Dear ImageJ Users,

In my current project, I use ImageJ more as a library then directly as a
tool. We have some constraints, which makes it better this way. For this
reason I do not work with visible ImageJ windows on my desktop. This works
fine, here is a example

// get the a image from somewhere:
ImagePlus image_red = m_array.getRedImage();

// do some processing:
WindowManager.setTempCurrentImage(image_red);
IJ.run("Enhance Contrast", "saturated=0.5 normalize equalize");
IJ.run("Red");

image_red.updateImage();

Especially this is fine, as I can test my problems in ImageJ and then
integrate this directly into my programme.

With this I have one problem: I can not use plugins and functions that are
using more than the "TempCurrentImage", for example the following
commands:

- Merge RGB...
- Image Calculator...

Does anybody know a solution, that I can do the following without
displaying images on the screen?

// some not working code, that should demonstrate what I want to do:
// get the a images from somewhere:
ImagePlus image_red = m_array.getRedImage();
ImagePlus image_green = m_array.getGreenImage();

// do some processing:
WindowManager.setTempCurrentImage("red", image_red);
WindowManager.setTempCurrentImage("green", image_green);

IJ.run("RGB Merge...", "red=[red] green=[green]");

Thank you very much,

Andreas
