imgcf

Get current figure containing image

Syntax

fig = imgcf

Description

example

fig = imgcf returns the current figure that contains an image. The figure may be a regular figure window that contains at least one image or an Image Tool window.

If none of the figures currently open contains an image, then imgcf creates a new figure.

Examples

collapse all

Open an image in an Image Tool window.

I = imread('strawberries.jpg');
imtool(I)

Use the handle of a figure containing an Image Tool window to center the window on the screen.

sz = get(groot,'ScreenSize');
pos = get(imgcf,'Position');
pos = [(sz(3)-pos(3))/2 (sz(4)-pos(4))/2 pos(3) pos(4)];
set(imgcf,'Position',pos)

Output Arguments

collapse all

Current figure containing an image, returned as a figure object.

Tips

  • imgcf can be useful in getting the figure used by the Image Tool. You cannot retrieve the tool figure using gcf.
