我正在尝试将图像发送到服务器.在发送之前,我正在减小其尺寸和质量,然后解决任何轮换问题.我的问题是,在旋转图像后,当我保存它时,文件比以前更大.旋转尺寸为10092之前,旋转之后为54226

// Scale image to reduce it
Bitmap reducedImage = reduceImage(tempPhotoPath);

// Decrease photo quality
FileOutputStream fos = new FileOutputStream(tempPhotoFile);
reducedImage.compress(CompressFormat.JPEG, 55, fos);
fos.flush();
fos.close();

// Check and fix rotation issues
Bitmap fixed = fixRotation(tempPhotoPath);
if(fixed!=null)
{
    FileOutputStream fos2 = new FileOutputStream(tempPhotoFile);
    fixed.compress(CompressFormat.JPEG, 100, fos2);
    fos2.flush();
    fos2.close();
}

public Bitmap reduceImage(String originalPath)
{
    // Decode image size
    BitmapFactory.Options o = new BitmapFactory.Options();
    o.inJustDecodeBounds = true;
    o.inPurgeable = true;
    o.inInputShareable = true;
    BitmapFactory.decodeFile(originalPath, o);

    // The new size we want to …
