Hi Theresa,
Reason for late response is I had a number of projects to complete.
Thanks for the tip! "Put the cursor where you want to zoom. Press the + key repeatedly to reach the desired zoom level. Maximum zoom is 3200%"
As an ImageJ beginner I have tried to read the user guide and man but found no mention which is why I posted. Any recommendations concerning tutorials...
Would like to use ImageJ on different Windows PCs without installing so a portable ImageJ is what I would like to download.
Googled using "imagej portable windows" and found "Downloads - Fiji fiji.sc/Downloads Fiji Dec 22, 2014 - ImageJ will run on any system that has a Java 6 (or later) runtime installed. ... Windows XP, Vista, 7 or 8 with Java installed from java.com; Mac OS X 10.5 "Leopard" ... ImageJ and Fiji are distributed as portable applications."
Do not know the difference between ImageJ and Fiji so went to Fiji (software) wiki http://en.wikipedia.org/wiki/Fiji_%28software%29 and read "One of Fiji's principal aims is to make the installation of ImageJ, Java, Java 3D, the plugins, and further convenient components, as easy as possible. As a consequence, Fiji enjoys more and more active users."
As beginner this seems good to me, problem is the Windows PCs I use do not have Java 6 (or later) runtime installed.
Is there a version that has everything needed in a portable Windows app?
Thanks again for your help!
Ken

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
