is there a way to read jpeg-file for example 2000x3000 pixels and write a new jpeg-file with 200x300 pixels?

Is there any where a ready solution for this problem?

I thank you!

Sizing an image and reading/writing JPEG files are two different things. Use of JPEG codecs is covered in the FAQs.

In order to resize an image, simple do this:

Image source = ...;

BufferedImage target = new BufferedImage(200, 300, BufferedImage.TYPE_INT_ARGB); // What type?

Graphics g = target.getGraphics();
g.drawImage(source, 0, 0, 200, 300, (ImageObserver)null);

Good luck,
