The Link Grammar Parser (link-grammar) is a syntactic parser of English, Russian, Arabic, and Persian (and other languages as well), based on link grammar, an original theory of English syntax. Given a sentence, the system assigns to it a syntactic structure, which consists of a set of labelled links connecting pairs of words. The parser also produces a "constituent" (Penn tree-bank style phrase tree) representation of a sentence (showing noun phrases, verb phrases, etc.). The RelEx extension provides dependency-parse output.
Apitron PDF Rasterizer is a .NET component that performs high-quality conversion from PDF files to images. It supports complex PDF content including text (with embedded, externally linked, standard, simple, and composite fonts), images, including masked ones, complex paths and fills, PDF Forms, annotation objects of various types, all blending modes, tiling patterns, shading patterns (function-based, axial, radial), transparency groups, masked content (stencil masks, colorkey masks, soft masks), all colorspaces specified by the PDF standard, Adobe Illustrator created files, PDF bookmarks and page navigation support, and text search and highlighting (including non-Latin alphabets).
twyg lets you visualise arbitrary tree structures in a pretty way. The appearance of the tree (layout, color, node, connection shapes, etc.) is fully controlled via configuration files in a generative way. This means that almost all visual properties of the output can be controlled by expressions that depend on the characteristics of the tree (e.g. the color or shape of a node can be a function of its hierarchical position in the tree). This allows for crafting very flexible configurations that can be applied to trees of arbitrary size and complexity. It supports the Cairo and NodeBox1 rendering backends.
f265 is a cross-platform HEVC/H.265 video encoder. The project initially targets high quality offline encoding, but it is not limited to this scope. It is designed from the ground up to maximize quality and performance in offline and real-time scenarios using recent hardware technology and interfaces such as the Intel® AVX2 instruction set.
etmTk is an event and task manager. In contrast to most calendar/todo applications, creating items (events, tasks, and so forth) in etm does not require filling out fields in a form. Instead, items are created as free-form text entries using a simple, intuitive format and stored in plain text files. Both a graphical user interface based on Tkinter and a command line interface are provided.
