StarInfo/Tanner/!GenBackDr/!Help
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

!GenBackDr ========== (c) T. R. Tanner email tomt@selwood.demon.co.uk Drop a file into the icon & it will set the backdrop. The backdrop icon will be regenerated if the wimp mode changes. The "Scaling" option allows controlling of scaling & tiling of the picture on the backdrop. The "Processing" menu option allows selection / control of various changefsi flags. The "Save" option allows the current state (i.e. icon, etc) to be saved permamently. NB The actual "default" backdrop will be regenerated when the machine is rebooted (or !GenBackDr is restarted) if required. The "Reset" option resets the backdrop to the options at the last save. NOTES ===== 1/ If you wish to turn on the grid lock (*Pinboard -Grid), you will wipe out the backdrop (IMHO, this is a bug). => If you do this in a boot sequence, do it before !GenBackDrop is started! 2/ The program uses CHANGEFSI to generate the sprite for the backdrop. If CHANGEFSI can't handle it, this can't. 3/ The program was written using CHANGEFSI 0.98 or so & the parameters to this DO NOT conform to the documentation. However, I Can't check the version number sensibly. 4/ Pinboard is too pessimistic about how much space it needs to load a backdrop sprite, so don't blame me if there is buckets of free ram and you get an error saying "Not Enough Memory To Load Backdrop Sprite". Pinboard is lying. 5/ Interactive help & desktop save are supported. TO COME ======= Have a quick grovel about in the code, you'll see what I haven't done yet (or properly).
