[英]How to get a high resolution image
My problem is, when I take a picture from camera and passing to another activity. 我的问题是,当我从相机拍摄照片并传递到其他活动时。 The image is not in high resolution.
图像不是高分辨率的。 How can I make my image in high resolution.
如何以高分辨率制作图像。 my codes below
我的以下代码
Main Activity 主要活动
Button btn_cam = (Button) findViewById(R.id.btn_cam);
btn_cam.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
MainActivity.this.startActivityForResult(intent, CAMERA_PIC_REQUEST);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK) {
Bitmap image = (Bitmap) data.getExtras().get("data");
Intent cam = new Intent(this, MainCam.class);
cam.putExtra("flostic", image);
startActivity(cam);
Second Activity 第二次活动
Intent intent = getIntent();
imageBitmap = (Bitmap) intent.getParcelableExtra("flostic");
Add an MediaStore.EXTRA_OUTPUT
to the intent,and give path in putExtra
to specify path for picture saving, because otherwise it only returns a snap of picture not a high resuolution picture. 将
MediaStore.EXTRA_OUTPUT
添加到该意图中,并在putExtra
提供路径以指定图片保存路径,因为否则,它仅返回图片快照而不是高分辨率图片。 Refer this doc . 请参阅此文档 。
Standard Intent
action that can be sent to have the camera application capture an image and return it. 可以发送以使相机应用程序捕获图像并将其返回的标准
Intent
动作。 The caller may pass an extra EXTRA_OUTPUT
to control where this image will be written. 调用方可以传递一个额外的
EXTRA_OUTPUT
来控制该图像的写入位置。 If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. 如果不存在EXTRA_OUTPUT,则会在Extra字段中将一个小型图像作为Bitmap对象返回。 This is useful for applications that only need a small image.
这对于只需要较小图像的应用程序很有用。 If the
EXTRA_OUTPUT
is present, then the full-sized image will be written to the Uri
value of EXTRA_OUTPUT
. 如果存在
EXTRA_OUTPUT
,则将全尺寸图像写入EXTRA_OUTPUT
的Uri
值。
