image - convert does not do anything

Timo Pietilä
Hello everyone.

I'm not actual ImageJ user but IT support and I have a client that is
trying to convert one image to another form using fiji imageJ, and
process should be as easy as

file - open,
image - type - 8-bit,
image -convert.

However result is "A ImgPlus is required but none exist"

According to her everything worked just about two months ago.

I have hard time finding what that "convert" even should be doing, it
isn't in documentation, no youtube tutorials even have it in that menu
so I really don't have any clue how to debug this problem.

I'm basically giving myself a real crash course of ImageJ at this point.

Any ideas, clue,s anything?

Greetings Timo,

it would help, if you could tell us by which means* your client tries to
perform the image type conversion and which kind of image she starts
from, i.e. where does the original image come from, which suffix does it
have and which bit-depth.

*) ImageJ means:
ImageJ GUI use
ImageJ macro use
ImageJ plugin use

Regards

Herbie

Suggestion:

Perhaps your client uses the ImageJ-menu command:

Process >> Batch >> Convert...

that is described in the ImageJ user-guide (subsection "29.12.2 Convert…"):
<https://imagej.nih.gov/ij/docs/guide/146-29.html#toc-Subsection-29.12>

Re: image - convert does not do anything

Timo Pietilä
No, there is just plain convert at the four bottom items at image -menu.
That's the one she tried to use and which gives that error. I can
replicate the error in my own work machine.

I'm at home now, so can't remember what the other three were, however
none of those are documented in documentation.

In fact that menu is quite a bit longer than the one described in
documentation. More than four items are missing from there.

When I get to work machine I can post what it looks like in my machine.

Hi Timo,

The IMAGE/Type/8-bit menu item in itself performs the conversion to
8-bit.  You might want to uncheck the EDIT/Options/Conversions default
of "scale when converting" if you need to preserve the data range (else
it will scale the results to fit your requested range).

You can record the steps using the macro recorder and just run the
script as needed.

open();
run("Conversions...", " ");
run("8-bit");

Hope that clears things up.

In reply to this post by Timo Pietilä
Dear Timo,
From what you are describing I have really hard time to understand what you are trying to do.
Could you please go to Plugins>Macros>Record... try again your wished workflow and send us the generated code?
Put maybe the used picture as available.
And very stupid question: are you using an up to date version of ImageJ (Help>Update_UmageJ...)?
My best regards,
Philippe

"A ImgPlus is required but none exist"
Is this the exact error message?

If so, this is not a text from the original ImageJ source.

Could it be that a custom plugin is installed?

Re: image - convert does not do anything

Herbie
In reply to this post by Timo Pietilä
Sorry Timo,

but I have no idea what you are speaking of.

There is no ImageJ-menu named -menu. What menu items are you referring
to and which of the ImageJ-menus do you mean?

What does *plain* convert mean?

Can I conclude that your client uses the ImageJ-GUI?

Please be more precise and detailed, otherwise we won't be able to help.

Regards

Herbie

Re: image - convert does not do anything

Gabriel Landini
In reply to this post by Timo Pietilä
Hi,
In Fiji, that "convert" command is not part of IJ, but part of Fiji's imagej-
ops0.45.5,jar

If you type "convert" in the box under the menu, you can look at the source
code which takes you to

https://github.com/imagej/imagej-ops/blob/imagej-ops-0.45.5/src/main/java/net/
imagej/ops/commands/convert/ConvertImgPlus.java

You probably have to contact the authors of that file.

There is another "Convert..." under the Process>Batch menu. Perhaps your user
is intending to use that one?

Cheers

Gabriel

Re: image - convert does not do anything

Herbie
Timo,

as Gabriel tells us, there is a menu item "Convert" that, however is
part of Fiji, not ImageJ. Please note that opposite to the claim that
Fiji is just ImageJ, this is not the case...

I can't find any description of the functionality of this command, but
here are the source and the coder that may be contacted for further details.
<https://github.com/imagej/imagej-ops/tree/imagej-ops-0.45.5/src/main/java/net/imagej/ops/convert>

Regards

Herbie

Thanks, this helps quite a lot. Now I at least have a direction where to
find additional info. Previously had no idea how to proceed further and
not just bang my head to the wall.

Re: image - convert does not do anything

Curtis Rueden-2
Hi all,

The "Image > Convert" command was an obsolete experimental command (one of
several) included with ImageJ Ops. I removed the following such commands
from the menus:

* Image > Convert
* Image > Convolve
* Image > Threshold > Project
* Image > Threshold > Apply Threshold

Run Help > Update... (not Help > Update ImageJ) to get the updated
imagej-ops library.

Regards,
Curtis

Re: image - convert does not do anything

Timo Pietilä
Thanks, that removed the menu item.

What did it do when it still was there? My client has used it before, so
I might need to tell her how to do the same without that menu item.
