rayoptics is a Python geometrical optics and image forming optics library. It provides a geometric ray tracing foundation for the analysis of image forming and coherent optical systems. A number of standard geometrical analysis options such as transverse ray and wavefront aberration analysis are provided on this base. Paraxial layout of optical systems is also supported by y-ybar diagrams and graphical editing of paraxial rays in lens layout views. Import of Zemax .zmx and CODEV .seq files is supported. RayOptics can be used in Python scripts, the Python and IPython shells, the Jupyter notebook, and a Qt-based graphical user interface application.

Python package for writing Value Change Dump (VCD) files.

Quart is a Python ASGI web microframework. It is intended to provide the easiest way to use asyncio functionality in a web context, especially with existing Flask apps. This is possible as the Quart API is a superset of the Flask API. Quart aims to be a complete web microframework, as it supports HTTP/1.1, HTTP/2 and websockets. Quart is very extendable and has a number of known extensions and works with many of the Flask extensions.

A Python and C++ implementation of the LZ4 streaming format. Large data streams are split into blocks which are compressed using the very fast LZ4 compression algorithm.

LibRaw is a library for reading RAW files from digital photo cameras (CRW/CR2, NEF, RAF, DNG, MOS, KDC, DCR, etc, virtually all RAW formats are supported).

A chain-able generator for python; inspired by the syntactical sugar of java stream

GFAL (Grid File Access Library) is a C library providing an abstraction layer of the grid storage system complexity. The version 2 of GFAL tries to simplify at the maximum the file operations in a distributed environment. The complexity of the grid is hidden from the client side behind a simple common POSIX API. GFAL2 is able to manage all the common used file access protocols in a grid & cloud environment.

Coverage.py is a tool for measuring code coverage of Python programs. It monitors your program, noting which parts of the code have been executed, then analyzes the source to identify code that could have been executed but was not. Coverage measurement is typically used to gauge the effectiveness of tests. It can show which parts of your code are being exercised by tests, and which are not.

The primary goal of **CoSApp** is to help technical department in the design of complex systems. To do so, the framework allows the simulation of various systems representing the different parts of the final product in a common environment. The consequences are the ability for each subsystem team to carry out design study with a direct feedback of the impact of parameters at the product level. The main features are : - Butterfly effect Coupled your preferred simulation software with CoSApp to get immediate impact on main product variables and iterates to converge on a better design. - Design guidance All systems can share design parameters associated with an acceptable range. You can take advantage of those limited degrees of freedom without fear of breaking your neighbors' work. - Margins & Uncertainties All design parameters have an intrinsic dispersion. Knowing the range of fluctuations is crucial to ensure the robustness of the design. CoSApp handles natively uncertain variables.

Lume-epics is a dedicated API for serving LUME model variables with EPICS.

Python Robust Speckle Tracking (pyrost) is a library for wavefront metrology and sample imaging based on ptychographic speckle tracking algorithm.

X.Org X11 autotools macros required for building the various packages that comprise the X Window System.

The X.Org X11 ICE (Inter-Client Exchange) development package.

The ATK library provides a set of interfaces for adding accessibility support to applications and graphical user interface toolkits. By supporting the ATK interfaces, an application or toolkit can be used with tools such as screen readers, magnifiers, and alternative input devices.

Development library for pixman.

This package includes the libruby, necessary to run Ruby.

The Common UNIX Printing System provides a portable printing layer for UNIX® operating systems. It has been developed by Easy Software Products to promote a standard printing solution for all UNIX vendors and users. CUPS provides the System V and Berkeley command-line interfaces. The cups-libs package provides libraries used by applications to use CUPS natively, without needing the lp/lpr commands.

GLib is the low-level core library that forms the basis for projects such as GTK+ and GNOME. It provides data structure handling for C, portability wrappers, and interfaces for such runtime functionality as an event loop, threads, dynamic loading, and an object system.

The libsepol-devel package contains the libraries and header files needed for developing applications that manipulate binary policies.

The libjpeg-turbo package contains a library of functions for manipulating JPEG images. It also contains simple client programs for accessing the libjpeg functions. It contains cjpeg, djpeg, jpegtran, rdjpgcom and wrjpgcom. Cjpeg compresses an image file into JPEG format. Djpeg decompresses a JPEG file into a regular image file. Jpegtran can perform various useful transformations on JPEG files. Rdjpgcom displays any text comments included in a JPEG file. Wrjpgcom inserts text comments into a JPEG file.

The libpng-devel package contains header files and documentation necessary for developing programs using the PNG (Portable Network Graphics) library. If you want to develop programs which will manipulate PNG image format files, you should install libpng-devel. You'll also need to install the libpng package.

Fontconfig is designed to locate fonts within the system and select them according to requirements specified by applications.

The OpenJDK runtime environment.

Direct Rendering Manager runtime library

X.Org X11 libXext runtime library

Pango is a library for laying out and rendering of text, with an emphasis on internationalization. Pango can be used anywhere that text layout is needed, though most of the work on Pango so far has been done in the context of the GTK+ widget toolkit. Pango forms the core of text and font handling for GTK+. Pango is designed to be modular; the core Pango layout engine can be used with different font backends. The integration of Pango with Cairo provides a complete solution with high quality text handling and graphics rendering.
