[webkit-dev] Issues with font rendering on DirectFB build

[Sriram Neelakandan]

Hi Mike,

Even I found the same problem. tiny fonts on the FB screen !

I added some prints and noticed that the fontDescription.computedSize() was
1.0 for some reason. !!

so i added the following lines in the constructor of
WebCore/platfrom/graphics/gtk/FontPlatformDataGtk.cpp

*** FontPlatformDataGtk.cpp.org 2008-02-05 13:59:50.000000000 +0530
--- FontPlatformDataGtk.cpp     2008-02-12 16:29:20.000000000 +0530
*************** FontPlatformData::FontPlatformData(const
*** 47,56 ****
--- 47,64 ----
      int fcslant = FC_SLANT_ROMAN;
      int fcweight = FC_WEIGHT_NORMAL;
      float fcsize = fontDescription.computedSize();
+     if(fontDescription.computedSize() == 1.0)
+     {
+         /*fontDescription.setComputedSize(16.0);*/
+         m_fontDescription.setComputedSize(16.0);
+         fcsize = 16.0;
+     }
+
      if (fontDescription.italic())
          fcslant = FC_SLANT_ITALIC;
      if (fontDescription.bold())
          fcweight = FC_WEIGHT_BOLD;

This has temporarily fixed the problem.

I donot know the cause why the fontsize is computed as 1.0 !!
