示例1: getFrameBufferPixmap
import com.badlogic.gdx.utils.viewport.Viewport; //導入方法依賴的package包/類
public Pixmap getFrameBufferPixmap(Viewport viewport) {
int w = viewport.getScreenWidth();
int h = viewport.getScreenHeight();
int x = viewport.getScreenX();
int y = viewport.getScreenY();
final ByteBuffer pixelBuffer = BufferUtils.newByteBuffer(w * h * 4);
Gdx.gl.glBindFramebuffer(GL20.GL_FRAMEBUFFER, fbo.getFramebufferHandle());
Gdx.gl.glReadPixels(x, y, w, h, GL30.GL_RGBA, GL30.GL_UNSIGNED_BYTE, pixelBuffer);
Gdx.gl.glBindFramebuffer(GL20.GL_FRAMEBUFFER, 0);
final int numBytes = w * h * 4;
byte[] imgLines = new byte[numBytes];
final int numBytesPerLine = w * 4;
for (int i = 0; i < h; i++) {
pixelBuffer.position((h - i - 1) * numBytesPerLine);
pixelBuffer.get(imgLines, i * numBytesPerLine, numBytesPerLine);
}
Pixmap pixmap = new Pixmap(w, h, Pixmap.Format.RGBA8888);
BufferUtils.copy(imgLines, 0, pixmap.getPixels(), imgLines.length);
return pixmap;
