Image Set Flags

Almost all Mira Image Windows and command dialogs allow you to work with an Image Set as easily as with a single image. But oftentimes you may want to apply some command or procedure to only one image of the image set. For example you might want to measure statistics on only one of the 10 images displayed in an Image Window. You need a way to select whether an operation is performed on one image or on all images, and you need to be able to determine the current setting. Mira solves these problems by keeping track of 3 internal status Flags: one for processing image sets, another for measuring image sets, and a third one for plotting image sets.

Using Image Set Flags

Image Set Flags are used by Mira in each Image Window and as defaults for new windows. This software design lets you set default behavior for displaying new images and then to change the behavior inside each Image Window. When a new Image Window is opened, it inherits the default setting; at any time afterwards, you can change the behavior of each individual window. As you learn to use Mira you will discover the value of this capability when working with images. Here is how this works:

Global and Local (Window) Image Set Flags
Global Flags	Global flags are inherited as the default properties for each new Image Window. The global settings are changed using the Default Image Window dialog.
Local Flags	Initially, the default flags are also the local flags for each new Image Window. To change the Local flag settings, use the buttons on the Image Bar, the Image Set Toolbar, or use a menu command.

Image Set Flags
Process Image Set	Controls operations that affect pixel values, such as image arithmetic commands, listing header keywords, and also when adjusting the Transfer Function.
Measure Image Set	Controls operations that make measurements such as Centroid and Statistics.
Graph Image Set	Controls commands that graph or plot data from the image window, such as Column Profile Plot.

Toolbar Buttons

The Image Bar has 3 buttons that indicate the state of the image set flags for that particular window. These buttons are mirrored by buttons on the Image Set Toolbar.

Image Bar Buttons for Local Image Set Flags
	Sets the local Process Image Set flag for the window.
	Sets the local Measure Image Set flag for the window.
	Sets the local Graph Image Set flag for the window.

The state of the flags is indicated by the buttons as shown below for the Measure Image Set button circled in red:


Image Set Mode for measuring all images.	Single Image Mode for measuring a single image.

Changing the Local Image Set Flags

There are several ways to set or change the local image set flags. When an image window opens, it inherits the flags from the Default Image Window properties. These values may be changes for the current image window using the Image Bar buttons or the

Changing Default Image Set Flags

Open the Image Window Properties dialog using the View > Default Settings > Default Image Window command.
Check or uncheck the Process, Measure, or Graphing options as desired.
Save your changes to the profile or to a new profile.

Changing Local Image Set Flags for the Window

Select the Image Window of interest. Then use one of the following, equivalent methods to change the Flags:

From the Image Bar or Image Set Toolbar:

At the top of the Image Window is the Image Bar. Buttons for these flags are located on the right end of the toolbar (and at the top of the Image Set Toolbar).
Click the Process, Measure, or Graph buttons to set the desired state. You can tell the current state by letting the mouse hover over the button until the Tooltip appears. If the button is pressed (blue), image set will be processed, measured or plotted. If the button is out (black), only the active image will be processed, measured, or plotted. The state of the flags is indicated by the buttons as shown below for the Measure Image Set button circled in red:


	Image Set Mode for measuring all images.	Single Image Mode for measuring a single image.

From the Image Context Menu:

Right click on the image to open the Image Context Menu.
At the bottom, select the Image Set command. If an image set is displayed, the 3 flags will be enabled and can be set.
