The Zip Download block creates a binary object. The Blob URL block creates a URL where that object can be accessed. | |
Dataflow: The Mouse Event block converts a dropped image to binary as described here. Next, the Blob URL block takes that binary object and creates a URL. Finally, the URL is bound to the URL property of an image component. Result: The user drags an image from their file system and drops it on the shape. Then, the user sees the image on the page. |
