Hi folks,

I'm displaying a JPEG image in my app and currently, the axes stretch the image when the window is maximised. Is there a way to make the axes the same size as the image, so that it doesn't stretch the image to maximise the window?

Thanks

Hi Teshan,

Since you have mentioned axes, I'm assuming you are using uiaxes to display the image. However, MATLAB has uiimage function for displaying images inside applications. This function also has the Name-Value pair ScaleMethod giving users the control over how the image must be displayed when the component area changes.

Hope this helps

Thanks Rashed, is there a way to incorporate this using the App designer, since I only see the option to include a uiFigure or uiAxes there?

在 MATLAB Online 中打开

In the App designer component library, there is an Image component which can be used in the Design View tab. You can access the ScaleMethod property once the image component is present in the component area. Alternatively you can use the following code in the Code View

img = uiimage(app.UIFigure,'ScaleMethod','none','ImageSource','image.jpg')

Hope this helps
