saving images

Markus Dyck-2
Hello all - I almost hate to put this request on the list because it is
probably embarrassing. I am new to Image J, and have not found a way to
save images on which I performed certain measurements (i.e.,  am looking
at growth layers of teeth for ageing, and I want to save the images with
my lines and marks as reference for later if I want to check again). How
can I save the image with my "marks" or "drawings"?

Any assistance is greatly welcomed.

Thank you kindly, Markus

Hey Markus,

selections are only shown in an additional layer; if you want to have
them in the image, you need to draw them: Ctrl+D or Edit>Draw. This
turns the selection into "real pixels" in your image. You can define the
way how they are drawn under Edit>Options>Colors and Edit>Options>Line
Width.

cheers,
Michael

Hello all again, sorry to be a pain in the rear.

I need to ask for advice again regarding trying to save images with marks
on them.
Maybe I was not specific - here is what I do: I open an image (about 25MB
with good resolution to work with), I then use the drawing tool with
individual marks so I can mark certain points on the jpeg. For later
reference, I need to have these marks saved on the picture. I try save as
with different name, I try ROI and save, but whenever I am opening the
jpeg I renamed, only the picture opens with no marks I put on. Can any of
you epxerst on ImageJ please tell me how to do this step by step. I got
some advice from list members, but this seems not to work.

Thank you so much for your assistance - also have a good holiday season!

Hi Markus,

saving your marks in a jpeg is possible - simply create a line
or area selection and press "draw" or "fill" with a suitable
foreground color (color of the eyedropper tool).
If you have a big image, maybe you won't see a line if you view
it with less than 100% zoom factor: The line could be between
the pixels displayed on the screen.

Anyhow, you should NOT do this for the following reason:

Jpeg is a lossy compression, and each time you save the image,
more compression artifacts will creep in. Jpeg is especially bad
for sharp edges such as those of a line or dot used as a
marker.
So it is MUCH better if you don't save your markers with the
image but rather create, e.g. a point selection (shift-click
with the point selection tool to add points; double-click on
the tool to select whether they have numbers as labels).
Then, save it as a separate file via the ROI Manager:
Type "t" to add the selection to the roi manager, select the
selection(s) that you want to save and type "save".
BTW, doing it this way will also use much less disk space
(roi files are small).

If you want to automate it, a macro could save the roi with a
name related to the image in the same directory and another
macro could open the image and roi together.
Using the Macro Recorder (Plugins>Macros>Record) and having a
look at the macro documentation and sample macros
   http://rsb.info.nih.gov/ij/developer/index.html
should help.
