example

truesize(fig,[mrows ncols]) adjusts the display size of an image in a figure, fig, to the dimensions [mrows ncols], in pixels.

truesize(fig) adjusts the display size such that each image pixel covers one screen pixel.

If you do not specify a figure, truesize adjusts the display size of the current figure.

Examples

collapse all

Open Live Script

Create a default checkerboard image, which has size 80-by-80 pixels. Display the checkerboard image to fill the full size of the figure window. The image is magnified to fill the window.

c = checkerboard;
imshow(c,'InitialMagnification','fit')

Display the checkerboard image so that each image pixel covers one screen pixel.

truesize

You can adjust the size of the figure window to arbitrary dimension. The image scales to fit within the figure window.

truesize([300 200]);

Input Arguments

collapse all

Figure containing a single image or a single image with a color bar, specified as a figure handle. By default, truesize uses the current figure, with handle gcf.

Screen dimensions (in pixels) that the image should occupy, specified as a 2-element numeric row vector. By default, [mrows ncols] is equal to the image size, so each image pixel covers one screen pixel.
