Are Pixel Level Crops Possible with ImageJ?

[KenO]

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

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.

Hope this helps,
Theresa

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,

> Do not know the difference between ImageJ and Fiji

See the top of http://imagej.net/Fiji for an explanation. Please ask if
anything is not clear, so that we can improve the documentation.

The Windows Fiji downloads include a Java JRE, so you do not need to
install one separately.

However, the version bundled is Java 6 (1.6.0_24) which is very old, with
many bugs since fixed in Java 7 and Java 8. Personally I would advise using
a newer version of Java.

We will be updating the bundles later this year to include a newer version
of Java, as time allows [1]. In the meantime, you can certainly replace the
version of Java in the "Fiji.app/java" folder with your own preferred
version of the JRE.

Regards,
Curtis
