Many years ago I was heavily involved in the viewdata industry - working for Micronet 800 and then producing software for other Prestel ISPs, running my own viewdata BBS, etc. I therefore accumulated rather a lot of viewdata pages, and managed to recover these from an old backup a few years ago.
As part of a separate project, Vewdata.org.uk I wanted to display these images. As they were saved using a BBC Micro, I loaded them up in a BBC Micro Emulator, under Windows, took a screen capture, pasted that into Photo Editor, cropped it, saved it out as a GIF, and finally uploaded it to the web server. I then had to add the image to whichever gallery it belonged in. As you can guess, this is fairly labour intensive, and gave rather variable results.
Being a firm believer in "let the computer" do the work, I started this side project to condense all this into as little work as possible. What I wanted to acheive was to reduce the steps to: 1. Upload original saved screen file to the web server. 2. End.
I think this has now achieved this, and more so! There are currently two scripts in the suite - vl.php (viewdata lister) will scan a given directory and construct a web page bsaed on the files it finds. vv.php is used as an image source for each file, and this reads the files and constructs a PNG or animated GIF, as appropriate, and returns it to the client.
As a side-benefit of having the original save file available, it's also possible to provide a text-only version of the frames! I hope this will make things more search-engine friendly.
So .. provided here are the scripts! Development is currently ongoing, so please check back if you are intending to use them. I've not yet got to the point where I have everything needed done for my actual use, so look forward to several verions yet! If you do any changes, please feed them back to me.
