Hello,

I have my .fig plot image, and I want to recover the array of this image inside the figure. In other words, how I can back from fig into .png image and making sure that I am saving my image with the same dimension as the original one.

Thank you.

See for example: How do I extract data from MATLAB figures?

Use the saveas function to save the resulting figure as a .png image.

However if yiou created the .fig file, you should have the data used to create it.

Thank you, but I dont have the data of the figure, I took it like this.

Any idea?

The .fig file has all the data used to plot it, so it is relatively straightforward to recover it (although it takes some effort). See the first link in my Answer to understand how to recover the data from it.
