Could you please extent a bit or give some pointers?
This is now a bit off-topic.
I maintain at work a scanning electron microscope (SEM). Due to technical reasons the distance
between the pixels in x-direction is different from the y-direction. So you usually take SEM images
with 512x512 pixels, but get a rectangular, non-quadratic image.
The image format is TIFF and the pixel distance is specified in the TIFF header. Unfortunately the
only program that checks for the pixel distance is Windows' built in image viewer. In e.g. Adobe
Acrobat you have to specify the pixel distance manually to get a non-distorted image.
