This section describes different data and image types and gives details about how to read, write, work with, and display graphics images.
Types of images supported by MATLAB graphics.
This example shows how to read an RGB image into the workspace and display it.
Reduce memory requirements by storing images as 8-bit or 16-bit unsigned integers.
Work with standard image file formats in MATLAB, such as reading and writing image files.
Display graphics file images and control the size and aspect ratio.
Like all graphics objects, the image object has a number of properties you can set to fine-tune its appearance on the screen.
Print images in proper proportions by preserving the aspect ratio.
Converting between data types changes the interpretation of the image data.
