Working with Images

pd.show_image

With py4pd you can display images inside PureData patches using Python, you can use the pd.show_image method. This method is essentially a copy of the else/pic object, but with an interface that allows you to easily show images from within your Python code.

Supported extensions

You can just use .png, .gif, and .ppm image formats.

• Example

  Bring scores to PureData.
