use png to show agent

[omidedalati]

Hello,

I’m trying to display custom PNG images for agents instead of the default shapes using the agent_portrayal function. My portrayal code looks like this:

python
Copy
def agent_portrayal(agent):
return {
"Shape": "image",
"Image": "/local/resources/my_agent.png",
"scale": 0.9,
"Layer": 1
}
The images are located in a resources folder inside my project directory. I run the server from the project root using mesa runserver. However, the images do not display in the visualization, and only the default circle shape appears.

When I run the server from other directories, I see 404 errors in the console related to the images.

I am using the latest Mesa version. According to the documentation and examples (like the wolf_sheep example), this approach should work, but in practice, the images are not shown.

Is there any special configuration needed in the visualization or JavaScript files? Is there a way to use custom images without modifying the JS code?

I would appreciate any guidance

Hi! I took a look at your problem to see if I could help at all, it looks like you are calling fields which aren't supported by the visualization function. It seems like passing a custom shape and image isn't supported, but I could be wrong and maybe you're further along than I am.

Sorry that no one got back to you earlier.

I remember this working at some point. @Sahil-Chhoker, could you say what the latest status is on image support for agents in SolaraViz?

Images as markers are supported in the matplotlib backend, you can see this example to see the usage.
