You just imread() the file.
  • .bmp - limit 32767 x 32767
  • .gif - limit 65535 x 65535
  • .jpg - limit 65535 x 65535
  • .png - limit 1073741823 x 1073741823
  • .tiff - limit 65535 x 65535 (maximum 4 Gigabytes per image)

Hi @Ali Al-Janabi,
To read an image of size 2048x2048 pixels using MATLAB R2013a, imread() function can be used. Here is how you can accomplish this.
img = imread('test.jpg'); % Change test.jpg with your file name
imshow(img);
% Check the size of the image
imageSize = size(img);
disp(['Image size: ', num2str(imageSize)]);
  • Ensure that the image file is located in your current working directory or specify its full path.
Refer to the following documentation for more details about the function:
  1. imread (MATLAB R2024b): https://www.mathworks.com/help/matlab/ref/imread.html
  2. Use command "doc imread" in the command window of R2013a for the documentation of that release.
