Changing image orientation while saving to file

f6df8302-abef-455f-9673-7dcd611acd52

I get a Base64Encoded image string (GIF format) from an external system. While reading the byte array and saving the image to file, the image gets saved in landscape orientation.

The code snippet is below.

String image = "R0lGODdhCAcgA=";

Base64Coder decoder = new Base64Coder();

byte [] decodeBytes = decoder.decode(image.getBytes());

ByteArrayInputStream stream = new ByteArrayInputStream(pngArray);

BufferedImage bImage = ImageIO.read(stream);

File label = new File("C:/labels/test.gif");

ImageIO.write(bImage, "gif", label);

I want to save the image in portrait orientation. Is there a way to do that?

This isn't clear. Is the image already in the orientation you want?

Looks like ImageIO doesn't support that but third party libraries do.

See if you can use the solution in this thread:
