Hi
I have a simple code snippet that displays an image on screen and should put
up cross hairs about the mouse location and should, when the mouse is clicked
returns the mouse position on the image. MatLab works fine but you get no
cross hairs on octive and a mouse click causes the program to crash.

Did I miss something ??


% Select Image File 
[i_filename, i_pathname, i_filterindex] = uigetfile('*.tif','Select Image');

%Open file
image_file = strcat(i_pathname, i_filename);

% read tiff image
Test = imread(image_file);

%Display Image
image(Test);

%Get mouse click position
[x1,y1] = ginput(1)

Octive Command Window Output:
>> pkg load image
>> pkg load control
>> pkg load signal
>> pkg list
