I read Seth Popinchalk's post on locating code in m-files rather than in the mask fields. I'd like to do this with my "icon drawing commands" which draws a background image and/or labels ports.

All works fine if I do this in the "icon drawing commands" field of the mask:

image(imread('pic.jpg'))
port_label('input', 1, 'my_input')

But if I put it in DrawMyIcon.m and call that m-file in the "icon drawing commands," then I get a separate figure popping up.

My ultimate aim here is to make this, like the rest of my code, encrypted/obfuscated pcode for distribution to customers.

My problem was that my drawMyMask.m file looked like this:

function drawMyMask
image(imread('pic.jpg'))
port_label('input', 1, 'my_input')

The thing throwing it off was the first line -- it needed to be a straight script, not a function. Delete the "function" line, and all works.
