drwl

A simple header-only library utilizing fcft and pixman for primitive rendering of text and rectangles. See the 'example' folder for a rudimentary program to render some text.

drwl_destroy() will destroy any associated Img or Fnt objects; if the drwl contexts Img or Fnt is managed by the user, they must be set to NULL beforehand by using drwl_setimage and drwl_setfont respectively.

API

int drwl_init(void);
void drwl_fini(void);
Drwl *drwl_create(void);
void drwl_setfont(Drwl *drwl, Fnt *font);
void drwl_setscheme(Drwl *drwl, uint32_t *scm);
void drwl_setimage(Drwl *drwl, Img *image);
void drwl_destroy(Drwl *drwl);
Fnt *drwl_font_create(Drwl *drwl, size_t count, const char *names[static count], const char *attributes);
void drwl_font_destroy(Fnt *font);
Img *drwl_image_create(Drwl *drwl, unsigned int w, unsigned int h, uint32_t *bits);
void drwl_rect(Drwl *drwl, int x, int y, unsigned int w, unsigned int h, int filled, int invert);
int drwl_text(Drwl *drwl, int x, int y, unsigned int w, unsigned int h, unsigned int lpad, const char *text, int invert);
unsigned int drwl_font_getwidth(Drwl *drwl, const char *text);
unsigned int drwl_font_getwidth_clamp(Drwl *drwl, const char *text, unsigned int n);
void drwl_image_destroy(Drwl *drwl);

bufpool

A tiny header-only library for handling boilerplate with dual wl_buffer caching; requires _GNU_SOURCE on Linux systems.

Usage

BufPool pool;
DrwBuf *buf = bufpool_getbuf(&pool, shm, width, height);
drwl_setimage(drwl, buf->image);
drwl_rect(drwl, 0, 0, width, height, 1, 1);
drwl_setimage(drwl, NULL);
wl_surface_attach(surface, buf->wl_buf, 0, 0);
bufpool_cleanup(&pool);
drwl_setimage(drwl, NULL);
drwl_destroy(drwl);
