ST_Pixelize drawing polygon perimeter rather than all pixels in polygon about sedona HOT 3 OPEN

suspect problems is :
https://github.com/apache/sedona/blob/master/spark/common/src/main/scala/org/apache/spark/sql/sedona_viz/expressions/Pixelize.scala
lines53-55
case geometry: Polygon => {
RasterizationUtils.FindPixelCoordinates(resolutionX, resolutionY, boundary, inputGeometry.asInstanceOf[Polygon], reverseCoordinate)
}

adding an extra argument to the call of 1.0 calls a different method which gets the interior pxiels ?

from sedona.

Getting the interior pixels needs some sorts of sweep line algorithms to scan the entire geometry. This was not implemented.

Hi,
I think there is already a method that will get all the pixels in a polygon - https://github.com/apache/sedona/blob/master/spark/common/src/main/java/org/apache/sedona/viz/utils/RasterizationUtils.java#L214

public static List<Tuple2<Pixel, Double>> FindPixelCoordinates(int resolutionX, int resolutionY, Envelope datasetBoundary, Polygon spatialObject, boolean reverseSpatialCoordinate, Double objectWeight)

I agree it's not the most efficient !
