imgcf (Image Processing Toolbox User's Guide)

Image Processing Toolbox User's Guide

Get handle to most recent current figure containing an image

Syntax

```
hfig = imgcf
```

Description

hfig = imgcf returns the handle of the most recent 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, imgcf creates a new figure.

Note

imgcf can be useful in getting the handle to the Image Tool figure window. Because the Image Tool turns graphics object handle visibility off, you cannot retrieve a handle to the tool figure using gcf.

Example

imtool rice.png
cmap = copper(256);
set(imgcf,'Colormap',cmap)
