Write Text on Image without increment of Size?

Question

I am writing some text on Image which will be compressed.

Image sie 2048 x 1536 Something px

I first tried to write first It throws OutOfMemory Exception

then i first compressed it to 1024 x 768

Then Written text on the Image

It increased the Image KB's from 100KB to 640KB

While writing text i can compromise the Image quality but not the text Quality

on Compression quality set to 30 the text also goes downsample

Questions:

1. is there any process to write then compress or Compress then Write
   text without changing the ImageSize(in KB)?

2. I want Image Size(in KB) as less as Possible?

3. And also When inSampleSize is set to 3 it does not work and only the image of 2048 , 1024 , 512 using 1 , 2 , 4 is created as output I want image of some size arround 700px maintaining aspect ration.

Method for StampingImage

public void stampMyImage(String filePath, String text, Bitmap bitmap) {
        String[] str = text.split("\n");
        filePath = "/sdcard/geoTag/1imagelong_001_001_0002_0002_1135_130708144229.jpg";
        bitmap = BitmapFactory.decodeFile(filePath);
        if (bitmap != null) {
            Bitmap dest = null;
            try {
                dest = bitmap.copy(bitmap.getConfig(), true);
            } catch (OutOfMemoryError e1) {
                Log.e("Exception", e1.getMessage());
                e1.printStackTrace();
            } catch (Error e) {
                Log.e("Exception", e.getMessage());
                e.printStackTrace();
            }
            Canvas cs = new Canvas(dest);
            Typeface tf = Typeface.create("Verdana", Typeface.BOLD);
            Paint tPaint = new Paint();
            tPaint.setAntiAlias(true);
            tPaint.setTextSize(40);
            tPaint.setTextAlign(Align.LEFT);
            tPaint.setTypeface(tf);
            tPaint.setColor(Color.RED);
            tPaint.setStyle(Style.FILL_AND_STROKE);
            cs.drawBitmap(bitmap, 0f, 0f, null);
            float textHeight = tPaint.measureText("yY");
            int index = 0;
            for (String Oneline : str) {
                cs.drawText(Oneline, 20f, (index + 1) * textHeight + 25f,
                        tPaint);
                index++;
            }
            try {

                        "/sdcard/timeStampedImage.jpg");
                dest.compress(Bitmap.CompressFormat.JPEG, 100, fos);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }
        }

Method for Regular Compression

 BitmapFactory.Options options = new BitmapFactory.Options();
    options.inSampleSize = 4;
    int quality = 70;
    myBitmapClose = BitmapFactory.decodeFile(imgUriClose.getPath(),options);
    if (myBitmapClose != null) {
        File sdImageMainDirectory = new File(imgUriClose.getPath());
        try {
        FileOutputStream fileOutputStream = new FileOutputStream(sdImageMainDirectory);
        BufferedOutputStream bos = new BufferedOutputStream(fileOutputStream);
        myBitmapClose.compress(CompressFormat.JPEG, quality, bos);
        if (bos != null) {
        bos.flush();
        bos.close();
        }
        if (fileOutputStream != null) {
        fileOutputStream.flush();
        fileOutputStream.close();
        }
        } catch (FileNotFoundException e) {
        e.printStackTrace();
        } catch (IOException e) {
        e.printStackTrace();
        }

Your problem is the allowed allocation memory for your app. When you load images to bitmap variables (decodeFile or bitmap.copy) try to set the options to decrease image quality. For example, when you do bitmap.copy try to set the options like this:

bitmap.copy(Bitmap.Config.ARGB_4444, true);
