UF_DRF Callbacks

UF_DRF_begin_line_fn_t (view source)

Defined in: uf_drf_types.h

Overview

Callbacks for UF_DRF_render_text. Default set is used for other functions.

Each return either UF_DRF_RENDER_OK or
UF_DRF_RENDER_CANNOT_RENDER_CHAR (UF_DRF_draw_char_fn_t only) or
UF_DRF_RENDER_CANNOT_RENDER_SYMBOL (UF_DRF_draw_user_symbol_fn_t only).

If a cannot render or not drawn status is returned for a user symbol or an
individual character, the resultant object will be stroked.

Lines are output as polyline segments bracketed by calls to
the begin and end line functions.
