Bug #487
closedmap pop up in imageviewers measures image distance in nm and that of power spectrum in the same
100%
Description
For real space image, it should be in angstrum now that everywhere else is in angstrum. For Fourier space, the distance should be in resolution ( larger pixel distance the smaller the number).

Fix this with r13956.
To test:
1. Find an image with pixelsize and particle size known. For example, 10apr29b_00028gr_00090sq_v04_00024hl_00004ea.mrc pixelsize is 1.66 Angstrum, and GroEL top view diameter in there is ~150 A.
2. Click on the image to show the map.
3. Click on the ruler tool and click on the two ends of a top-view disk-like GroEL particle. The measured distance should show ~ 150 A.
4. In the viewer activate FFT display and click on it to show its map.
5. Click on the ruler tool and measure the x-axis resolution limit by clicking on the center of the FFT (power spectrum) image as the first point and the left-edge at the same horizontal line ( i.e. only move in x not y). The measured result should show 2 * 1.66 Angstrum.
6. Click on two points that has a smaller distance, the resolution measured should have a larger number than 2 * 1.66 Angstrum.

Code looks ok to me.

Anke, could you test this?

I tested it and it works.
