Question

I want to save an image from a designated axes. I keep getting You may not have permission to write error. Here is my code for the save as push button:

axes(handles.axes3);
[FileName, PathName] = uiputfile('*bmp', 'Save As');
Name = fullfile(FileName, PathName);
imwrite(handles.TReg, Name, 'bmp');

Also, handles.TReg is a transformed image defined on another function.

I cannot seem to find my error here, any thoughts would be appreciated.

Edit
If I use the code:

axes(handles.axes3);
[FileName, PathName] = uiputfile('*bmp', 'Save As');
Name = fullfile(FileName, PathName);
imwrite(handles.TReg, 'Name', 'bmp');

The file will save as Name.bmp in the proper directory. However I did notice that when I try saving with the original code, the error also reads (I missed this bit sorry):

Can't open file "Image1\C:\Users\Shinobii\Documents\MATLAB\" for writing.

I think the pathname should read like

"C:\Users\Shinobii\Documents\MATLAB\Image1"

could this be the problem?

Small mistake:

[FileName, PathName] = uiputfile('*.bmp', 'Save As'); %# <-- dot
Name = fullfile(PathName,FileName);  %# <--- reverse the order of arguments
imwrite(img, Name, 'bmp');

Also its a good idea to check that the user didn’t cancel the dialog box:

[FileName, PathName] = uiputfile('*.bmp', 'Save As');
if PathName==0, return; end    %# or display an error message
