Reproject static image: updating source transforms the image again
Got stuck.......I'm loading png images onto OpenStreetMap as a static image layer. When I reproject the map from e.g. 3857 to 32661 the image is also reprojected automatically (which I wanted), but when I update the source of the static image the image layer is transformed again. The transformed image has again a rectangle shape like the original one......frustrating....
How can I get the image to not transform again, but just show the updated source (that has the same dimensions as the original one, but transformed according to the new projection).
I have an imagelayer "IMG_LYR" with source "IMG_LYRStaticSource":
IMG_LYRbounds = [45.3, 30.9, -14.6, 72.6]; // LON/LAT
url = "http://localhost/img/myupdatedimg.png";
IMG_LYR = new ol.layer.Image({
source: IMG_LYRStaticSource
});
IMG_LYRStaticSource = new ol.source.ImageStatic({
url: url,
projection: map.getView().getProjection().getCode(),
imageExtent: ol.extent.applyTransform(IMG_LYRbounds, ol.proj.getTransform("EPSG:4326", map.getView().getProjection().getCode()))
});
When I show the 'projection' in the inspect-console it's confirmed that it is "32661". What am I doing wrong??
Btw: I use also Proj4 defs! That that works is confirmed when the original image and the underlying map transforms when the new projection 32661 is set.

Only your view projection is changing, the projection of the static image doesn't change, just like OSM it will be reprojected by the view.
IMG_LYRStaticSource = new ol.source.ImageStatic({
url: url,
projection: "EPSG:3857",
imageExtent: ol.extent.applyTransform(IMG_LYRbounds, ol.proj.getTransform("EPSG:4326", "EPSG:3857")
});
