Color Management System, calibrator and profiler

Argyll is an experimental, open source, ICC compatible color management system. It supports accurate ICC profile creation for scanners, CMYK printers, 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 the fastest portable 8 bit raster color conversion engine available anywhere, as well as support for fast, fully accurate 16 bit conversion. Device color gamuts can also be viewed and compared using a VRML viewer.

optipng

advanced PNG (Portable Network Graphics) optimizer

OptiPNG is a PNG optimizer that recompresses the image files to a smaller size. It losslessly reduces the bit depth, the color type and the color palette of the image, runs a suite of compression methods and strategies, and selects the compression parameters that yield the smallest output file. It also recognizes several external file formats like BMP, GIF, TIFF and PNM (PBM, PGM, PPM).

secure, reliable, lean, and easy-to configure SMTP server

opensmtpd

secure, reliable, lean, and easy-to configure SMTP server

The OpenSMTPD server seeks to be * as secure as possible, and uses privilege separation to mitigate possible security bugs * as reliable as possible: any accepted email must not be lost * lean: it covers typical usage cases instead of every obscure one * easy to configure, with a configuration syntax reminiscent of the OpenBSD Packet Filter's (PF) * fast and efficient: it can handle large queues with reasonable performance
