MATLAB: How to display an image which occupies the entire screen and has no borders

borderfigurefillfullscreengrayimageMATLABmaximizemenubarscreenwindow

I want to display an image such that it occupies the entire screen. I also want to eliminate the window borders including the menu bar.

Best Answer

The ability to display an image in full screen is not possible in MATLAB. A workaround would be to maximize the figure programmatically and eliminate both the window borders and the menu bar.

A sample code is provided below:

I = imread('rice.png');
figure; imshow(I)
set(gcf,'MenuBar','none')
set(gca,'DataAspectRatioMode','auto')
set(gca,'Position',[0 0 1 1])

MATLAB: FullScreen of a Figure with no Borders and Toolbar

Fed - according to http://www.mathworks.com/matlabcentral/answers/102219-how-do-i-make-a-figure-full-screen-programmatically-in-matlab, you could create your full screen figure as

 hFig = figure('units','normalized','outerposition',[0 0 1 1]);

So if you have displayed your image using either imshow or image as

 image(myimg)

then you can change the size as

 % get the figure and axes handles
 hFig = gcf;
 hAx  = gca;
 % set the figure to full screen
 set(hFig,'units','normalized','outerposition',[0 0 1 1]);
 % set the axes to full screen
 set(hAx,'Unit','normalized','Position',[0 0 1 1]);
 % hide the toolbar
 set(hFig,'menubar','none')
 % to hide the title
 set(hFig,'NumberTitle','off');

Try the above and see what happens!

MATLAB: How to remove colorbar and heatmap black borders

If you want to remove the colorbar, you can set the ColorbarVisible property to 'off':

h = heatmap(magic(5));
h.ColorbarVisible = 'off';

Alternatively, use the colorbar command:

heatmap(magic(5))
colorbar off

Heatmap does not provide any control over the borders around each cell, so if you want to remove the borders, you will have to switch to a lower-level function like image or surface.
