Can I rotate the image (plot) #46

Thanks for the great work here! I wonder if there is any way to rotate the visualization of the data (output of function 'image'), such as flipping vertically or rotating 90 degrees. Sorry, I am not very familiar with the format of the visualization output. Many thanks!

For the image only, the easiest way to do this would be to change the image formula.

The default for ?Cardinal::image is intensity ~ x * y. You could pass the formula as intensity ~ y * x to flip the x/y axis, for example.

If you want to apply spatial transformations to the dataset itself, you can transform the coordinates in coord(obj) as you like.
