C++ (Cpp) _expose_tethered_mode Examples

Example #1

File: tethering.c Project: AdamMajer/darktable

void expose(dt_view_t *self, cairo_t *cri, int32_t width, int32_t height, int32_t pointerx,
            int32_t pointery)
{
  cairo_set_source_rgb(cri, .2, .2, .2);
  cairo_rectangle(cri, 0, 0, width, height);
  cairo_fill(cri);

  // Expose tethering center view
  cairo_save(cri);

  _expose_tethered_mode(self, cri, width, height, pointerx, pointery);

  cairo_restore(cri);

  // post expose to modules
  GList *modules = darktable.lib->plugins;
