接下来的示例说明怎样进行截屏并且保存为PNG格式。

public class ScreenshotFactory { private static int counter = 1; public static void saveScreenshot(){ try{ FileHandle fh; do{ fh = new FileHandle("screenshot" + counter++ + ".png"); }while (fh.exists()); Pixmap pixmap = getScreenshot(0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight(), false); PixmapIO.writePNG(fh, pixmap); pixmap.dispose(); }catch (Exception e){
} }

private static Pixmap getScreenshot(int x, int y, int w, int h, boolean yDown){ final Pixmap pixmap = ScreenUtils.getFrameBufferPixmap(x, y, w, h); if (yDown) { ByteBuffer pixels = pixmap.getPixels(); int numBytes = w h 4; byte[] lines = new byte[numBytes]; int numBytesPerLine = w 4; for (int i = 0; i < h; i++) { pixels.position((h - i - 1) numBytesPerLine); pixels.get(lines, i * numBytesPerLine, numBytesPerLine); } pixels.clear(); pixels.put(lines); }

return pixmap;
