Manage Display Preferences
You can use Image Processing Toolbox™ preferences to control certain characteristics of how imshow
and the Image Viewer app display images on your screen. For example, using toolbox
preferences, you can specify the initial magnification used.
Retrieve Values of Toolbox Preferences
To determine the current value of Image Processing Toolbox preferences, you can look in the Preferences dialog box or use the
iptgetpref
function.
To open the Preference dialog box, click Preferences in the
Home tab in the MATLAB® desktop. In the Preferences dialog box, select Image Processing Toolbox. You
can also access Image Processing Toolbox preferences from the Image Viewer
File menu, or by typing iptprefs
at the command
line.
To retrieve the values of Image Processing Toolbox preferences programmatically, type iptgetpref
at the
command prompt. The following example uses iptgetpref
to retrieve the
value to determine the value of the ImtoolInitialMagnification
preference.
iptgetpref('ImtoolInitialMagnification')
ans = 100
Preference names are case insensitive and can be abbreviated. For a complete list of
toolbox preferences, see the iptprefs
reference page.
Set Values of Toolbox Preferences
To set the value of Image Processing Toolbox preferences, you can use the Preferences dialog box or use the
iptsetpref
function.
To open the Preference dialog box, click Preferences in the
Home tab in the MATLAB desktop. In the Preferences dialog box, select Image Processing Toolbox. You
can also access Image Processing Toolbox preferences from the Image Viewer
File menu, or by typing iptprefs
at the command
line.
To specify the value of a toolbox preference, use the iptsetpref
function. This example calls iptsetpref
to specify that
imshow
resize the figure window so that it fits tightly around
displayed images.
iptsetpref('ImshowBorder','tight');
For a table of the available preferences, see the iptprefs
reference page.
