Hi Ken,

Yes, you can do this.

Put the cursor where you want to zoom.
Press the + key repeatedly to reach the desired zoom level. Maximum zoom is 3200% -- more than enough to see pixels.
Make a rectangular ROI.  Use the - (minus) key to zoom out as needed and adjust the corners.
Image > Crop to complete the cropping.

Hope this helps,
Theresa

Have some ~ 40 MP JPEGs that I want to be able to zoom  right in, eg >400%,
until I can clearly see individual pixels, and then set a crop line.

Is this possible with ImageJ?

If yes would appreciate suggestions.

Thanks

Ken
