LASi is a library written by Larry Siden that provides a C++ stream output interface ( with operator << ) for creating Postscript documents that can contain characters from any of the scripts and symbol blocks supported in Unicode and by Owen Taylor's Pango layout engine. The library accommodates right-to-left scripts such as Arabic and Hebrew as easily as left-to-right scripts. Indic and Indic-derived Complex Text Layout (CTL) scripts, such as Devanagari, Thai, Lao, and Tibetan are supported to the extent provided by Pango and by the OpenType fonts installed on your system. All of this is provided without need for any special configuration or layout calculation on the programmer's part. Although the capability to produce Unicode-based multilingual Postscript documents exists in large Open Source application framework libraries such as GTK+, QT, and KDE, LASi was designed for projects which require the ability to produce Postscript independent of any one application framework.
LATEX2HTML is a converter written in Perl that converts LATEX documents to HTML. This way e.g. scientific papers - primarily typeset for printing - can be put on the Web for online viewing. LATEX2HTML does also a good job in rapid web site deployment. These pages are generated from a single LATEX source.
Lato is a sanserif typeface family designed in the Summer 2010 by Warsaw-based designer Łukasz Dziedzic ("Lato" means "Summer" in Polish). In December 2010 the Lato family was published under the open-source Open Font License by his foundry tyPoland, with support from Google. When working on Lato, Łukasz tried to carefully balance some potentially conflicting priorities. He wanted to create a typeface that would seem quite "transparent" when used in body text but would display some original treats when used in larger sizes. He used classical proportions (particularly visible in the uppercase) to give the letterforms familiar harmony and elegance. At the same time, he created a sleek sanserif look, which makes evident the fact that Lato was designed in 2010 - even though it does not follow any current trend. The semi-rounded details of the letters give Lato a feeling of warmth, while the strong structure provides stability and seriousness. "Male and female, serious but friendly. With the feeling of the Summer," says Łukasz. Lato consists of nine weights (plus corresponding italics), including a beautiful hairline style. It covers 2300+ glyphs per style and supports 100+ Latin-based languages, 50+ Cyrillic-based languages as well as Greek and IPA phonetics.
LittleCMS intends to be a small-footprint, speed optimized color management engine in open source form. LCMS2 is the current version of LCMS, and can be parallel installed with the original (deprecated) lcms.
The library supports many operations that are useful on * Document images * Natural images Fundamental image processing and image analysis operations * Rasterop (aka bitblt) * Affine transforms (scaling, translation, rotation, shear) on images of arbitrary pixel depth * Projective and bi-linear transforms * Binary and gray scale morphology, rank order filters, and convolution * Seed-fill and connected components * Image transformations with changes in pixel depth, both at the same scale and with scale change * Pixelwise masking, blending, enhancement, arithmetic ops, etc.
The less utility is a text file browser that resembles more, but has more capabilities. Less allows you to move backwards in the file as well as forwards. Since less doesn't have to read the entire input file before it starts, less starts up more quickly than text editors (for example, vi). You should install less because it is a basic utility for viewing text files, and you'll use it frequently.
LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values.
libEMF is a library for generating Enhanced Metafiles on systems which don't natively support the ECMA-234 Graphics Device Interface (GDI). The library is intended to be used as a driver for other graphics programs such as Grace or gnuplot. Therefore, it implements a very limited subset of the GDI.
