saveas TIFF without get filelist

[Emanuele Martini]

Hi to all,
I have a problem with saving as tiff an opened image in a macro/function.

I write a macro that open an image from a path and process it and then want to save to a saving folder:
1) open image_path=path/image1.tif
2) doing something
3) save to save_path=save_dir/PR_image1.tif

I try with this code saveAs("TIFF", save_dir + "PR_" image_name);
where save_dir is a string path like = "path/ema/exp1"
and i retrieve the image name after opening the image using getTitle().

someone has some ideas to figure out from this, I think, simple problem?
Thanks,
Emanuele Martini

P.S.: the name of the image and the save_dir sometimes have spaces...so maybe it could be a problem

P.S.: i used sometimes, in other macros and plugin, the solution with
image_path=getDirectory("Choose image folder");
save_dir=getDirectory("Choose saving folder");
list = getFileList(image_path);
and then iterate in a for
saveAs("TIFF", save_dir+"PR_"+list[i]);
and that works fine...
but in this case I would have a function that operate on a single file like that:
extract(image_path,save_dir)

Try

 saveAs("TIFF", save_dir + "PR_" +image_name);

Yes I try with it...
sorry i lost a plus in my first post.
My try that doesn't work is exactly that :)
saveAs("TIFF", save_dir + "PR_" +image_name);

I really think that is a problem of spaces presents in my path and in my image name...but i don't know how to resolve it.
Thank you,
Emanuele

Spaces should not be a problem but you need to add a path separator if ‘save_dir’ does not end with one. The following example, which has a space in both the path and in the image name, works as expected:

  dir = "/Users/wayne/Images/test dir";
  name = "image name.tif";
  saveAs("tif", dir +"/" +name);

Without seeing the macro I can't tell, but often these things need the file
separator function:
*File.separator*

Hi to all,
and thank you all.
I resolved; the problem was that i had not create the directory (with File.makeDirectory(save_dir)) before saving.

Have a nice day,
Emanuele
