Hi there, Th file i thi librar ar intende t provid yo wit mean o gettin a th Doubl Hig Resolutio (DHR graphic o you Appl // o //GS althoug the haven' bee teste o //G yet Th librar file hav bee compresse usin Crunch23 The contents are as follows: DHIRES.DZR ;the graphics driver FAST2E.DZR ;the text driver SOFTIIE.DZR ;the SoftVideo replacement driver DHR.IZC ;Turb Pasca includ fil fo DHR graphics PGRAF.PZS ;A very simple demo program in Turbo Pascal PGRAF.CZM ;The above program compiled FRAC.PZS ;Turbo Pascal fractal generator source code FRAC.CZM ;compiled Turbo Pascal fractal generator DHR.CZ ;A header/include file for BDS C CGRAF.CZ ;Th simpl dem progra above but in BDS C CGRAF.CZM ;The C version compiled DHIRES.DZC ;This documentation. Ther ar severa importan thing yo shoul kno abou thi se o programs: First, the new SoftVide ha t b smaller t mak roo fo th graphic scree i th //e As a result it does not contain th Alte Mod (afte lookin a i once I'v no use i since an th functio ke syste (ther ar severa CP/M-base replacements) Th type-ahea syste remain intact Althoug haven' trie it th CONFIGSV.CO progra shoul stil work. SOFTIIE.DVR must still be driver #1. Second DHIRES.DV absolutel mus b drive #2 followin SOFTIIE.DVR I yo plac i anywher else you compute will crash the first time you try to plot with it. Last tex scree handlin i don usin FAST2E.DVR I i replacement for FAST2E80.DVR. It i slightl faste tha th original. Thos o yo wh us 650 interrupts wil b please t hea that unlik it parent FAST2E.DV wil no mes the around. The driver will handle enhaced //e character sets properly. I thi incarnation th DHIRES.DV i prett simple- minde program I operate i tw modes black-and-whit an colour whic hav t b selected Th scree ca b cleare t black whit o an o th 1 DH colours I black-and-whit mode yo ca plo o unplo pixel I yo plo o whit screen nothin wil see t change Ditto i yo unplo o blac screen I othe words plo set pixe an unplo reset it I colour yo ca onl plo i on o th 1 colours I blac an white functio wil le yo kno i pixe i se o not I return non-zer i th pixe i white zer i i i black I colou mode th functio return th colour of the pixel at the x,y co-ordinates. Th fil DHR.IN i Turb Pasca includ fil tha provide a eas interfac t th graphic driver Mos o th procedure an function ar writte i Pascal bu th tw tha uploa (t th Z80 an downloa (t th Apple a entir doubl hire scree hav som inlin assemble i them Thi wa necessary for speed. Turbo's fast, but not that fast. Fo thos o yo wh don' kno Pascal th DHR.IN fil shoul b rea prett muc lik paragrap o text You'l ge th gis o things The comments added recently might help. I yo d us anothe languag interfac DON' FORGE T CLI TH PIXELS Colou x, shoul b limite t 0-139,0-191 B& t 0- 559,0-191. Ther i header/includ fil fo BD i ther somewhere too It' prett direc translatio fro th Pasca version s yo won' hav muc troubl wit it don' think It' interestin tha th Turb versio o th simpl dem progra i quit bi faste tha th BD thing hadn' expecte that Th DHR. fil shoul b spli i two heade fil wit al th #defin entries an anothe o th function compile t library. Up to you. Th driver - SoftIIe Fast2 an Dhire - coul stan som improvement can' se goo reaso fo ther bein thre drivers fo on thin (the woul b one, i wasn' s lazy) Also ther i bi o roo lef (abou $A bytes betwee th en o th drive cod an th star o th graphic scree fo somethin o other Som o yo migh hav like t hav use th spac take u b th extensiv look-u table fo mor sophisticate graphic routines lik ar an lin drawers didn' d i mysel becaus fel tha th balanc o time/workloa betwee th Z80/650 wa abou righ a i was Tha is ther wouldn' b muc spee gai b doin mor i th 6502 Speed think i mos importan t graphic an th existin schem (thoug no necessaril th existin code shoul provid abou a muc spee a ca b had Look-u table ar big, but they're fast. Enough of this.
