How to give pizel (0,0) a physical dimension

[bateman]

Hello,

I have written a plugin, the next stage of my plugin involves calibration of the image. The only information that I have is the top left pixel's physical distance i.e. pixel (0,0) is really (-200,200) in physical space and the pixel dimension. I want to be able to set (0,0) as (-200,200) and calibrate the image (using Calibration class) with the physical dimension of each pixel.

I have had a look at the Calibration class in the ImageJ Api. Are there any suggestions?

Thanks

I have scowered Google and I have no clue on how to set an individual pixel to a given physical dimension!

Any ideas at all would be greatly appreciated!
