I am trying to create a web app that allows the user to load an image from a local folder and process it with some image processing. I was able to do that with FileReference and Loader.
I am using an asynchronous shader to process the image and it seems that when the image is loaded locally the interface is locked out for a second or so before showing the result. However, if the image is embedded this does not happen and the image is updated instantly with the result.
I don't really understand why an image loaded with a loader has this lag and an embadded image does not... Can anyone help?
