How to snapshot a figure image without axis

Hi,

How do I save the image without axis or annotations etc, using GETFRAME. Just leave the image data.

Thanks.

set() the Visible property 'off' for anything you do not want to appear in the result. The outer edges and grid lines and tick marks and x/y/z labels can all be combined by

set(gca, 'Visible', 'off')

but if you have drawn any annotation('arrow') or the like then you will need to set those off as well; likewise if you used text() then you will need to set those handles Visible off as well.

To Add on to Walter Roberson answer,

You can remove the colour bar on the right by using .

colorbar('off');

That is by using the following code, you will be able to see a clean plot of the spectrogram output and save the plot in the current location with the name spect01.png.

set(gca, 'Visible', 'off');
colorbar('off');
saveas(gcf,'spect01.png');

Here gcf return the handle of the current figure.
