4.3 File select dialogs

On most platforms you can drag files from your file manager directly to `nip2`'s main window. Alternatively, if you select `File` / `Open` in the main window, `nip2` will pop up a file dialog, see Figure 4.5. The open dialog has the following features:

Figure 4.5: Open dialog

Pin up button
  Normally the file dialog closes after you have opened something. If this item is checked, the dialog will stay up instead -- this is useful if you want to load or save a series of objects.

Image type select
  Use this menu to select the type of file you want `nip2` to display. There's a preference option to set the default image format. The VIPS file format is fast and accurate, but sadly not very widely supported (joke). You can also load and save images in TIFF, JPEG, PNG and PBM/PGM/PPM formats. The save options related to these formats can be changed in the `JPEG save`, `TIFF save`, `PNG save` and `PBM/PGM/PPM save` columns in the preferences workspace. You can usually load in many more formats, it depends how your `nip2` has been configured.

Show thumbnails
  Pressing this button pops up a window which shows thumbnail-sized images for all the matching files in the current directory.

Bookmarks
  The box and buttons down the left show your bookmarks. You can add and remove bookmarks with the two buttons below.

Location
  Press the path buttons at the top of the dialog to move up and down a series of directories. If you press Ctrl-L you can type (or copy-paste) an exact location.

The save dialog is a little different, see Figure 4.6. The save dialog has the following extra features:

Increment button
  If pin up and increment are both selected, then after a save `nip2` will attempt to add one to the selected file name. For example, if you save a file called `fred001.v`, after the save `nip2` will put the name `fred002.v` into the selected file name box. Again, this is useful if you want to save a series of images.

Browse for other folders
  If you click this, the save dialog opens up and you can see the current set of files and browse to other directories.
