Why bother with an Acorn?
One of my reasons for buying an Acorn machine was to learn about computers (again), not just use one. No doubt that makes me a bit of a rarity in today's world, but I must say that I've got real satisfaction from doing all the code, graphics and animations by hand.
So, apart from the computer itself, what did all these fancy graphics designers, animators and programming tools cost? These web-tools are all freeware....what a superb system RISC OS/Acorn is:

A web browser, made by Acorn. This is what started it all, because there's a 'view source code' button !Browse is also what I use initially to view the finished product (will it ever be 'finished'?). Gives structured help with pretty pictures, if the content has it in. It was made by Guttorm Vik. There is structured help available for a variety of subjects by various authors, but for me; stage II of learning HTML came courtesy of StrongHTML - a manual by Guttorm Vik. StrongHTML has all the HTML with it's appropriate syntax + more. Forget the rest - this is all you need. This is a text/program editor, also by Guttorm Vik. Right, once I've got itchy HTML fingers, I fire up this application. It has many 'modes' to choose from; funnily enough I choose HTML mode (these modes have useful tools for each purpose). Alternatively, you could use !Edit the text editor supplied with every Acorn, but !StrongED is free and offers more, so why not... Download it along with !StrongHelp and StrongHTML (approx.500K in total) A sprite (bitmap) editor which is supplied with every Acorn. Hmmm, I thought; these pages need some illustrations to enliven them, so I used this proggy. For starters anyway... A vector graphics application which is supplied with every Acorn. !Draw is ace for re-sizing or re-orienting (eg. rotating) graphics and text fonts. There is a (gratuitous) spinning Morris emblem on a page in the Cars Dept. as an example of this. Also the titles of the pages were created with !Draw. Converts many image formats into sprites or JPEGs. It is supplied with all RiscPCs (at least). JPEGs are very efficient on space, and any JPEG on my site is created using this wee gem. Absolutely indespensible, quick and very easy to use - just drag and drop. It also offers easy scaling and other processing options. An added bonus of this application is it's ability to cut down the colours used by sprites eg. 256 to 16, or to colour to grey scale. The latest version (1.16) is only available with RISC OS 4; the latest version for people without RISC OS 4 is 1.15RC, available from R-Comp (290K long) Jclean and it's two companions: Jcut and Jsize are jpeg utilities. Jclean allows you to turn a 'normal' jpeg into a progressive one and/or optimise it so that the file ends up as small as possible with no degredation. Allows faster download times and less waste... Get these three from http://www.dacha.freeuk.com/ 'cos they're fab... This allows you to take a !Draw file (or !Artworks file) and turn it into a !Paint (bitmap) file. !ArttoSprite is by Tony Houghton.
!ArttoSpr can be found on Tony Houghton's site approx. 22K By Peter Hartley; turns sprites, drawfiles, ARmovies or GIFs into GIFs or sprites; both animated and static. It is freeware, it is amazing; it is indispensible! According to the author, it is one of the most efficient GIF creators anywhere - see his site for details: !InterGIF can be found on Peter Hartley's site approx. 75K This program by Tom Tanner can create sprites from PNGs or vice-versa. Download it from: here (70K) GifWizard.com This is not a RISC OS application, however you can feed a URL into it (online) and it'll almost instantly tell you how efficient your graphics (and HTML) are. If you run your RISC OS apps really well you can end up with files that are even more optimised than GifWizard.com can do. Ha Ha! (it's rated some of my works at 100% optimised). Try feeding someone elses webpage URL into it - it can be quite enlightening: www.gifwizard.com When everything is ready, uploading the files, piccys and data couldn't be simpler - !FTPc by Colin Granville is a PD file transfer program using true 'drag 'n' drop' in RISC OS fashion. It is fast and efficient to use. Get !FTPc from Colin's site, and watch out for updates - he works on it very often! (96K) |

And some acknowledgements too! Some sharp-eyed Acorn folk may recognise one or two things from !Poster, most notably the Big capital letters. These are !Draw files, which, after sizing; can be dragged straight to !InterGIF. !Draw has many uses, one of them is the ability to rotate sprites/text/whatever accurately via the:
An example of this is the wholly unnecessary and silly Morris emblem, in the Cars Dept. - this uses 10 frames (360° divided by 10 = 36°) After rotating each frame, I saved each !Draw file, converted them to a multiple !Paint sprite file (use !ArttoSpr) and cropped all the frames to be the same size - a requirement of animation using !InterGIF. Finally, I used !InterGIF to turn the sprite file into an animated GIF. An example of animation using !Paint is the tea cup one (Cars Dept.) For this the petrol pump and teacup were drawn, and this sprite was copied lotsa times. Each different frame was achieved by adding columns between the pump and cup using
Another example of adjusting the size of sprites was used to elongate the Morris Oxford brochure scanned in - it was shorter than the Morris Cowley one...no problem - using !Paint add some rows to the bottom and colour them in white! Both these sprites were loaded into !ChangeFSI, resized and turned into highly compressed JPEGs (30%-40% I think...) An example of the image mastering facilites of !ChangeFSI is the background of this page, which used a sprite from Tony Houghton's web-site. However, the original sprite was too dark to be useful, so I dragged it onto !ChangeFSI, and re-processed it with
I then saved it (using !ChangeFSI) as a monochrome JPEG at 70% compression, and it's a whopping 4Kbytes! Many web browsers cannot handle PNG graphic files at all well, so I had to change my home-page's background into something else. !Png2Spr changed it into a sprite, then !InterGIF to turn it into a highly compressed GIF...the resulting GIF was actually smaller than the original PNG! |
