Stretching of characters is mainly based on [[MathML:CompositeChars_and_Variants|Composite Characters and Variants]]. Thus, improvement of stretching is highly related to a better [[MathML:Fonts|font support]]. | |||

{{bug|414277}} | For various reasons, stretching may be imperfect: the user's system lacks mathematical fonts, we do not support yet the stretching for a particular char or we do not have a glyph of suitable size. Using a scale transform {{bug|414277}} would allow to workaround the issue of non-stretched characters and improve the accuracy of stretching. Note that as in TeX, an imperfect stretching causes issues such that | ||

{{bug|552290}} | The MathML spec mentions diagonal arrows as an example of characters that stretch both in vertical and horizontal directions. We already support stretching of horizontal/vertical arrows using a composite char. The idea of {{bug|552290}} is to apply a rotation on this composite char to implement diagonal direction. We should add direction:updiagonal and direction:downdiagonal in our operator dictionary to distinguish this diagonal stretching. If we want a general mechanism, an attribute like basechar:\UNNNN should also be added to indicate on which char we should apply the rotation (i.e. a horizontal arrow in our case). | ||
