SANE stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware (flatbed scanner, handheld scanner, video and still cameras, framegrabbers, etc.). The SANE standard is public domain and its discussion and development are open to everybody. The source code is written for UNIX (including Linux) and is available under the GPL, but commercial applications and backends are welcome. The package contains the libraries, net support, and scanimage. The X frontends xscanimage and xcam can be found in sane-frontends.
Argyll is an ICC compatible color management system. It supports accurate ICC profile creation for scanners, CMYK printers, and film recorders, and calibration and profiling of displays. Spectral sample data is supported, allowing a selection of illuminants observer types, and paper fluorescent whitener additive compensation. Profiles can also incorporate source specific gamut mappings for perceptual and saturation intents. Gamut mapping and profile linking uses the CIECAM02 appearance model, a unique gamut mapping algorithm, and a wide selection of rendering intents. It also includes code for a fast 8-bit raster color conversion engine as well as support for fast, fully accurate 16-bit conversion. Device color gamuts can also be viewed and compared using a VRML viewer.
Imagero is a Java imaging library. Supported file types include BMP, GIF, TIFF, PNG, JNG, MNG, JPEG (including CMYK and 12-bit grey), PSD, PBM, PGM, PPM, TGA, EPS, EPSI, EPSF, AI, PDF, MRW, CRW, NEF, DCR, and DNG. Imagero can read thumbnails and can read and write metadata (IPTC, EXIF, XMP, Wang Annotations, Image Resource Blocks, Image File Directrories, JPEG Markers). Accurate color conversion is done with ICC profiles. TIFF tools allow you to split and merge TIFF images, add and remove IFDs. Lossless JPEG to TIFF and TIFF to JPEG conversion can be done. Lossless JPEG operations are supported.
Inkscape is a drawing tool with capabilities similar to Illustrator, Freehand, and CorelDraw that uses the W3C standard scalable vector graphics format (SVG). The supported SVG features include basic shapes, paths, text, markers, clones, alpha blending, transforms, gradients, and grouping. In addition, it supports Creative Commons meta-data, node-editing, layers, complex path operations, text-on-path, and SVG XML editing. It also imports several formats like EPS, Postscript, JPEG, PNG, BMP, and TIFF and exports PNG as well as multiple vector-based formats.
Sketsa SVG Editor is a vector drawing application based on SVG. It allows users to create vector graphics that can be scaled and printed at any resolution, without losing detail or clarity. It features various tools for optimizing content creation, and includes a property palette, a DOM editor, a source editor, a resource editor, SVG-specific shape tools, transformation tools, and additional illustration tools. It uses SVG as its native file format.
