I have a problem where the images (that are actually useful) rendered on Simulink blocks seem to lag Simulink in the sense that:
1. Scrolling through the model is grindingly slow.
2. When running the model it seems to force re-render all the mask images.
I use this method:
Does anyone know of a more efficient way of doing this?
One thing I like to do is storing the image data in the block user data.
I do not guarantee it will lead to great improvement, but it will save the call to IMREAD, replacing it by a get_param of the block user data.
It will make your model file bigger, but you will not need to carry image files anymore.
As Ryan point out, always make sure the size of the image reasonnable (you do not need 1024x768 pixels for a small block)
