jiayuasu opened a new issue, #3245:
URL: https://github.com/apache/sedona/issues/3245
## Expected behavior
`RS_AsCOG` should encode rasters of any size and band data type, or fail
with a clear message about unsupported inputs.
## Actual behavior
Encoding a **1024×1024 raster with a byte band** throws:
```
org.apache.spark.sql.sedona_sql.expressions.InferredExpressionException:
Exception occurred while evaluating expression RS_AsCOG ...
Caused by: java.lang.ArrayIndexOutOfBoundsException
at java.base/java.util.zip.Deflater.setInput(Deflater.java:242)
at
it.geosolutions.imageio.compression.zipdeflate.ZipDeflateCompressor.compress(ZipDeflateCompressor.java:58)
at
it.geosolutions.imageioimpl.plugins.tiff.TIFFDeflater.encode(TIFFDeflater.java:164)
at
it.geosolutions.imageioimpl.plugins.tiff.TIFFImageWriter.writeTile(TIFFImageWriter.java:1912)
```
The failure is specific to that size/type combination. Probe matrix (each
cell is `RS_AsCOG(RS_MakeEmptyRaster(1, '<type>', <size>, <size>, 10.0, 52.0,
0.001, -0.001, 0, 0, 4326))`):
| size | 'B' (byte) | 'I' (int) | 'D' (double) |
|------|------------|-----------|--------------|
| 256 | OK | OK | OK |
| 512 | OK | OK | OK |
| 768 | OK | OK | OK |
| 1024 | **ArrayIndexOutOfBoundsException** | OK | OK |
`RS_AsGeoTiff` on the same 1024×1024 byte raster works fine; only the COG
path fails, which suggests the tiled/Deflate encode path in the geosolutions
TIFF writer receives a mis-sized buffer for single-byte samples at this
dimension.
## Steps to reproduce the problem
```sql
SELECT RS_AsCOG(RS_MakeEmptyRaster(1, 'B', 1024, 1024, 10.0, 52.0, 0.001,
-0.001, 0, 0, 4326));
-- ArrayIndexOutOfBoundsException at java.util.zip.Deflater.setInput
```
Any 1024×1024 single-band byte raster reproduces it; found while generating
sample GeoTIFF fleets with the raster writer.
## Settings

Apache Flink version = N/A
API type = Python (SQL expression; the failure is in the JVM encode path)
Scala version = 2.12
