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.
