To be implemented by a derived class to choose what GlyphRender to use when the transformation matrix (see Painter::transformation()) does not have perspective.
- Parameters
-
| logical_format_size | the format size at which the glyphs of a GlyphRun or GlyphSequence are formatted |
| transformation | the transformation matrix from logical (i.e. item) coordinates to normalized device coordinates, i.e. the value of Painter::transformation(). |
| viewport_size | width and height of the |
| max_singular_value | the largest singluar value the transformation matrix concacted with the viewport transformation |
| min_singular_value | the smallest singluar value the transformation matrix concacted with the viewport transformation |

- Parameters
-
| logical_format_size | the pixel size at which the glyphs of a GlyphRun or GlyphSequence are formatted |
| transformation | the transformation matrix from logical (i.e. item) coordinates to normalized device coordinates, i.e. the value of Painter::transformation(). |
| viewport_size | width and height of the |
