Most of the modifications I made were tagged or noted in some way in the
text_gui libraries in FF. The very first changes weren't,
unfortunately, and buggered if I can remember what they were. Something
to do with the mouse pointer when changing the focus, I think.
It would take a patient person some time to find and transfer the bug
fixes to the "official" text_gui, and as they only affect the graphics
incarnation of the library it wouldn't for instance improve the ee
editor at all.
It's possible a determined person could reverse the FF text_gui
libraries back into the general-purpose equivalents. This could prove
as difficult.. colour.e and xle.e have been signifigantly changed for
embedded links in help text and stuff. Parts of scroll.e and the GUI
graphic Motif lookalike library motif.e has also been altered for 8x8
font sizes. All the other graphic lookalike libraries would possibly
require simalar modification to maintain consistency.
The question is.. would anyone benefit from all the effort? Who (other
than me?!) persists with the old text_gui when win/dos32lib is just
about as easy to code with, promises portability and gives better
results in graphics modes anyway.
I can't say I've seen any progs use text_gui other than my two (dump and
FF) and ee with it's variants. Are there any I'm not aware of?
-- Off the topic:
I have recently completed a routine to apply convolution filters to 256
colour images in virtual screens. I plan to add this feature to the
next release of FF, but if anyone is interested I could make it into a
general purpose library for all. It is coded mainly in assembler and
runs reasonably fast.
The filters I have for it so far include edge detect, blur, enhance,
sharpen, emboss and plenty of psychadelic effects. It would probably
require some kind of virtual screen library for any resolution other
than mode #13.
It doesn't work on all images, they need a continuously shaded palette.
Greyscale images would work just fine. Images of fractals often work
quite well. Portraits, landscapes and reduced-colour images usually end
up as fuzz.
Is this something somebody would find useful?
