機器人圖像轉換成BASE64的PHP

Question

製備Base64格式的圖像的方法，要寫入與一組標準圖像尺寸集大小的PHP服務器

Bitmap bm = Bitmap.createScaledBitmap(MediaStore.Images.Media.getBitmap(getContentResolver(), filePath), sizeW, sizeH, true) 

Answer 1

int sizeW=MediaStore.Images.Media.getBitmap(getContentResolver(), filePath).getWidth(); 
int sizeH=MediaStore.Images.Media.getBitmap(getContentResolver(), filePath).getHeight(); 
Matrix m = new Matrix(); 
m.setRectToRect(new RectF(0, 0,sizeW, sizeH), new RectF(0, 0, 300, 100), Matrix.ScaleToFit.FILL); 
Bitmap bm = Bitmap.createBitmap(MediaStore.Images.Media.getBitmap(getContentResolver(), filePath), 0, 0, sizeW, sizeH, m, true); 

//Bitmap bm = Bitmap.createScaledBitmap(MediaStore.Images.Media.getBitmap(getContentResolver(), filePath), sizeW, sizeH, true); 

ByteArrayOutputStream bao = new ByteArrayOutputStream(); 
bm.compress(Bitmap.CompressFormat.JPEG, 90, bao); 
byte[] ba = bao.toByteArray(); 
//Log.d("size200",String.valueOf((bm.getByteCount()/1024)/2)); 
ba1 = Base64.encodeToString(ba, Base64.DEFAULT); 
Log.e("base64-1", "-----" + ba1); 

的AsyncTask類：

public class uploadToServer extends AsyncTask<Void, Void, String> { 

     private ProgressDialog pd = new ProgressDialog(RegisterAds.this); 
     protected void onPreExecute() { 
      super.onPreExecute(); 
      pd.setMessage("send"); 
      pd.show(); 
     } 

     @Override 
    protected String doInBackground(Void... params) { 

      ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); 
      nameValuePairs.add(new BasicNameValuePair("base64", ba1)); 
      try { 
       HttpClient httpclient = new DefaultHttpClient(); 
       HttpPost httppost = new HttpPost(URL); 
       httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
       HttpResponse response = httpclient.execute(httppost); 
       String st = EntityUtils.toString(response.getEntity()); 
       Log.v("log_tag", "In the try Loop" + st); 

      } catch (Exception e) { 
       Log.v("log_tag", "Error in http connection " + e.toString()); 
      } 
      return "Success"; 

     } 

     protected void onPostExecute(String result) { 
      super.onPostExecute(result); 
      pd.hide(); 
      Log.d("nameimage", String.valueOf(name_image_upload_i1)); 
      new SummaryAsyncTask().execute((Void) null); 
      pd.dismiss(); 
     } 
    } 

使用：

new uploadToServer().execute(); 

PHP代碼：

<?php 
//error_reporting(E_ALL); 
if(isset($_POST['ImageName'])){ 
$imgname = $_POST['ImageName']; 
$imsrc = base64_decode($_POST['base64']); 
$save_path=$_SERVER['DOCUMENT_ROOT']."/news/upload/".$imgname; //.$data; 
header("Content-Type: bitmap; charset=utf-8"); 
$fp = fopen($save_path, 'w'); 
fwrite($fp, $imsrc); 
if(fclose($fp)){ 
echo "Image uploaded"; 
}else{ 
echo "Error uploading image";}} 
?> 

Answer 2

// method for bitmap to base64 
    public static String encodeTobase64(Bitmap image) { 
     Bitmap immage = image; 
     ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
     immage.compress(Bitmap.CompressFormat.PNG, 100, baos); 
     byte[] b = baos.toByteArray(); 
     String imageEncoded = Base64.encodeToString(b, Base64.DEFAULT); 
     return imageEncoded; 

    }
