Using imshow(), set(gca, 'YDir', 'normal'), and ginput()

Hello,

I'm having a hard time dealing with the following issue. My intention is to set the Y direciton to normal in ginput without flipping the image I'm investigating. Here's my current code:

imshow('frame1.jpg');
hold on
set(gca, 'YDir', 'normal');
[x,y]=ginput(2);%click on body first, then head
hold off

However, this code also flips image 'frame1'. I'd appreciate it if anyone can help me find a way to prevent my image from getting flipped.

You will need to adjust the view() . Alternately, parent the image to a hgtransform and set the transform matrix so that the display comes out the way you want. Or third option: if you set the xdata and ydata properties of the image it is possible to get it to display upside down.

Have you considered just using flipud() ?

I think you will find that your requirements are inconsistent with using the results of ginput() to index into the image.
