Bitmap Of X Cm's Width And Y Cm's Height

I am taking a picture using camera in my app and will email the picture to a certain email address. now i want the emailed picture's physical dimensions to be 10cm's in width and 8

Solution 1:

This?

publicstaticintmm2pixels(int val, Context current) {
    DisplayMetricsmetrics= current.getResources().getDisplayMetrics();
    return (int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_MM, val, metrics);
}

Solution 2:

i have used WarrenFaiths directions and came up with the below solution.

DisplayMetricsmetrics= activity.getResources().getDisplayMetrics();
  totalDIP_X = metrics.xdpi;
  totalDIP_Y = metrics.ydpi;

totalDIP_X and totalDIP_Y represent the total number of DIPs per inch on the phone.

so if you want the bitmap to be 5cms*5cms on phone, which is equivalent to 1.968inch*1.968inch, we should use the below code.

  imageView1.setImageBitmap(Bitmap.createScaledBitmap (aBitmap, (int)(1.968*totalDIP_X), (int)(1.968*totalDIP_Y), false));
