我正在使用以下代码.图像被保存,但它是黑色的.
请看我的代码,告诉我我做错了什么.
我在菜单中使用这个代码.

case R.id.id_menu_Save: Bitmap bmp = SavePixels(0,800,400,CCDirector.sharedDirector().gl); File file = new File("/sdcard/test.jpg"); try { file.createNewFile(); FileOutputStream fos = new FileOutputStream(file); bmp.compress(CompressFormat.JPEG,100,fos); Toast.makeText(getApplicationContext(),"Image Saved",0).show(); Log.i("Menu Save Button","Image saved as JPEG"); } catch (Exception e) { e.printStackTrace(); } break;
这是我的保存图像功能.
public static Bitmap SavePixels(int x,int y,int w,int h,GL10 gl) { int b[]=new int[w*(y+h)]; int bt[]=new int[w*h]; IntBuffer ib=IntBuffer.wrap(b); ib.position(0); gl.glReadPixels(x,w,y+h,GL10.GL_RGBA,GL10.GL_UNSIGNED_BYTE,ib); for(int i=0,k=0; i<h; i++,k++) {//remember,that OpenGL bitmap is incompatible with Android bitmap //and so,some correction need. for(int j=0; j<w; j++) { int pix=b[i*w+j]; int pb=(pix>>16)&0xff; int pr=(pix<<16)&0x00ff0000; int pix1=(pix&0xff00ff00) | pr | pb; bt[(h-k-1)*w+j]=pix1; } } Bitmap sb = Bitmap.createBitmap(bt,h,Bitmap.Config.ARGB_8888); return sb; }
除此之外,我想要的是指出我的方向正确.喜欢如果我得到屏幕的像素,我应该探索什么类/实体?
只需将SavePixelx方法更改为:
