Release notes

27.07.2015

Version: 3.2.0 RC0

GIT commit: 56962750201c5dfa7c6765e7ea5ce75fdbc2b8dc

New features

In all versions

• Automatic point/marker clustering using ClusteredVectorLayer
• Multigeometry support. Geometry package contains now MultiGeometry, MultiPoint, etc classes. A GeometryCollection vector element must be used together with these new geometry types.
• GeoJSON parser and generator. Only files that contain geometry objects are supported, features are not supported as there is not direct mapping to SDK objects.
• Implemented basic CartoCSS style parsing. Only style attributes (like line-width, marker-size, etc) are supported, full CartoCSS support with selectors is planned at later stage.

In GIS Extension (Enterprise version)

• Custom projections are now supported when using GDAL/OGR layers
• Vector editing support using EditableVectorLayer class
• Implemented WKB/WKT reading and writing
• More complete support for OGR: layers and layer fields can be created and deleted. Previously only modifying was supported.

Changes, minor updates

• Added additional constructor to NutiteqOnlineVectorTileLayer that takes tile source id as a parameter
• Added getDataExtent method to LocalVectorDataSource
• Added getDataExtent method to MBTilesTileDataSource
• Added getDataExtent method to BitmapOverlayRasterTileDataSource
• Implemented getOpacity/setOpacity methods for RasterTileLayer
• Added getLayer method to VectorElementClickInfo class
• Added getDataSource method to NMLModelLODTreeLayer
• Added special error code to PackageErrorType: PACKAGEERRORTYPENOOFFLINE_PLAN, used when license does not allow using Nutiteq offline package service
• Added support for PNGs with explicit SRS info in GDALRasterTileDataSource (Enterprise edition)
• Tile preloading algorithm is changed, new algorithm should give more predictable results with less tile flickering for both vector and raster tiles
• Tile preloading is better integrated now with vector tile renderer, resulting in better performance and less tile fading effects
• Implemented better view envelope calculation, resulting in better performance in some VectorDataSource implementations
• Added 2 static methods to BitmapUtils class: loadBitmapFromAssets and loadBitmapFromFile
• Relaxed Android OpenGL renderer requirements for older lower end devices, for better compatibility with very old Android devices
• MBVectorTileDecoder class now supports non-gzipped vector tiles and is compatible with MapZen tiles now

API changes

• Bitmap class constructor with asset name argument is deprecated. Instead, BitmapUtils.loadBitmapFromAssets should be used.
• Bitmap class constructor that takes compressed byte vector as an argument is deprecated. Instead, Bitmap.createFromCompressed method (static) should be used.
• LocalSpatialIndexType enum values are changed to conform with SDKs naming conventions. Old names are available as deprecated but will be removed in future versions.
• MapTileQuadTreeNode class is removed from API. This is an internal SDK class that has very limited public use.
• The following methods that were deprecated in Android SDK 3.1 are now removed (NOTE that similar methods with non-capitalized names are available): Log.SetShow*, AssetUtils.LoadBytes, BitmapUtils.CreateBitmapFromAndroidBitmap, BalloonPopupStyleBuilder.set[Left|Right]Bitmap(com.android.Graphics.Bitmap)
• The following methods that were deprecated in iOS SDK 3.1 are now removed (NOTE that similar methods with non-capitalized names are available): Log.SetShow*, AssetUtils.LoadBytes, AssetUtils.Calculate[Resource|Writable]Path, BitmapUtils.CreateBitmapFromUIImage

Fixes

• Fixed object ownership issues in listener callbacks, that could lead to native crashes or data corruption when callback argument reference was stored in member variable
• Fixed issues with object lifecycle management causing native crashes or data corruption in rare cases
• Fixed memory leaks with vector tile layers and NML layers, memory was not freed when layers were removed
• Fixed rare threading dead-locks when SDK methods were used from listener callbacks
• Fixed memory leaks in iOS SDK when listener objects were queried
• Fixed type wrapping issues with user derived classes Popup classes and getter-methods
• Fixed memory leak in Android/Xamarin.Android SDK with internal RedrawRequestListener class, resulting activity leaking when closed
• Fixed vector tile line antialiasing on low/very high DPI screens and with some custom display configurations
• Fixed rendering of non-vector-tile patterned lines
• Fixed issues with vector elements offseting when crossing 180th meridian, sometimes resulting in elements being shifted
• Fixed flickering with vector tile offsetting when crossing 180th meridian
• Fixed rendering of lines containing > 64k vertices, such lines were ignored previously
• Fixed TileDataSource.getProjection returing wrong results in iOS SDK
• Fixed issues with click handling in iOS Xamarin component when used in Xamarin.Forms
• Fixed issue when vector elements stored in LocalVectorDataSource with KdTree index were updated, but results were not displayed properly
• Fixed Bitmap.compressToInternal not working with non-power-of-two bitmaps
• Fixed MapBounds.contains(MapPos) returning wrong results with some argument values
• Fixed various internal locking-related issues causing deadlocks/ANRs in rare cases
• Fixed handling of open polygons. SDK used to explicitly add a vertex for open polygons, this is no longer the case, original vertex list is preserved.
• Fixed issue with overlapping billboards that were not properly synchronized when updated
