[MacPorts] #22531: libdevil scaling filters do not work when reducing images
#22531: libdevil scaling filters do not work when reducing images ------------------------------+--------------------------------------------- Reporter: jrmair@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 1.8.1 Keywords: | Port: libdevil ------------------------------+--------------------------------------------- Hi, The following code should generate a high-quality thumbnail (I am using the lanczos3 filter): http://gist.github.com/234637 However, the resulting thumbnail is of very poor quality, it is almost indistinguishable from the nearest neighbor algorithm. This is particualrly strange behavior because in Debian Linux using the libdevil1c2 / libdevil-dev package the thumbnail quality is very high, as expected. What is the difference between the Debian package and the macports libdevil package such that the filters work in Debian but not on macports? It is very important that the high-quality filters work properly as thumbnailing is a very common application of DevIL. -- Ticket URL: <http://trac.macports.org/ticket/22531> MacPorts <http://www.macports.org/> Ports system for Mac OS
