AGSLineSymbol Class Reference

Description

An abstract base class for line symbols.

Subclasses represent line symbols. Symbols describe how graphics and features look on a map. Different symbols are used with different geometry types. Line symbols are used to display graphics and features which are based on polyline geometries.

Method Documentation

createSwatchWithBackgroundColor:screen:completion:

- (id<AGSCancelable>) createSwatchWithBackgroundColor:		(nullable AGSColor *)	backgroundColor
screen:		(nullable AGSScreen *)	screen
completion:		(void(^)(AGSImage *__nullable swatch, NSError *__nullable error))	completion

Creates swatch with provided background color.

Parameters

backgroundColor	Desired background color of the image.
screen	Screen that the swatch will be rendered for. If you specify nil then the main screen will be used.
completion	A block that is invoked when the operation completes.

createSwatchWithCompletion:

- (id<AGSCancelable>) createSwatchWithCompletion:

(void(^)(AGSImage *__nullable swatch, NSError *__nullable error))

completion

Creates a swatch with a clear background color. This method uses main screen's scale to determine the size of the image.

Parameters

completion

block that is invoked when operation completes.

createSwatchWithGeometry:width:height:screen:backgroundColor:completion:

- (id<AGSCancelable>) createSwatchWithGeometry:		(AGSGeometry *)	geometry
width:		(NSInteger)	width
height:		(NSInteger)	height
screen:		(nullable AGSScreen *)	screen
backgroundColor:		(nullable AGSColor *)	backgroundColor
completion:		(void(^)(AGSImage *__nullable swatch, NSError *__nullable error))	completion

Creates a swatch using the provided geometry and other parameters. This is the most configurable of the methods to create swatches. You can pass the pixels per inch that you would like the image to be rendered at. This will determine how many pixels are used to render symbols of sizes that are specified in points.

Parameters

geometry	The geometry of the symbol to be drawn in the swatch image. The specified geometry is in DIPs, with the point {0,0} located at the center of the swatch image. The X-axis increases towards the right side of the swatch image. The Y-axis increases towards the top of the swatch image. For example: when creating a swatch for an AGSMarkerSymbol, specifying a geometry of {10,10} will draw the marker 10 DIPs up and to the right of the center of the swatch. The geometry type (AGSPoint, AGSPolyline, AGSPolygon) should correspond to the symbol type (AGSMarkerSymbol, AGSLineSymbol, AGSFillSymbol). The geometry's spatial reference is ignored.
width	Desired width of the image in pixels.
height	Desired height of the image in pixels.
screen	The screen that the swatch will be rendered for. If you specify nil then the main screen will be used.
backgroundColor	The desired background color of the image.
completion	A block that is invoked when operation completes.

fromJSON:error:

+ (nullable id<AGSJSONSerializable>) fromJSON: (id)  JSONObject error: (NSError **)  error

staticrequiredinherited

Initializes and returns an object from its JSON representation.

Parameters

JSONObject	NSDictionary or NSArray containing the JSON.
error	encountered during the operation, if any.

isEqualToSymbol:

- (BOOL) isEqualToSymbol:

(AGSSymbol *)

other

Compares this symbol to another for equality.

Parameters

other

The other symbol to compare this one to.

Returns

YES if the two symbols are equal, otherwise NO.

toJSON:

- (nullable id) toJSON: (NSError **)  error

requiredinherited

Returns JSON representation for this object.

Parameters

error

encountered during the operation, if any.

Returns

NSDictionary or NSArray containing the JSON.

Reimplemented in AGSPortalItem.

Property Documentation

antialias

- (BOOL) antialias

readwritenonatomicassign

Whether the line should be anti-aliased. Defaults to true.

color

- (AGSColor*) color

readwritenonatomicstrong

The color for the line symbol.

When getting the color (or tint color) from a symbol, the consensus value (for all layers) is reported. If there is no consensus (one or more layers have different colors), a nil value is reported for the color. Likewise, setting a value for color on a symbol will apply that color to all layers the symbol contains.

If you don't want changes to the symbol color to propagate to some of the symbol layers it contains, you can lock the color (or tint color) for those layers. If a symbol layer is color-locked, changes to the parent symbol will not affect the symbol layer. This also means that the layer will not be considered when determining a consensus color for the symbol as a whole.

unknownJSON

- (NSDictionary<NSString*,id>*) unknownJSON

readrequirednonatomiccopyinherited

A dictionary of values that was in the source JSON but was unparsed by API.

Returns

NSDictionary containing the unknown JSON.

Since

100

unsupportedJSON

- (NSDictionary<NSString*,id>*) unsupportedJSON

readnonatomiccopyinherited

A dictionary of values that are supported by the REST API, but not exposed through the SDK API.

Returns

NSDictionary containing the unsupported JSON.

width

- (CGFloat) width

readwritenonatomicassign

Width of the line, in points (not pixels)
