I have GeoTIFF file (int16), and I publish the layer in Geoserver using like store in Geoserver my file, now I used WCS request builder to get JPEG-like output format and I get an error "No possible show the image because have errors". But If I convert my GeoTIFF file from Int16 to Byte, and I publish another layer in Geoserver with it I don't have any problem and I get JPEG in WCS, but in this case I get GeoTIFF (byte) too.
So, I want to get GeoTIFF (int16) and JPEG file by WCS service, so what kind of GeoTIFF I need like source? Or maybe I need any extension to get this?
This is my system: - Ubuntu 14. - apache-tomcat-8.5.32_2 - jdk1.8.0_181 - Geoserver 2.13.2 - native JAI and ImageIO extensions
