Image Processing Toolbox

Setting Toolbox Display Preferences

The behavior of imshow is influenced in part by the current settings of the toolbox preferences. Depending on the arguments you specify and the current settings of the toolbox preferences, imshow may:

• Suppress the display of axes and tick marks.
• Include or omit a "border" around the image.
• Call the truesize function to display the image without interpolation.
• Set other figure and axes properties to tailor the display.

All of these settings can be changed by using the iptsetpref function.The truesize preference can also be changed by setting the display_option parameter of imshow. This section describes how to set the toolbox preferences and how to use the display_option parameter.

When you display an image using the imshow function, MATLAB also sets the Handle Graphics figure, axes, and image properties, which control the way image data is interpreted. These settings are optimized for each image type. The specific properties set are described under the following sections:

• The Image and Axes Properties of an Indexed Image
• The Image and Axes Properties of an Intensity Image
• The Image and Axes Properties of a Binary Image
• The Image and Axes Properties of an RGB Image
