Show image of variable Simulink model in Matlab GUI

I have created a GUI with GUIDE to run simulink models, change parameters, etc. I would like an image of the flowsheet to appear in one of the GUI's tabs. For the default flowsheet, I have an image (screenshot) of it and use imshow in the axes CreateFcn. However, as the users can modify the flowsheet or create new ones, I won't have an image for each of them created. Do you know if is there any function to generate an image of the flowsheet? I read that it is not possible to integrate the simulink editor within the Matlab GUI, is that ok?

Thank you very much in advance.

What is flowsheet ?

If you want to display the image of simulink model in your GUI then you can follow the below steps

• Suppose your model is MyModel.mdl and you want to display image or root level of model.
• Open the model

open_system('MyModel')

• Save snapshot of your model in an image file & close model

print -sMyModel ModelImg.jpg -djpeg 
close_system('MyModel')

• Read & display generated image file in GUI

ImgData = imread('ModelImg.jpg')

Thank you very much. However, the quality of the image is not very good. Do you know how could I improve it? (I rotated it using rot90).

A flowsheet is the flowchart in a process (inputs and outputs streams, processes, etc.)

For good quality image, you can save the it in 24 bit BMP format using

print -sMyModel ModelImg.bmp -dbmp 
close_system('MyModel')

JPEG is compressed image format which gives image in smaller file size with reduced quality.

Please accept answer if it helped.

The result is the same for both formats. Any other options?

I don't know why. Try

print -sMyModel ModelImg.bmp -dbmp16m

It makes the image slightly bigger but of similar or even worse quality
