Hi everybody,

I am trying to save live images with ImageJ by simply grabbing from the
computer screen with Shift+Ctrl+G (see attachment)

1) Is it possible to acquire the image without the menu of ImageJ program?

2) I'm using a 25 x 25 um grid for calibration. I wondered if the
calibration of 172 pixels per 25 um is correct (different measurements
give me slightly different values).

Thanks a lot in advance

Jose
