Maximum opencv image size?

Question

Qt

What is the maximum image file size to work with in opencv?

Answer 1

The image size is width * height * bytes per pixel. For grayscale, this is one byte per pixel. For BGR - 3 bytes per pixel (+ alignment? not vkurse here). For rgba - 4 bytes per pixel.
The limit is the amount of RAM or how much memory can be addressed to one process. You can reduce memory consumption by processing the image in parts.
But in theory, if we talk about image sizes, then we have a limit for uint for width and height.
