create a resize / compress image

Compress and Resize the Image
 

Bitmap compressBitmap(String file, int width, int height) {

  BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
  bmpFactoryOptions.inJustDecodeBounds = true;
  Bitmap bitmap = BitmapFactory.decodeFile(file, bmpFactoryOptions);
  int heightRatio = (int) Math.ceil(bmpFactoryOptions.outHeight
    / (float) height);
  int widthRatio = (int) Math.ceil(bmpFactoryOptions.outWidth
    / (float) width);
  if (heightRatio > 1 || widthRatio > 1) {
   if (heightRatio > widthRatio) {
    bmpFactoryOptions.inSampleSize = heightRatio;
   } else {
    bmpFactoryOptions.inSampleSize = widthRatio;
   }
  }
  bmpFactoryOptions.inJustDecodeBounds = false;
  bitmap = BitmapFactory.decodeFile(file, bmpFactoryOptions);
  return bitmap;
 }

create a new image file in cache memory

 

public File gettempImagefile(Bitmap bitmap) {
  // create a file to write bitmap data
  File f = new File(context.getCacheDir() + "imges.jpg");
  try {
   f.createNewFile();
  } catch (IOException e) {
   e.printStackTrace();
  }
  ByteArrayOutputStream bos = new ByteArrayOutputStream();
  bitmap.compress(CompressFormat.JPEG, 90 /* ignored for PNG */, bos);
  byte[] bitmapdata = bos.toByteArray();
  // write the bytes in file
  FileOutputStream fos;
  try {
   fos = new FileOutputStream(f);
   fos.write(bitmapdata);
   return f;
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  return null;
 }

How to use / call this methods

 

File image = gettempImagefile(compressBitmap(imagePath, 250, 250));
