opening file from macro

[Nilwik Rachel (BW)]

Hello everyone,

I have a question that I know for sure is quite simple, but I can't really find the right topic in the mailing list archive... perhaps I don't know what exactly to look for. The main problem is that I really don't have a clue about programming (and the commands used) in general...

The thing is, I open an image, perform some modifications and save the changed image in the same folder. Then, I want to open the original, unchanged image again, without closing the changed one. When using the macro recorder, I can of course manually open and save images, but this gives a code specifically for the image I am opening at that time, and I want it to work for other images as well.

I can imagine that there is a list with commands somewhere that I can use for this type of thing, could anyone perhaps give me a link?

Thanks so much!
Rachel



What I have until now is the following:

// After opening a file, first, retrieve the name+directory of the current image, without extension, for later use.
name = getTitle();
dotIndex = indexOf(name, ".");
image_name = substring(name, 0, dotIndex);
dir = getDirectory("image")

//then, some adjustments like split channels - thresholding etc

//Now, I would like to save the thresholded image separately, in the same directory as the original one and then re-open the original image.
// Or, perform the Split Channels tool without closing the original one...

Hi
http://rsbweb.nih.gov/ij/developer/macro/functions.html
The bits you want are under 'file' functions. But I suggest 'getFileList(directory)'
as a start, there are example macros on this. You can then reopen any time you like.
