Why do I get an error when I am trying to write to a file using IMWRITE in MATLAB 7.8 (R2009a)?
Show older comments
I am trying to write to a file with IMWRITE function. I am trying to create a path to a file in a folder that does not exist:
Z = peaks; surf(Z)
axis tight
set(gca,'nextplot','replacechildren');
surf(sin(2*pi/20)*Z,Z);
F = getframe;
imwrite(F.cdata,'newFolder/testfile.jpeg','jpg')
I get the following error:
ERROR: ??? Error using ==> imwrite at 409
Can't open file "newFolder/testfile.jpeg" for writing.
You may not have write permission.

You need to make sure that the path to file that you specify for IMWRITE exists. You can use MKDIR command to create the directory. Consider the following example:
mkdir('newFolder')
imwrite(F.cdata,'newFolder/testfile.jpeg','jpg')
For more information on the MKDIR function, please refer to the documentation by executing the following in the MATLAB command prompt:
doc mkdir
