- Don't rasterize glyphs if font does not support requested code point
- Render symbols at hardcoded baseline, so that locally rasterized glyphs
align better with server side generated fonts.
- Resize backing QImage width to be at least 24px
Binary shader support has been removed in commit c2f974f2a5 ([core]
Remove binary shader support). This left-over parameter is not used
anywhere anymore.
- Do not carry it over everywhere as parameter, it is a shared
instance anyway and the lifecycle is pretty much the app lifecycle
from the moment we instantiate a map.
- Rename to BackgroundScheduler because it is a Scheduler that will
do tasks in the background, we don't make assumptions if it is a
thread pool or a single thread.
- Most importantly, remove the dependency from `core` on `platform`.
Group bounds, minimum and maximum zoom related methods together using
the new BoundOptions.
v2: Document that getBounds() initializes all optional fields.
- Add test for getBounds() on a map with default values.
Using different exception pointers to specify the loading failure makes
an awkward API. Most users rethrow the exception only to figure out what
type of error happened so it can be reported properly. So replace the
exception pointer with a enum an string description of the failure.
`QColor::name()` produces `#rrggbb` format where alpha is missing.
Use `rgba(...)` string instead when convert `QColor` to mapbox style.
Note: `QColor::name(QColor::HexArgb)` produces `#aarrggbb` format string,
but mapbox does not support this format apparently.
These loaders will provide pointers to the platform implementation
of OpenGL. On Android, Linux and Darwin, we simply link with the
OpenGL implementation that is expected to exist on the platform.
Qt has its own GL loader, so we just connect the dots.
There are 3 methods in QMapboxGL which can be static method.
QMapboxGL::metersPerPixelAtLatitude
QMapboxGL::projectedMetersForCoordinate
QMapboxGL::coordinateForProjectedMeters
Add these functions into QMapbox namespace as global functions.
The methods in QMapboxGL are kept for backward compatibility.
When opening many maps and sharing the same filesource:
- Say we open around 30 maps and they all have the same style.
- They will all request the same sprite.json, but Qt filesource will
restrict simultaneous request to 20.
- Mapbox GL will send some sprite.json to the filesource and queue
some internally along with other requests.
- When the first sprite.json arrives and the Qt filesource calls the
callback, Mapbox GL will synchronously push queued requests to the
Qt filesource when a request is handled.
- We are walking a QVector dispatching sprite.json requests, but more
requests get added to this QVector while we are walking it using an
iterator.
- That corrupts the iterator and we get a crash.
The fix is simple, just pop items from the QVector until it is empty
instead of using iterators.
The `style::Layer` class now exposes all the properties contained at `style::LayerImpl`.
This allowed to drop `style::Layer::accept()` method usage, avoid the repeated generated code
and thus save some binary size.
This patch is a part of the layers modularization effort.
