How to calculate java BufferedImage filesize

Question

I have a servlet based application that is serving images from files stored locally. I have added logic that will allow the application to load the image file to a Buffered

Answer 1

Before you load the image file as a BufferedImage make a reference to the image file via the File object.

File imgObj = new File("your Image file path");
int imgLength = (int) imgObj.length();

imgLength would be your approximate image size though it my vary after resizing and then any operations you perform on it.
