示例1: save_screenshot
void save_screenshot(const char *dir, const char* name, const Annotation& ann = Annotation()) {
char filename[PATH_MAX];
int ret = snprintf(filename, sizeof(filename), "%s/%s.png", dir, name);
assert(ret >= 0 && (size_t)ret < sizeof(filename));
auto screenshot = u8x8_bitmap_to_cimg<uint8_t>(&u8g2, 3, black, white);
screenshot.resize(screenshot.width() * SCREENSHOT_SCALE, screenshot.height() * SCREENSHOT_SCALE);
// Create a bigger output image
size_t width = screenshot.width() + 2*SCREENSHOT_BORDER + (ann.margin[LEFT] + ann.margin[RIGHT]) * SCREENSHOT_SCALE;
size_t height = screenshot.height() + 2*SCREENSHOT_BORDER + (ann.margin[TOP] + ann.margin[BOTTOM]) * SCREENSHOT_SCALE;
auto output = CImg<uint8_t>(width, height, 1, 3, /* value for all channels */ 255);
// Draw the screenshot in the center
output.draw_image(translate_x(0, ann), translate_y(0, ann), 0, 0, screenshot);
// Draw a 1px border around the screenshot, just inside the
// SCREENSHOT_BORDER area (leaving a bit of white space between
// the border and the screenshot).
draw_outline(output, ann.margin[LEFT] * SCREENSHOT_SCALE, ann.margin[TOP] * SCREENSHOT_SCALE, screenshot.width() + 2 * SCREENSHOT_BORDER, screenshot.height() + 2 * SCREENSHOT_BORDER, grey);
ann.annotate(output);
output.save_png(filename);
printf("Generated %s\n", filename);
