[SOLVED] File open dialog in ImageJ Javascript Script

File open dialog in ImageJ Javascript Script

I want to write a macro/script to open a file open dialog, and then import the selected image using BF with various options.

I found this JS script for doing the latter part here:

importClass(Packages.loci.plugins.BF);
importClass(Packages['loci.plugins.in.ImporterOptions']); // 'in' is a reserved word, hence the different syntax
importClass(Packages.loci.common.Region);

var path = "/path/to/file";
var options = new ImporterOptions();
options.setId(path);
options.setAutoscale(true);
options.setCrop(true);
options.setCropRegion(0, new Region(x, y, w. h));
options.setColorMode(ImporterOptions.COLOR_MODE_COMPOSITE);
var imps = BF.openImagePlus(options);

imps[0].show();

I also found the regular macro language file open dialog here:

File.openDialog(title)

How do I do both of these things in a JS script? Specifically, how do I create the file open dialog in JS?

If it is easier to do both in the macro IJM language, rather than Javascript, then how do I create a BF object and set the import options?

Solution

All the ImageJ macro functions are implemented in ij.macro.Functions, so you can find what you need in Functions.java

From Javascript, you can use ij.io.OpenDialog:

importClass(Packages.ij.io.OpenDialog);

od = OpenDialog("Choose a file", null);
folder = od.getDirectory();
file = od.getFileName();
path = folder + file;

Alternatively, you can use the option string of the Bio-Formats Importer macro command, it's all in the macro you linked to:
```
run("Bio-Formats Importer", "open=" + path + "autoscale color_mode=Default view=Hyperstack stack_order=XYCZT");
```
To get the required options, simply use the macro recorder.
