最重大的當然就是 - 不理會 fontconfig 的設定,下面幾個 issues 可能是同一問題

  • Issue 18159: Chrome doesn't honor fontconfig settings
  • Issue 12179: System font hinting settings are not obeyed
  • Issue 29871: Chrome font rendering seems fuzzy compared to Firefox (on Linux)(這個 bug 有附比較多圖,其實,有些人家回報 chrome 太模糊的我反而覺得比較好看)
  • Issue 29817:font rendering

另外,Chrome 對於字型 kerning 的解讀還需要加強 (相當有趣的發現!)

  • Issue 21207: Font rendering issue: kerning doesn't match Firefox

還有偽粗體的問題 (直接看 Issue 中的圖比較清楚)

  • Issue 22360: synthesized bold (fake bold) glyphs get horribly blurred when native bold is not availble

雖然TTF的BCI相關專利在Apple手中,沒記錯的話OSX是完全沒有作hinting的!

看來覺得Chrome字型很糊鬧的,不是只有我一人... :)

據說 chromium 用了 freetype-freeworld 就不會糊鬧了。

freetype-freeworld 可以找找 srpm 來看是怎麼編的。

我可以確定,光是系統裝freetype-freeworld是沒有用的!因為我無法忍受沒有hinting的字型,所以都有裝。

不曉得chrome是否類似open office的作法,是用自己套件內的freetype函式庫。

看到這篇,查了一下: 

chrome 關於內嵌點陣字向量字型的幾個相關 bug

  • Issue 18333: Embedded bitmap font is primarily used for rendering Japanese texts instead of anti-aliased one
  • Issue 21149: Support fontconfig's flag for embedded bitmaps.
  • Bug 39894 - [chromium] respect the user's embedded bitmap settings on Linux.
