impixel info - just coordinates
显示 更早的评论
Is it possible to obtain just the pixel x y vlaues from the impxelinfo command?
Im using this and want to get the X & Y seperately.
hp = impixelinfo;
set(hp,'Position',[5 1 300 20]);
Thanks Jason

At what point do you want to obtain/use the x and y values? Do you have some code that runs elsewhere (callback, periodically, or ..?) that needs to get this information? My understanding of this tool is that as you move the mouse cursor over the image, you will see the x,y coordinates and other values (depending upon image type) in the pixel info control. Do you then press the mouse button and expect that a callback will fire and use the current x,y coordinates of the image to do something?
From impixelinfo question, which is a similar question to yours, Ashish Uthama suggests either to use ginput or to grab the coordinate data as
childHandles = get(hp,'Children');
get(childHandles(1),'Tag')
ans =
pixelinfo text
get(childHandles(1),'String')
ans =
(153, 152) <112> [0.50 0.00 0.00]
where hp is the handle to your impixelinfo object. From the '(153, 152) .<112> [0.50 0.00 0.00]' string, you can figure out the x,y coordinates as 153,152.
