Method, system and apparatus for rendering a map according to texture masks

A system, comprising:

• a memory;
• and
• one or more processors coupled to the memory, wherein the memory comprises program instructions configured to implement a map application executable by the one or more processors to:
• obtain from a server map data, wherein said map data comprises vector graphics data describing one or more shapes for a map, wherein said map data further comprises a mask indicator for one or more of the one or more shapes;
• render a map view based on the obtained map data for display on the system comprising:
• for each respective mask indicator from the map data for the map view, create one or more mask shapes each corresponding to a shape described by the vector graphics data;
• for each created mask shape:
• compare the mask indicator to a previously obtained mask index at the system, wherein said mask index comprises one or more mask indicators, and wherein the one or more mask indicators of the mask index are linked to a texture source;
• identify the texture source linked to the mask indicator of the mask index that matches the mask indicator for the mask shape according the comparison;
• obtain a texture for the mask shape from the texture source;
• and
• apply the mask shape to the obtained texture to render a fill portion of the corresponding shape described by the vector graphics data.

A non-transitory, computer-readable storage medium, storing program instructions, wherein the program instructions are computer-executable to implement a map application configured to implement:

• obtaining from a server map data, wherein said map data comprises vector graphics data describing one or more shapes for a map, wherein said map data further comprises a mask indicator for one or more of the one or more shapes;
• rendering a map view based on the obtained map data for display comprising:
• for each respective mask indicator from the map data for the map view, creating one or more mask shapes each corresponding to a shape described by the vector graphics data;
• for each created mask shape:
• comparing the mask indicator to a previously obtained mask index, wherein said mask index comprises one or more mask indicators, and wherein the one or more mask indicators of the mask index are linked to a texture source;
• identifying the texture source linked to the mask indicator of the mask index matching the mask indicator for the mask shape according the comparison;
• obtaining a texture for the mask shape from the texture source;
• and
• applying the mask shape to the obtained texture to render a fill portion of the corresponding shape described by the vector graphics data.

A multi-function device, comprising:

• a touch-sensitive display device;
• one or more processors;
• one or more memories storing a map application executable on the one or more processors to:
• obtain from a server map data, wherein said map data comprises vector graphics data describing one or more shapes for a map, wherein said map data further comprises a mask indicator for one or more of the one or more shapes;
• render a map view based on the obtained map data for display on the multi-function device comprising:
• for each respective mask indicator from the map data for the map view, create one or more mask shapes each corresponding to a shape described by the vector graphics data;
• for each created mask shape:
• compare the mask indicator to a previously obtained mask index stored in the one or more memories, wherein said mask index comprises one or more mask indicators, and wherein the one or more mask indicators of the mask index are linked to a texture source;
• identify the texture source linked to the mask indicator of the mask index matching the mask indicator for the mask shape according the comparison;
• obtain a texture for the mask shape from the texture source;
• apply the mask shape to the obtained texture to render a fill portion of the corresponding shape described by the vector graphics data;
• and
• display the rendered map view on the touch-sensitive display device.

An electronic device, comprising:

• an electronic display;
• and
• a map component, implemented by one or more processors, configured to:
• obtain from a server map data, wherein said map data comprises vector graphics data describing one or more shapes for a map, wherein said map data further comprises a mask indicator for one or more of the one or more shapes;
• render a map view based on the obtained map data for display on the electronic display comprising:
• for each respective mask indicator from the map data for the map view, create one or more mask shapes each corresponding to a shape described by the vector graphics data;
• for each created mask shape:
• compare the mask indicator to a previously obtained mask index at the electronic device, wherein said mask index comprises one or more mask indicators, and wherein the one or more mask indicators of the mask index are linked to a texture source;
• identify the texture source linked to the mask indicator of the mask index matching the mask indicator for the mask shape according the comparison;
• obtain a texture for the mask shape from the texture source;
• apply the mask shape to the obtained texture to render a fill portion of the corresponding shape described by the vector graphics data;
• and
• initiate display of the rendered map view on the electronic display.
