In Leaflet 0.7 it was null. In our R code, the default was NULL, which we pass to the Leaflet code. Therefore, in Leaflet 1.x we actually override the default zIndex of 1 and change it to "auto". However, for addRaster, we've never allowed the zIndex to be set, so we don't override the new default zIndex of 1. So we end up with a tile layer with zIndex "auto" and a grid layer with a zIndex of 1. For "stacking context" reasons that I do not understand, auto always renders in front of non-auto. Setting the default for tiles to 1 fixes the problem. --- R/layers.R | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/R/layers.R b/R/layers.R index c00dded0f..f384a378b 100644 --- a/R/layers.R +++ b/R/layers.R @@ -306,7 +306,7 @@ tileOptions <- function( zoomOffset = 0, zoomReverse = FALSE, opacity = 1.0, - zIndex = NULL, + zIndex = 1, unloadInvisibleTiles = NULL, updateWhenIdle = NULL, detectRetina = FALSE, From bb4e33d5efaa98f23b2b520c14da9adff6b96763 Mon Sep 17 00:00:00 2001 From: Joe Cheng Date: Fri, 18 Aug 2017 15:25:30 -0400 Subject: [PATCH 41/64] Fix issue with rasters disappearing The getImageData(callback) function as previously written would invoke the callback immediately if image data was already loaded, or asynchronously if image data was not. (I knew this was weird so I noted this in the function's comment.) This turns out to be a problem with Leaflet 1.x because it expects createTile's callback (done) function to only be invoked after createTile has returned. If done is called too soon, then it's ignored, because done first checks the GridLayer's tile cache to see if the tile that's done is even still wanted. Since createTile hasn't returned the tile isn't in the cache yet, and done becomes a no-op. --- inst/htmlwidgets/leaflet.js | 17 +++++++++++++---- javascript/src/methods.js | 17 +++++++++++++---- 2 files changed, 26 insertions(+), 8 deletions(-) diff --git a/inst/htmlwidgets/leaflet.js b/inst/htmlwidgets/leaflet.js index a5b9f3cd1..9a6ab4085 100644 --- a/inst/htmlwidgets/leaflet.js +++ b/inst/htmlwidgets/leaflet.js @@ -2059,11 +2059,15 @@ methods.addRasterImage = function (uri, bounds, opacity, attribution, layerId, g var imgDataCallbacks = []; // Consumers of imgData, w, and h can call this to be notified when data - // is available.
