106 INKSCAPE – FREE VECTOR GRAPHICS EDITOR Grabareva A
INKSCAPE – FREE VECTOR GRAPHICS EDITOR Grabareva A. Supervisor: Voevodina M. E-mail: [email protected], [email protected] Kharkiv, О.М. Beketov National University of Urban Economy in Kharkiv Inkscape is a cross-platform, powerful enough and in many ways competitive free vector graphics editor with open source code, and in which the SVG format is used as the main standard for work. It is convenient for creating both artistic and technical illustrations. Inkscape is an analogue of such graphic editors as Corel Draw, Adobe Illustrator, Xara X and Freehand. Intended use: - illustrations for office circulars, presentations, creation of logos, business cards, posters; - technical illustrations (diagrams, graphics, etc.); - vector graphics for high-quality printing (with preliminary import of SVG into Scribus); - web graphics – from banners to site layouts, icons for applications and website buttons, - graphics for games. Main characteristics of Inkscape: - the program is free and distributed under the GNU General Public License; - cross-platform; - the program supports the following document formats: import – almost all popular and frequently used formats: SVG, JPEG, GIF, BMP, EPS, PDF, PNG, ICO, and many additional ones, such as SVGZ, EMF, PostScript, AI, Dia, Sketch, TIFF, XPM, WMF, WPG, GGR, ANI, CUR, PCX, PNM, RAS, TGA, WBMP, XBM, XPM; export – the main formats are PNG and SVG and many additional EPS, PostScript, PDF, Dia, AI, Sketch, POV-Ray, LaTeX, OpenDocument Draw, GPL, EMF, POV, DXF; - there is support for layers; - -

OM-Cube Project
OM-Cube project V. Hiribarren, N. Marchand, N. Talfer [email protected] - [email protected] - [email protected] Abstract. The OM-Cube project is composed of several components like a minimal operating system, a multi- media player, a LCD display and an infra-red controller. They should be chosen to fit the hardware of an em- bedded system. Several other similar projects can provide information on the software that can be chosen. This paper aims to examine the different available tools to build the OM-Multimedia machine. The main purpose is to explore different ways to build an embedded system that fits the hardware and fulfills the project. 1 A Minimal Operating System The operating system is the core of the embedded system, and therefore should be chosen with care. Because of its popu- larity, a Linux based system seems the best choice, but other open systems exist and should be considered. After having elected a system, all unnecessary components may be removed to get a minimal operating system. 1.1 A Linux Operating System Using a Linux kernel has several advantages. As it’s a popular kernel, many drivers and documentation are available. Linux is an open source kernel; therefore it enables anyone to modify its sources and to recompile it. Using Linux in an embedded system requires adapting the kernel to the hardware and to the system needs. A simple method for building a Linux embed- ded system is to create a partition on a development host and to mount it on a temporary mount point. This partition is filled as one goes along and then, the final distribution is put on the target host [Fich02] [LFS]. -

Of Computer and Information Science at Linköpings universitet Abstract The KreaTV Application Development Kit (ADK) product of Motorola en- ables application developers to create high level applications and browser plugins for the IPSTB system. As a result, customers will reduce develop- ment time, cost and supplier dependency. The main goal of this thesis was to port this platform to a standard Linux PC to make it easy to trace the bugs and debug the code. This work has been done by implementing a hardware abstraction layer(HAL)for Linux Operating System. HAL encapsulates the hardware dependent code and HAL APIs provide an abstraction of underlying architecture to the oper- ating system and to application software. So, the embedded platform can be emulated on a standard Linux PC by implementing a HAL for it. We have successfully built the basic building blocks of HAL with some performance degradation. -
Implementing a Parametric EQ Plug-In in C++ Using the Multi-Platform VST Specification
2003:044 C EXTENDED ESSAY Implementing a parametric EQ plug-in in C++ using the multi-platform VST specification JONAS EKEROOT SCHOOL OF MUSIC Audio Technology Supervisor: Jan Berg 2003:044 • ISSN: 1402 – 1773 • ISRN: LTU - CUPP - - 03/44 - - SE Implementing a parametric EQ plug-in in C++ using the multi-platform VST specification Jonas Ekeroot Division of Sound Recording School of Music in Pite˚a Lule˚aUniversity of Technology April 23, 2003 Abstract As the processing power of desktop computer systems increase by every year, more and more real-time audio signal processing is per- formed on such systems. What used to be done in external effects units, e.g. adding reverb, can now be accomplished within the com- puter system using signal processing code modules – plug-ins. This thesis describes the development of a peak/notch parametric EQ VST plug-in. First a prototype was made in the graphical audio program- ming environment Max/MSP on MacOS, and then a C++ implemen- tation was made using the VST Software Development Kit. The C++ source code was compiled on both Windows and MacOS, resulting in versions of the plug-in that can be used in any VST host application on Windows and MacOS respectively. Writing a plug-in relieves the programmer of the burden to deal directly with audio interface details and graphical user interface specifics, since this is taken care of by the host application. It can thus be an interesting way to start developing audio DSP algorithms, since the host application also provides the op- portunity to listen to and measure the performance of the implemented plug-in algorithm. -
