Images, Figures and Graphics Objects in MATLAB


by Foster N.



This book describe the different data and image types, and give details about how to read, write, work with, and display graphics images; how to alter the display properties and aspect ratio of an image during display; how to print an image; and how to convert the data type or graphics format of an image. Graphics objects are interdependent, so the graphics display typically contains a variety of objects that, in conjunction, produce a meaningful graph or picture. This book explians how handle graplhics objects. Graphics objects are the basic drawing elements used by MATLAB to display data. Each instance of an object has a unique identifier called a handle. Using this handle, you can manipulate the characteristics (called object properties) of an existing graphics object. You can also specify values for properties when you create a graphics object. This book also discusses the features that are implemented through figure properties and provides examples of how to use these features. Figure graphics objects are the windows in which MATLAB software displays graphics. Figure properties enable you to control many aspects of these windows, such as their size and position on the screen, the coloring of graphics objects displayed within them, and the scaling of printed pictures.
