Hi,
So far I understand that MATLAB Coder do not support using imread, imwrite etc, I wish to write the image data into a file and save it.
How can I achieve at MATLAB Coder?
Please help!
Thank you

You use coder.cevel() or similar techniques to call your own writing function passing in the data and the file name.
Depending on your target system, you might be able to take advantage of available third-party libraries such as libpng http://www.libpng.org/pub/png/libpng.html

Everybody says "just use these external libraries" to solve this apparently very common problem (no imwrite/imread in Coder) but I haven't been able to find a single example piece of code on HOW to do it.
Anyone have an example. It's my first foray into ceval.
Thanks ahead of time.
