[Gnafu (JIRA)]

Title: Message Title

Gnafu created an issue   GeoServer / GEOS-9284 Default RasterSymbolizer style produces different images if JAI-Ext is enabled or not Issue Type: Bug Affects Versions: 2.14.1, 2.15.2, 2.16-RC Assignee: Unassigned Attachments: float32_nodata.tif, it.geosolutions-float32_nodata_bgcolor_JAIEXT.jpg, it.geosolutions-float32_nodata_bgcolor_NO_JAIEXT.jpg, screenshot - annotated.PNG Components: styling, WMS Created: 11/Jul/19 12:49 PM Environment: Tested on Linux with OpenJDK 64-Bit 1.8.0_181 and Window 10 with Java HotSpot(TM) 64-Bit 1.8.0_161 Priority: Medium Reporter: Gnafu The same Geotiff is rendered differently if JAI-Ext is enabled or not. I originally found this in 2.15.x and confirmed it exists on 2.14.1 too. To reproduce: Download the latest 2.16.x platform independent binary Publish the attached float32_nodata.tif file as a simple GeoTiff Use the default "raster" style without any change Preview it (see the attached it.geosolutions-float32_nodata_bgcolor_JAIEXT.jpg) Note: I used the BGCOLOR parameter to see the data boundaries Restart GeoServer with the "-Dorg.geotools.coverage.jaiext.enabled=false" parameter to disable JAIEXT Preview the layer again (see the attached it.geosolutions-float32_nodata_bgcolor_NO_JAIEXT.jpg) See the attached "screenshot - annotated.PNG" file to see how the file looks like in QGIS. I used the purple background color to see the difference between the nodata area an the maximum value area. The images are different: With JAI-Ext the full extent is black Without JAI-Ext the nodata is black and the rest is white The sample file has the following content : Total pixel count: 100 NODATA pixel count: 25 Value Pixel count 1 33 1.05 25 1.1 8 1.3 9 Add Comment   Get Jira notifications on your phone!
