Overlay Patterns on android google map

Patterner is an android library, that draws line patterns on google map programmatically, it supports irregular shaped-polygons.

How to use

Add dependency to the Gradle:

  implementation 'com.github.AmosKorir:Patterner-googlemap-patterns:Tag'

Example usage of the MapPatterner

 //overlay
 val groundOverlay = GMapPattern.getBitmapPolygonGround(
            this,
            polygonOptions,
            500,
            500,
            R.drawable.example_pattern
        )

   map.addGroundOverlay(groundOverlay)

getBitmapPolygonGround returns a shaped-bitmap image ovelay of the polygon supplied.

 /**
 * @param context , this is the view context, it required for creating bitmap
 * @param polygonOptions, this provide list of latLongs that forms the polygon
 * @param width , Integer width of the required pattern
 * @param height , Integer width of the required pattern
 * @param drawable image resource ID
 * @return Ground Overlay
 */

fun getBitmapPolygonGround(
 context: Context,
 polygonOptions: PolygonOptions,
 width: Int,
 height: Int,
 drawable: Int
): GroundOverlayOptions

drawPolygonBitmap returns a shaped-bitmap of the polygon supplied.

	/**
   * @param context , this is the view context, it required for creating bitmap
   * @param polygonOptions, this provide list of latLongs that forms the polygon
   * @param width , Integer width of the required pattern
   * @param height , Integer width of the required pattern
   * @param drawable image resource ID
   * @return Bitmap
   */
  fun drawPolygonBitmap(
   context: Context,
   polygonOptions: PolygonOptions,
   width: Int,
   height: Int,
   drawable: Int
  ): Bitmap

To run this example you need to set your map api key in local.properties file

add below line and change the value to your api key

api_map_key="AIzaSyCz75O....."
