The crop size is calculated after crop_offset right?

No, both crop_offset and crop_size are relative to the stitched canvas. The visual guide on the readme should help you.

Let's say the stitched image is 720x720, crop_offset is [0.5, 0.5] and the crop_size is [1.0, 1.0], then the cropped image is 360x360, right?

No, that would be invalid as the crop region would be outside the stitched canvas.

crop_size of [1.0, 1.0] would be the original size so there can't be any offset.

`crop_size` of `[1.0, 1.0]` would be the original size so there can't be any offset.

Oh, I see, so the crop_offset + crop_size won't exceed [1.0, 1.0]?
