FONT NAME WINDOWS#In our example (simhei.ttf), which can be obtained from Microsoft Windows font directory, if we want to keep the glyphs for simplified Chinese, we can choose to use Adobe-GB1-0. Please check for further information on CJK/CID file for your language. We can use Fontforge with cidmap (Fontforge proprietary) and/or Cmap (from adobe) to perform this task. Using a glyphs subset adapted to your application.We can remove the bitmap to reduce the file size. ![]() When Fontforge opens such a file, it will ask whether to keep the bitmap or not. Some TrueType files embed a bitmap version of the font. ![]() Below we describe a method to reduce the file size with Fontforge using simhei.ttf, a CJK font as an example.įontforge is an open source font editor running under Linux and Windows/Cygwin. #FONTFORGE CHANGE POSTSCRIPT FONT NAME LICENSE#Designing and anycodings_.net producing fonts is a lot of tedious and anycodings_.net time consuming work, if you have a anycodings_.net proper license and need a custom version anycodings_.net of your font check with the designer or anycodings_.net the vendor, usually they are more than anycodings_.Embedded systems often have limited memory, that can be a challenge when your application requires Asian languages where fonts might be several megabytes large. Use the OT specifications to anycodings_.net check in what table which information is anycodings_.net stored in a font.Īlso, and this is probably the most anycodings_.net important thing: check your license if anycodings_.net you are allowed to change anything at anycodings_.net all in the fonts you have. anycodings_.net Editing the wrong thing, or not all the anycodings_.net things in fonts can render them anycodings_.net unusable. However: in all the cases you should anycodings_.net know what youâÂÂre doing. ItâÂÂs cheap (free), requires a anycodings_.net bit more work but is quite fun when anycodings_.net stringed up with shell and python build anycodings_.net scripts to batch edit bigger amounts of anycodings_.net font files. Single tables can be anycodings_.net merged back into the original font, anycodings_.net whole font TTX dumps get converted back anycodings_.net to completely new binary font files. TTX can dump all (or anycodings_.net specific) tables of a binary font into anycodings_.net readable XML files which can be edited anycodings_.net in a text editor. Nice touch: you can side anycodings_.net to side compare/edit multiple files.Ĭheap anycodings_.net (free) alternative. ![]() Quite a posh paid app that anycodings_.net lets you access and edit all the tables anycodings_.net inside a font. The newly produced font file anycodings_.net will work but will have lost a lot of anycodings_.net features.Īs a font engineer I use these tools on anycodings_.net a daily basis to work with binary font anycodings_.net files without destroying them: Most of the time anycodings_.net youâÂÂll lose big parts of your anycodings_.net OT Layout Features (glyph replacement, anycodings_.net mark positioning, sometimes even the anycodings_.net Kerning). When opening a binary font anycodings_.net file in an editor the editor tries to anycodings_.net reverse engineer the font, and that anycodings_.net almost never works out. ItâÂÂs better to use specified anycodings_.net tools used in font production anycodings_.net Workflows. ![]()
