Pyglet is a library for the Python programming language that provides an object-oriented application programming interface for the creation of games and other multimedia applications. [ 1 ] [ 2 ] pyglet runs on Microsoft Windows , macOS , and Linux ; it is released under the BSD Licence . pyglet was first created by Alex Holkner.
Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7. [3]
Matrix pencils play an important role in numerical linear algebra.The problem of finding the eigenvalues of a pencil is called the generalized eigenvalue problem.The most popular algorithm for this task is the QZ algorithm, which is an implicit version of the QR algorithm to solve the eigenvalue problem = without inverting the matrix (which is impossible when is singular, or numerically ...
Pencil2D is a free and open-source 2D animation software for Windows, macOS, and Unix-like operating systems. It is released under the GNU General Public License and uses the Qt framework . It is used for making cartoons using traditional techniques (tracing drawings, onion skinning , etc), managing vector and bitmap drawings.
The language centers on a model of a pencil programmatically drawing on a 2-dimensional screen, with the pencil cursor visually depicted as a turtle. A 2019 study by Deng et al. in an eight-week teaching intervention comparing text-based and block-based environments found that students learning in a mixed environment had improved confidence and ...
Processing is a free graphics library and integrated development environment (IDE) built for the electronic arts, new media art, and visual design communities with the purpose of teaching non-programmers the fundamentals of computer programming in a visual context.
Cairo supports output (including rasterisation) to a number of different back-ends, known as "surfaces" in its code.Back-ends support includes output to the X Window System, via both Xlib and XCB, Win32 GDI, OS X Quartz Compositor, the BeOS API, OS/2, OpenGL contexts (directly [7] and via glitz), local image buffers, PNG files, PDF, PostScript, DirectFB and SVG files.
Generalized pencil-of-function method (GPOF), also known as matrix pencil method, is a signal processing technique for estimating a signal or extracting information with complex exponentials. Being similar to Prony and original pencil-of-function methods, it is generally preferred to those for its robustness and computational efficiency.
