If not installed, run\n`sudo apt install gnome-screenshot`.\n\n## Example\n\nYou can use `screenshot()` to take a screenshot easily.\n\n``` r\nlibrary(screenshot)\nsc <- screenshot()\nsc_image <- imager::load.image(sc)\nplot(sc_image)\n```\n\nTo locate image from a screenshot, use `locate_image()`. In this case,\nbottom left corner of screenshot image was cut off as needle image.\n\n``` r\nsc <- screenshot()\nsc_image <- imager::load.image(sc)\nw <- 100\nh <- 80\npos_x <- 1\npos_y <- imager::height(sc_image) - h\nneedle <- hay2needle(sc_image, pos_x, pos_y, w, h)\n(locate_image(needle)) # center location\npos <- locate_image(needle, center = FALSE)\nfound <- hay2needle(sc_image, pos[1], pos[2], w, h)\nlayout(c(1:3))\nplot(sc_image)\nplot(needle)\nplot(found)\n```\n\nOn Windows, clipboard image can be saved by `save_clipboard_image()`.\n\n``` r\npath_img <- \"path_of_png_file\"\nsave_clipboard_image(path_img)\nshell.exec(path_img)\n```\n\n## Caution (=0.9.0)\n\n- Automatically adjusted in 0.9.1 and latter.\n\nWhen changing display DPI scaling, need to adjust position.\n\n``` r\n # when using 125%\npos <- locate_image(IMAGE_TO_CLICK) / 1.25\nKeyboardSimulator::mouse.move(pos[1], pos[2])\nKeyboardSimulator::mouse.click()\n```\n\nYou can see display scale in setting app as shown below.\n\n
