How to combine images without loading them into RAM in Java

2020-08-02 • Java

I have a very large image (around a gigapixel) that I want to generate. So far, I can only create an image of about 400000 pixels in buffered image, and then there will be an out of memory error I want to build the image piece by piece, and then combine these fragments without loading the image into memory I can also do this by writing each part to a file, but imageio does not support this operation
