"- Sicuramente un post per gli studenti di "Editing multimediale" della IUL ma anche per tutti quelli a cui capita di lavorare con le immagini - Grafica bitmap e vettoriale - Due o tre cose sui formati più noti, GIF, PNG e JPEG, sulla compressione delle informazioni, conservativa e non, e sui formati "dedicati" XCF e SVG - Gimp e Inkscape, due bellissimi software liberi per l'elaborazione delle immagini che girano su Linux, Mac e Windows - Elaborazione delle immagini in livelli" ---- [Titoli:] Primo fatto: software libero anziché proprietario Secondo fatto: distinguere fra grafica bitmap e vettoriale > Immagini digitali > dpi e risoluzione > Tipi di grafica > Grafica bitmap > Grafica vettoriale > Formati - compressione > Manipolando foto > Fabbricando immagini > Lavorare in grafica bitmap con Gimp > Lavorare in grafica vettoriale con Inkscape Terzo fatto: usare i livelli (layers) Coda Note

0 July 2013 Last updated at 08:52 GMT Help 3D printing has been around for some time but now the technology is available for the same price as a top-end TV at shops. 3D printing has been hailed as the future of manufacturing. The technology works by building up layer upon layer of material - typically plastic - to build complex solid objects. The idea is that as the printers become cheaper, instead of buying goods from shops, consumers will instead be able to download designs and print out the items at home. Technology Correspondent Rory Cellan-Jones has been finding out what 3D print stores offer

"WHAT IS CIRCOS? CIRCULAR VISUALIZATION Circos is a software package for visualizing data and information. It visualizes data in a circular layout - this makes Circos ideal for exploring relationships between objects or positions. There are other reasons why a circular layout is advantageous, not the least being the fact that it is attractive. Circos is ideal for creating publication-quality infographics and illustrations with a high data-to-ink ratio, richly layered data and pleasant symmetries. You have fine control each element in the figure to tailor its focus points and detail to your audience."

"This course is focused on the potential of blended learning to transform the way we setup classrooms and schools.  We are not focused on simply putting computers into classrooms or layering technology on top of the existing system.  This course focuses on the highest-quality blended learning we have seen so far, and schools that are working to get closer to the golden ideal of every student getting exactly what they need, when they need it.  We'll cover the basics of blended learning and then move quickly into all the implications for the role of the student, the role of the teacher, and the implications for how we design and run our schools. "

"ELAN is a professional tool for the creation of complex annotations on video and audio resources. With ELAN a user can add an unlimited number of annotations to audio and/or video streams. An annotation can be a sentence, word or gloss, a comment, translation or a description of any feature observed in the media. Annotations can be created on multiple layers, called tiers. Tiers can be hierarchically interconnected. An annotation can either be time-aligned to the media or it can refer to other existing annotations. The textual content of annotations is always in Unicode and the transcription is stored in an XML format. ELAN provides several different views on the annotations, each view is connected and synchronized to the media playhead. Up to 4 video files can be associated with an annotation document. Each video can be integrated in the main document window or displayed in its own resizable window. ELAN delegates media playback to an existing media framework, like Windows Media Player, QuickTime or JMF (Java Media Framework). As a result a wide variety of audio and video formats is supported and high performance media playback can be achieved. ELAN is written in the Java programming language and the sources are available for non-commercial use. It runs on Windows, Mac OS X and Linux. Main other features navigate through the media with different step sizes easy navigation through existing annotations waveform visualization of .wav files support for template documents input methods for a variety of script systems multi-tier regular expression search, within a single document or in a selection of annotation documents support for user definable Controlled Vocabularies import and export of Shoebox/Toolbox, CHAT, Transcriber (import only), Praat and csv/tab-delimited text files export to interlinear text, html, smil and subtitles text printing of the annotations multiple undo/redo Download ELAN"

Il software serve ad annotare video e audio: sembra piuttosto complesso ma è prodotto e offerto dal progetto The Language Archive dell'Istituto Max Plank dei Paesi Bassi, perciò sembra abbastanza sicuro. Ho installato la versione per Mac: poi provo e riporto
