    libjpeg-turbo

    libjpeg-turbo

    SIMD-accelerated libjpeg-compatible JPEG codec library

    libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

    Octave Forge

    Octave Forge

    A collection of packages providing extra functionality for GNU Octave

    Octave Forge is a central location for collaborative development of packages for GNU Octave. The Octave Forge packages expand Octave's core functionality by providing field specific features via Octave's package system. See https://octave.sourceforge.io/packages.php for a list of all available packages. GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable. Refer to https://www.octave.org for more information.

    POSIX Threads for Windows

    An implementation of the POSIX threads API for Windows

    Also known as "pthreads-win32", POSIX Threads for Windows implements a large subset of the threads related API from the Single Unix Specification Version 3. Conformance and quality are high priorities of this mature library. Development began in 1998 and has continued with numerous significant professional contributions. Please note:- whilst PThreads4W can be built and run by it, MinGW64 includes it's own default POSIX Threads library called "winpthreads". The two are not compatible and in order to build and run PThreads4W (formerly PThreads-WIn32) MinGW64 must be installed without win32pthreads. If you want or need to build and run with PThreads4W then you need to choose win32 threading instead of POSIX when you install MinGW64 to not install the conflicting winpthreads include and library files.

    PHPMailer

    PHPMailer

    The classic email sending library for PHP

    PHPMailer – A full-featured email creation and transfer class for PHP. Support for UTF-8 content and 8bit, base64, binary, and quoted-printable encodings. SMTP authentication with LOGIN, PLAIN, CRAM-MD5, and XOAUTH2 mechanisms over SMTPS and SMTP+STARTTLS transports. Validates email addresses automatically. Many PHP developers need to send email from their code. The only PHP function that supports this directly is mail(). However, it does not provide any assistance for making use of popular features such as encryption, authentication, HTML messages, and attachments. Formatting email correctly is surprisingly difficult. There are myriad overlapping (and conflicting) standards, requiring tight adherence to horribly complicated formatting and encoding rules – the vast majority of code that you'll find online that uses the mail() function directly is just plain wrong, if not unsafe!

PhpSpreadsheet is a library written in pure PHP and offers a set of classes that allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc. Support for PHP versions will only be maintained for a period of six months beyond the end of life of that PHP version. Use composer to install PhpSpreadsheet into your project. Or also download the documentation and samples if you plan to use them. A good way to get started is to run some of the samples. Don't forget to download them via --prefer-source composer flag. And then serve them via PHP built-in webserver. PhpSpreadsheet relies on Composer autoloader. So before working with PhpSpreadsheet in standalone, be sure to run composer install.

    Spleeter

    Spleeter

    Deezer source separation library including pretrained models

    Spleeter is the Deezer source separation library with pretrained models written in Python and using Tensorflow. It makes it easy to train music source separation models (assuming you have a dataset of isolated sources), and provides already trained state of the art models for performing various flavours of separation. 2 stems and 4 stems models have state of the art performances on the musdb dataset. Spleeter is also very fast as it can perform separation of audio files to 4 stems 100x faster than real-time when run on a GPU. We designed Spleeter so you can use it straight from command line as well as directly in your own development pipeline as a Python library. It can be installed with Conda, with pip or be used with Docker.

    pikepdf

    pikepdf

    A Python library for reading and writing PDF, powered by QPDF

    pikepdf is a Python library allowing the creation, manipulation, and repair of PDFs. It provides a Pythonic wrapper around the C++ PDF content transformation library, QPDF. Python + QPDF = “py” + “qpdf” = “pyqpdf”, which looks like a dyslexia test and is no fun to type. But say “pyqpdf” out loud, and it sounds like “pikepdf”. pikepdf is a library intended for developers who want to create, manipulate, parse, repair, and abuse the PDF format. It supports reading and write PDFs, including creating from scratch. Thanks to QPDF, it supports linearizing PDFs and access to encrypted PDFs.

    mPDF

    mPDF

    PHP library generating PDF files from UTF-8 encoded HTML

    mPDF is a PHP library that generates PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files ‘on-the-fly’ from his website, handling different languages. It is slower than the original scripts e.g. HTML2FPDF and produces larger files when using Unicode fonts, but support for CSS styles etc. and has been much enhanced. Supports almost all languages including RTL (Arabic and Hebrew), and CJK (Chinese-Japanese-Korean). Nested block-level elements (e.g. P, DIV) including margins, borders, padding, line height, background colors, etc. Right-to-left languages are supported, with automatic detection of RTL characters within a document. Transposes tables, lists, text justification, and table cell alignment, as well as a full-text reversal for RTL characters. Automatically detects non-RTL characters and displays these in the original order.

    OpenH264

    OpenH264

    Open Source H.264 Codec

    Cisco has taken their H.264 implementation and open-sourced it under BSD license terms. Development and maintenance will be overseen by a board from the industry and the open-source community. Furthermore, we have provided a binary form suitable for inclusion in applications across a number of different operating systems and made this binary module available for download from the Internet. We will not pass on our MPEG-LA licensing costs for this module, and based on the current licensing environment, this will effectively make H.264 free for use on supported platforms. OpenH264 is a codec library which supports H.264 encoding and decoding. It is suitable for use in real-time applications such as WebRTC. Constrained Baseline Profile up to Level 5.2 (Max frame size is 36864 macro-blocks). Arbitrary resolution, not constrained to multiples of 16x16. Rate control with adaptive quantization, or constant quantization.

    Dompdf

    Dompdf

    HTML to PDF converter for PHP

    dompdf is an HTML to PDF converter. At its heart, dompdf is (mostly) a CSS 2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer, it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes. PDF rendering is currently provided either by PDFLib or by a bundled version the R&OS CPDF class written by Wayne Munro. (Some important changes have been made to the R&OS class, however). In order to use PDFLib with dompdf, the PDFLib PECL extension is required. Using PDFLib improves performance and reduces the memory requirements of dompdf somewhat, while the R&OS CPDF class, though slightly slower, eliminates any dependencies on external PDF libraries.
