| mask | bitmask of options. |
| value | bitmask indicating which options are set on. |
| mask_high | if high bit is set in the first mask byte, this set of bits is added to mask. |
| value_high | if high bit is set in the first mask byte, this set of bits is added to value. |
| mask_high2 | if high bit is set in the second mask byte, this set of bits is added to mask. |
| value_high2 | if high bit is set in the second mask byte, this set of bits is added to value. |
| names_length | length of names string |
| names | one or more font names to attempt to use |
| size | desired size of text |
| size_units | enumeration describing how size is interpreted |
| size_tolerance | indicates acceptable size difference for fixed-size bitmap fonts |
| tolerance_units | enumeration describing how tolerance is interpreted |
| transforms | enumeration indicating how text string is affected by modelling matrix |
| rotation | rotation of characters relative to the horizontal (in degrees). value of -1 indicates characters are rotated to lie along the text path |
| slant | amount of slant applied to characters (in degrees) |
| width_scale | horizontal scaling applied to the entire text string |
| extra_space | additional space added between characters |
| extra_space_units | enumeration describing how extra space is interpreted |
| line_spacing | distance between baseline of multi-line strings, as a multiple of the font height |
| greeking_limit | limit below which text may be replaced by simple geometry |
| greeking_limit_units | enumeration describing how greeking limit is interpreted |
| greeking_mode | enumeration describing to handle text below the greeking limit |
| renderer | enumeration describing limitation on font type |
