Question

I am using the command WARP in image processing in MATLAB.

[x,y,z] = cylinder;
I = imread('testpat1.png');
warp(x,y,z,I);

Above is the example code for using WARP given in MATLAB. But I am not able to save the output of this command. If I do imwrite, just 1 X 1 matrix is saved.

Can anyone help me this ?

Thanks in advance

You should be able to use the following line of code to get the handle to the resulting surface object:

h = warp(x, y, z, I);

You can then access properties of that surface using get(h, 'property')

A list of the available properties is here

For example if you want to get the X coordinates you would do: Xcoords = get(h, 'XData');

hope that helps!

This is based on the comments below.

fig = figure, warp(x, y, z, I);
print(fig, '-r80','-dtiff','image2.tif')
