GraphicFill loading state when writing style #434

Open KaiVolland opened 2 years ago

KaiVolland commented 2 years ago

As stated by @nevaldas the loading state of images can be a problem when writing GraphicFill styleFunctions with external graphics: https://github.com/geostyler/geostyler-openlayers-parser/pull/388#issuecomment-93328645

Possible solutions could be:

Wait for the images to be loaded before returning the style. This could be difficult when using placeholders in the image url.
optionaly passing the olmap and add an onload listener to rerender it
…

Please discuss and add more ideas. :)

Also we could provide some kind of event, so the actual application can decide when to trigger the rerender. However, all applications would have to implement this then.
