ImagePosition, FigPosition, and AxisPosition perplexity

Hello,

How to get the coordinates of the 4 corners of an image within a figure,

and how it relates to the figure position, the axis position, the xlimits, the ylimits, and possibly the PlotBoxAspectRatio.

also:

imshow('saturn.png');

% then eventually manipulate the figure position, the axis position, the xlim, the ylim.

%

% Why the following code below fails to get the proper image corners (lower left x-y point, width, height),

% in pixel units ?

axlim = get(gca,'Position')

fglim = get(gcf,'Position')

x1 = axlim(1)*fglim(3) + fglim(1);

x2 = (axlim(1)+axlim(3))*fglim(3) + fglim(1);

y1 = axlim(2)*fglim(4) + fglim(2);

y2 = (axlim(2)+axlim(4))*fglim(4) + fglim(2);

Thanks,

[Rik]

I'm not entirely certain the size of the axes object will change if the image requires a smaller window. You might need to get the position of the image object (perhaps by querying the XData and YData properties).
