Selecting Source Images
Source images are the images used by a command. Mira provides numerous ways to collect source images beyond the typical "display and process" architecture of most image processing applications. Most commands include a Source Image Selection control for this purpose. The [Select] button shown on the command dialog opens the Select Source Images dialog for collecting the images which will be fed back to the command. The Select Source Images dialog has 5 pages which each provide a distinct method for collecting the images to be processed.
The Select Source Images dialog is opened by clicking the [Select} button in the Source Image Selection Control which appears on most Mira command dialogs:
Clicking [Select} opens the Select Source Images dialog describe below. After returning from selecting source images, an abbreviated message shows the selection in the text field to the right of the button. Initially, if no images are selected, the text field lists none selected, as shown above.
The Image Window page selects images displayed in an Image Window. The list box contains the name of the current image for each Image Window on the Mira desktop. The window list is created when this dialog is opened, and it will be empty if no Image Windows are open.

The Folder page selects images from files in a folder. Optionally, several file selection rules may be used to filter which images will be selected from the folder. If no rules are used, then all files in the folder will be selected. This page remembers its settings between sessions, however it is possible that the listed folder may not exist in a new session.

The Drag from Explorer page provided a drop box where files can be dropped using the drag & drop protocol. Files are selected by marking them in Windows Explorer (the file manager), then dragged onto the box and dropped there by releasing the mouse button. The drop box is empty until files are dropped into it.

The Mira File List page is used for

List containing the selected files. The Mira File List is a
single text file containing the full path specification for 1 or

The Browse Files page opens a Windows Open dialog for selecting files. A powerful feature of this page is the Append option. This causes new files to be added to the list of files already in the box. The[Browse...] button activates the standard Windows Open dialog for selecting files. A limitation of the Open dialog is that it can only select files from a single folder at one time. Checking append allows you to browse for files multiple times, each time adding files from a new folder to the growing list in the box.
