The routine gSetPointChars() switches the current character mode to 'point' hardware character mode. It differes from normal hardware mode in that only standard hardware point sizes are selected for output. Thus only the height specification of a character size request is used. This mode takes effect when characters are subsequently output provided there has been no intervening call to gSetSoftChars() or gSetCharTransformMode(GON).
When 'point' hardware character mode is active, GINO attempts to select the nearest point size available using the requested angle and italic setting. If the device cannot generate these, then non-angled and non-italicized character-generation is attempted, and if this fails, GINO will search for the nearest size of characters that the device can generate. If the device can generate no characters at all, they will be generated by GINO just as if gSetSoftChars() was called. Appendix B specifies what character generation facilities are provided by the device.
