類型別名 ImageLoadFunctionType

A function that takes an ol.Image for the image and a {string} for the src as arguments. It is supposed to make it so the underlying image ol.Image#getImage is assigned the content specified by the src. If not specified, the default is

function(image, src) {
  image.getImage().src = src;
}

Providing a custom imageLoadFunction can be useful to load images with post requests or - in general - through XHR requests, where the src of the image element would be set to a data URI when the content is loaded.
