我有這兩張圖片,我基本上在畫布上合併。現在我想將該畫布保存爲圖像。我應該怎麼做,或者如果有任何其他方式來合併兩個圖像。Android合併兩張圖片
我的示例代碼 -
Bitmap bmp1 = BitmapFactory.decodeResource(getResources(),
R.drawable.duckpic);
Bitmap bmp2 = BitmapFactory.decodeResource(getResources(),
R.drawable.img);
// canvas.drawColor(Color.BLACK);
// canvas.drawBitmap(_scratch, 10, 10, null);
Bitmap bmOverlay = Bitmap.createBitmap(bmp2.getWidth(), bmp2
.getHeight(), bmp2.getConfig());
// Canvas cs = new Canvas(bmp2);
canvas.scale((float) 0.5, (float) 0.5);
canvas.drawBitmap(bmp2, new Matrix(), null);
canvas.drawBitmap(bmp1, new Matrix(), null);
canvas.save();
我得到它的工作通過這樣做 -
cs = Bitmap.createBitmap(c.getWidth(), c.getHeight(), Bitmap.Config.ARGB_8888);
Canvas comboImage = new Canvas(cs);
comboImage.drawBitmap(s, new Matrix(), null);
comboImage.drawBitmap(c, new Matrix(), null);
comboImage.save();
// this is an extra bit I added, just incase you want to save the new
// image somewhere and then return the location
String tmpImg = String.valueOf(System.currentTimeMillis()) + ".png";
OutputStream os = null;
try {
os = new FileOutputStream("/sdcard/" + tmpImg);
cs.compress(CompressFormat.PNG, 100, os);
} catch (IOException e) {
Log.e("combineImages", "problem combining images", e);
}
基本上,它在這裏給出 - http://www.jondev.net/articles/Combining_2_Images_in_Android_using_Canvas
