ricg72 opened a new issue, #1273:
URL: https://github.com/apache/sedona/issues/1273
## Expected behavior
drawing 10 x 10 polygon expect 100 pixels
```
+---------------------------------------+--------+-----+------------+--------------+
|geo
|size(px)|Is4_4|st_area(geo)|st_length(geo)|
+---------------------------------------+--------+-----+------------+--------------+
|POLYGON ((1 1, 11 1, 11 11, 1 11, 1 1))|100 |true |100.0 |40.0
|
+---------------------------------------+--------+-----+------------+--------------+
```
## Actual behavior
drawing 10 x 10 polygon only getting 40, on the boundary
output - size(px) is wrong
```
+---------------------------------------+--------+-----+------------+--------------+
|geo
|size(px)|Is4_4|st_area(geo)|st_length(geo)|
+---------------------------------------+--------+-----+------------+--------------+
|POLYGON ((1 1, 11 1, 11 11, 1 11, 1 1))|36 |true |100.0 |40.0
|
+---------------------------------------+--------+-----+------------+--------------+
```
## Steps to reproduce the problem
```
case class A(g : String)
val a0 = 1.0
val a1 = 11.0
val d = Seq( A(s"POLYGON (($a0 $a0, $a1 $a0, $a1 $a1, $a0 $a1, $a0 $a0))"))
import spark.implicits._
val df = d.toDS().toDF()
val df2 = df
.withColumn("geo", expr("ST_GeomFromWKT(g)"))
.withColumn("Is4_4", expr("ST_Contains(geo, ST_Point(4,4))")) // should be
in
.withColumn("px", expr("ST_Pixelize(geo, 10,10,
ST_PolygonFromEnvelope(0,0,12,12))")) // make sure (a0,a0) to (a1,a1)
println( s"Number of pixels: ${df2.select( explode(col("px")) ).count()} -
would expect ${(a1-a0) * (a1-a0)} ")
df2.select( col("geo"), size(col("px")), col("Is4_4"), expr("ST_Area(geo)"),
expr("ST_Length(geo)")).show(false)
df2 .select( explode(col("px")) ) .show(false)
```
