When I select points in an image, I would like to drag the image and select the points, but if I drag the image, I couldn't continue with ginput

I need a solution for that

for example say I would like to select 10 points by using ginput. after selecting 5 points I would like to drag the image and then would like to select remaining 5 points



Thank you,



Best Regards,
Paheerathan

try using the "button" third argument of ginput.
selecting point with the left button, scrolling with the right.
(i don't think you can drag, but just to pan between 2 right mouse clicks)

Dear exosceleton,

I need what you mentioned. I would like to pan it in between the point selection. Please provide me a sample code.

When I selecting the point pan is disabled. How to make it enabled?

Thanks,


Regards
Pahee

it's not a solution it is more a workaround;

use left and right mousebuttons

%%%%%%%%%
clear all
h1=figure;
load mandrill
imagesc(X)
colormap(map)
done=0;
i=1;
while done==0
[x,y,button]=ginput(1);
if button==1
Xarray(i)=x;
Yarray(i)=y;
i=i+1;
else
XL=xlim;
YL=ylim;
xlim([x-((XL(2)-XL(1))/2) x+((XL(2)-XL(1))/2)]);
ylim([y-((YL(2)-YL(1))/2) y+((YL(2)-YL(1))/2)]);
end
if i==10
done=1;
end
end
Xarray
Yarray
