libethumb-dev 1.8.6-2.5build1 (arm64 binary) in ubuntu cosmic

 Ethumb uses Evas to generate thumbnail images of given files. The API allows
 great customization of the generated files and also helps complying to
 FreeDesktop.Org Thumbnail Specification
 .
 Ethumb-Client creates thumbnails by communicating with a thumbnail generation
 server using standard D-Bus protocol. The server uses Ethumb itself to
 generate the thumbnail images and cache them using FreeDesktop.Org standard.
 .
 This package contains headers and static libraries for the Ethumb and
 Ethumb-Client libraries.
