TICKIT_REN...UFFER_CLIP(3) Library Functions Manual TICKIT_REN...UFFER_CLIP(3) NAME tickit_renderbuffer_clip, tickit_renderbuffer_mask - restrict the draw- ing area of output functions SYNOPSIS #include <tickit.h> void tickit_renderbuffer_clip(TickitRenderBuffer *rb, TickitRect *rect); void tickit_renderbuffer_mask(TickitRenderBuffer *rb, TickitRect *mask); Link with -ltickit. DESCRIPTION tickit_renderbuffer_clip() restricts the clipping rectangle to the lim- its given, within the existing limits already set. This function cannot make the clipping region larger than it already was. tickit_renderbuffer_mask() applies a rectangular mask within the clip- ping region, masking off extra cells that can no longer be modified by the output functions. Unlike tickit_renderbuffer_clip() these regions can be arbitrarily positioned and discontinuous; each new call adds an- other masking region, rather than affecting the existing ones. To undo the effects of any of these functions, they should be used within nested pairs of calls to tickit_renderbuffer_save(3) and tickit_renderbuffer_restore(3). Both functions only affect the subse- quent drawing operations; they do not affect existing stored content, nor the behaviour of tickit_renderbuffer_flush_to_term(3). RETURN VALUE These functions return no value. SEE ALSO tickit_renderbuffer_new(3), tickit_renderbuffer_translate(3), tickit_renderbuffer(7), tickit(7) TICKIT_REN...UFFER_CLIP(3)
