C++ (Cpp) Region::contains Examples

Example #1

File: cursor.cpp Project: poplax/aseprite

static void clearpixel(ui::Graphics* g, const gfx::Point& pt, gfx::Color color)
{
  if (saved_pixel_n < MAX_SAVED) {
    if (clipping_region.contains(pt))
      g->putPixel(saved_pixel[saved_pixel_n++], pt.x, pt.y);
    else if (!old_clipping_region.isEmpty() &&
             old_clipping_region.contains(pt))
      saved_pixel_n++;
  }
}

Example #2

File: cursor.cpp Project: poplax/aseprite

static void drawpixel(ui::Graphics* graphics, const gfx::Point& pt, gfx::Color color)
{
  if (saved_pixel_n < MAX_SAVED && clipping_region.contains(pt)) {
    if (cursor_negative) {
      int c = saved_pixel[saved_pixel_n++];
      int r = gfx::getr(c);
      int g = gfx::getg(c);
      int b = gfx::getb(c);

      graphics->putPixel(color_utils::blackandwhite_neg(gfx::rgba(r, g, b)), pt.x, pt.y);
    }
    else {
      graphics->putPixel(color, pt.x, pt.y);
    }
  }
}

Example #3

File: cursor.cpp Project: poplax/aseprite

static void savepixel(ui::Graphics* g, const gfx::Point& pt, gfx::Color color)
{
  if (saved_pixel_n < MAX_SAVED && clipping_region.contains(pt))
    saved_pixel[saved_pixel_n++] = g->getPixel(pt.x, pt.y);
