Welcome PrivateEye is an image viewer for RISC OS. It requires RISC OS 3.6 or later and a Boot sequence with the Nested Wimp and a 32-bit Shared C Library. Features • Loads and displays bitmap and vector images • Sprites, JPEGs, GIFs and PNGs • DrawFiles and ArtWorks • Bitmap effects • Adjust gamma, brightness and contrast • Blur and sharpen • Change saturation and apply histogram effects • Alpha channel support • Bitmap rotation with interactive preview • Rotation is lossless for JPEGs • Native JPEG display using SpriteExtend • Inbuilt lossless “cleaning” transparently loads progressive JPEGs • JFIF, Exif and Adobe metadata information display • Multiple-channel histogram PrivateEye • Display images may be saved • Convert JPEGs, GIFs and PNGs to into Sprites Image Viewer • Any number of images may be open concurrently by David Thomas, © 1999–2017 • Customisable key map version 3.00 (08 Feb 2017) • Lots of interactive help (use it!) Supported Image Formats PrivateEye converts images as necessary into a JPEGs RISC OS-native format. This means that GIFs, PNGs and (optionally) JPEGs are converted into Sprite format when RISC OS’s SpriteExtend module, version 0.99 or later, is used they are loaded. to directly display JPEGs. This allows images larger than available free memory to be displayed by decompressing The converted image is referred to as the display image. and plotting on the fly. Operations such as saving, rotation and the effects system operate on the display image only. Progressive (multiple scan) JPEGs are supported. PrivateEye has an inbuilt version of jpegtran which automatically Sprites converts JPEGs into a baseline format that SpriteExtend can render. -
Wakefield 2006 RISC OS Computer Show
I would like to welcome you all to this, our eleventh annual show in Wakefield. There have been many ups and downs over the last eleven years, since the first show at Cedar Court, organised in thirteen weeks, which ended up taking over the entire hotel. Ever since then, we have been at our current venue of Thornes Park. Over the years we have had many interesting attractions and features, such as the guest appearance by Johnny Ball one year. Of course, the show has seen many new hardware and software launches and previews over the years, some more successful then others: Kinetic, Peanut, Phoebe, StrongARM, Vantage, RiScript and so on. In fact, this year it is ten full years since we saw the very first StrongARM at the first Wakefield Show, as well as being the 25th Anniversary of the BBC Micro! Even now, we still have people developing for this famous microcomputer, which helped to start the home computer revolution. Be sure to visit both the JGH BBC Software and Domesday System stands during your visit. The Domesday Project is another superb example of how advanced we were with the BBC Master and other Acorn products of the 1980s. Now we are looking to the future with the new A9home, which is expected to be on retail sale or available for ordering at the show. Over the years we have had visitors to the show from all over the world, from countries such as New Zealand, Australia, South Africa, Belgium, Finland, Sweden and the USA; not bad for an amateur show! Another long-standing attraction of the show is of course the charity stall, which allows redundant equipment to be recycled, and through your kind support the stall has raised many thousands of pounds, primarily for the Wakefield Hospice, over the years. -

Oral History of Hermann Hauser; 2014-06-20
Oral History of Hermann Hauser Interviewed by: Gardner Hendrie Recorded: June 20, 2014 Cambridge, United Kingdom CHM Reference number: X7214.2014 © 2014 Computer History Museum Oral History of Hermann Hauser Gardner Hendrie: Today we have with us Hermann Hauser, who has very graciously agreed to do an oral history for the Computer History Museum. Thank you very much, Hermann. I think I'd like to start with a little bit of your early family background, sort of have an understanding of where you came from, and it might give us some insight as to how you ended doing what you did. Hermann Hauser: OK sure. Well I was born in Vienna. My mother is Viennese, but my father is Tyrolean, so I actually grew up in the Tirol, although my father sent my mother back to Vienna to have me in the Rudolfinerhaus hospital in Vienna, but I grew up in the Tirol, which is the mountainous part of Austria where the skiing is, and we had a ski lift behind our house. I went to school in the local village. It was a tiny village that I grew up in with about 200 people or so. And with a very small local school, primary school. And then I went to Kufstein, which is about 15 kilometers from where I lived which actually was a very small part of Wörgl was called Bruckhäusl, which really was a little village that got attached to Wörgl. Hendrie: Excuse me, now did you have any brothers or sisters? Hauser: Yes. I have one brother who is five years younger than me. -
