See the white table of the attached example images. The quality of the output format is already set to 100. |

One can now configure a Resizer in all implementations of AbstractCropAndResize - 3 implementations are provided, see the info.magnolia.imaging.operations.cropresize.resizers package. |

Did anybody look at GraphicsMagick? "GraphicsMagick is a robust collection of tools and libraries which support reading, writing, and manipulating an image in over 90 major formats including popular formats like TIFF, JPEG, JPEG-2000,PNG, PDF, PhotoCD, SVG, and GIF. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. C, C++, Perl, Tcl, and Ruby are supported. Originally based on ImageMagick, GraphicsMagick focuses on performance, minimizing bugs, and providing stable APIs and ABIs. It runs on all modern variants of Unix, Windows, and Mac OS X." I am not sure how access from java is possible, but otherwise this looks rock solid. It is used e.g. for Flickr |

Much like ImageMagick, it's a native library; unlike ImageMagick, it doesn't seem to have a Java API.
IF there's ever a request for quality so pressing that shows unilaterally that using such a library would give unilaterally better results from either or both the quality or the performance point of view, it'll still be possible to investigate further |
