how to place an annotation one level deeper?

Hi,

I would like to place a small image into an annotation. It works if I don't choose a background color:

But I would like to set the background color to black (this makes the picture (i.e. the grayscale) invisible. So, how can I shift the annoation one level back or to shift the small image one layer up? Using FaceAlpha is not an option for me...

Thanks a lot

Could you share your images and your current plotting code for us to test with?

Why not create an overlaying axes instead of an annotation pane?

[Cris LaPierre]

I'm not aware of a way to order the layers. I think my approach would probably be to add a black shape in the image under the annotation. The annotation will move if the figure is resized.

% Add black shape in specified location
bx = mapshape([3541660 3541900 3541900 3541660],[5492180 5492180 5492250 5492250],'Geometry','polygon');
mapshow(ax,bx,'FaceColor','k')

thanks a lot, your idea works perfectly

yes, of course, here is the code:

GK=imread('Graukeil.jpg');
[A,R] = geotiffread('Kombi1b.tif');
figure('Renderer', 'painters', 'Position', [10 10 1200 800])
mapshow(A,R)
ax = gca;
ax.XRuler.Exponent = 0;
