MATLAB: Display an image in Its Original Size

Question

Can we show an image in its original size in MATLAB?

Right now when we are showing, it is exactly fitted to the image window size. However, I want to show the image

Answer 1

There are 3 things to take care of in order to display image in its original size (1:1):

• The figure size and units.
• The axes size and units.
• The axes data aspect ratio.

Once all of that are set according to the image size even using MATLAB's image() function one could generate 1:1 display of an image.

Here is the sample code:

%% Load Data

mI = imread('7572939538_04e373d8f4_z.jpg');

numRows = size(mI, 1);
numCols = size(mI, 2);


%% Setings

horMargin = 30;
verMargin = 60; %

The result (Based on the image - Landscape by Roman Vanur):
