Fixing points on a FITs Image

[Bernardo]

Hi there,

Sorry for coming back so soon to ask a question, but AIJ is so new for me....

I´d like to know if there´s a way to paint points of different colors directly over a FITs Image...I need to identify regions with different materials...

Thank you so much for your time,

Bernardo

Hi Bernardo,

You should be able to use any of the inherent ImageJ Region Of Interest (ROI) tools.

Look here for documentation on ROIs: https://imagej.nih.gov/ij/docs/guide/146-10.html

And here for Flood Filler: https://imagej.nih.gov/ij/docs/guide/146-19.html#toc-Subsection-19.16

I don't use those sorts of tools much, but the ImageJ documentation is fairly thorough at he above documentation site.

A couple of notes: Those ROIs will not be saved with the FITS image. You will need to output a .png or .jpeg image to present those later. To use some of the mouse moves, you will need to exit "Astronomy Mode" by clicking on a toobar icon to the left of the the one circled here:

Be sure you click on the circled icon again when you want to re-enter normal AIJ operation mode.
