从网址撷取影像，并保持其原始大小 [英] Fetch image from Url and keep its original size

问题描述

我从这个code座网址提取图片：

I fetch image from URL with this code block:

BitmapFactory.Options bmOptions;
bmOptions = new BitmapFactory.Options();
//from web
try {
    Log.i(TAG,""+g.getPath());
    InputStream is = new URL(g.getPath()).openStream();
    BitmapFactory.decodeStream(is, null, bmOptions);
    is.close();
    BitmapFactory.Options o2 = new BitmapFactory.Options();
    o2.inSampleSize = 2;
    o2.inMutable = true;
    is = new URL(g.getPath()).openStream();
    bitmap = BitmapFactory.decodeStream(is, null, o2);
    is.close();
} catch (Exception ex) {
    ex.printStackTrace();
}

下载成功，但图像的大小不是原大小。这是较低的分辨率。我怎样才能在其原大小图片从网址是什么？

Download is successful but the image's size is not the orginal size. It is lower resolution. How can I get the image in its orginal size from Url?

推荐答案

删除此行

    o2.inSampleSize = 2;

您也可以使用
                  位= BitmapFactory.de codeStream（是，空，bmOptions）;

You can also use bitmap = BitmapFactory.decodeStream(is, null, bmOptions );

没有必要创造新的BitmapOptions

No need to create new BitmapOptions
