-The variable m_height is the size of the font muliplied by 64.
+The variable `m_height` is the size of the font muliplied by 64.
 It will be used to set font size with:
 
-- FT_Set_Char_Size if m_resolution is set (> 0)
-- FT_Set_Pixel_Sizes, divided by 64, if m_resolution is not set (= 0)
+- `FT_Set_Char_Size` if m_resolution is set (> 0)
+- `FT_Set_Pixel_Sizes`, divided by 64, if m_resolution is not set (= 0)
 
 The method height() returns m_height / 64;
