示例1: calculateInSampleSize
import com.google.vr.sdk.widgets.pano.VrPanoramaView.Options; //导入依赖的package包/类
private int calculateInSampleSize(
BitmapFactory.Options options, int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
final int halfHeight = height / 2;
final int halfWidth = width / 2;
// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
while ((halfHeight / inSampleSize) > reqHeight
&& (halfWidth / inSampleSize) > reqWidth) {
inSampleSize *= 2;
}
}
return inSampleSize;
}
示例2: decodeSampledBitmap
import com.google.vr.sdk.widgets.pano.VrPanoramaView.Options; //导入依赖的package包/类
private Bitmap decodeSampledBitmap(InputStream inputStream) throws IOException {
final byte[] bytes = getBytesFromInputStream(inputStream);
BitmapFactory.Options options = new BitmapFactory.Options();
