It's a premultiplied image. This implies that we were misusing encodePNG
in most cases, as we were passing premultiplied pixels which were then
interpreted as unmultiplied. I changed encodePNG to accept premultipled
pixels, and unpremultiply in the implementations.
ConstrainMode gives flexibility to our engine to choose between
constraining both vertically and horizontally, or just vertically
(default behavior).
Constrain in both axis means we can no longer pan the map beyond the map
boundaries. This fixes an issue where e.g. annotations disappear upon
crossing the map boundaries.
MapData was needed for two things: getting the default transition and
fade durations, and detecting still rendering vs. continuous.
The first is avoided by making transition durations optional, and
supplying the default fallback value at evaluation time. The second did
not fix the still rendering issue, and will be followed up with a
different approach in a later commit.
Adding new mbgl::GLContextMode enum to mbgl::Map ctor, which gets stored
in MapData. In shared GL context environments, we cannot assume that the
GL state that has been left since the last draw is the same, so we reset
the GL configurations to their default values.
- does not prepend /v4/ to api endpoints like /fonts/v1/
- only prepends it to things starting with /fontstack
- solves the problem in #1918
- refs mapbox/mapbox-gl-style-spec#309
Relevant changes:
- Added 'defaultFadeDuration' and 'defaultTransitionDelay' to MapData;
- Painter & StyleParser now receives a reference to MapData;
- As previously seen on the code: 300ms is the default fade duration
and 0ms is the default transition duration;
- We no longer pass the current time point to Style, since it now uses
MapData.animationTime, which gets updated in MapContext::update().
- Updated StyleParser check to use a mock MapData;
Instead of transforming between return value and callback, pass
the wrapped callback on to the invoked function as the last argument.
This eliminates the need for multiple invokeWithArgument overloads
and permits invoked functions to be asynchronous.
mbgl::Thread will keep a ThreadContext for each running instance
in a thread_local so we don't need to lookup a man in the Environment
every time we need some info about the current thread.
This patch is moving the ::currentlyOn check used on Debug build from
the Environment class to the ThreadContext.
The util::Thread will call the stop() method of the MapContext's RunLoop
which will wait for the pending tasks tied to it to complete.
If we have a request that is timeout'ing, this could mean a really long
wait. Instead, we now send a cleanup message that will reset all the
attributes first (canceling the pending requests) so the the MapContext
gets destructed quickly.
