FADER II¢by Patrick L. Dell'Era¢¢(From ANTIC, MAY 1985, p. 57)¢¢This is an enhancement of the¢popular "Fader" program that¢appeared in the September, 1984¢ANTIC. The original program created¢a dot-by-dot "lapse-dissolve" effect¢on Micro Painter files. Fader II¢now works on Micro Illustrator¢pictures as well. It will work on¢all Atari computers with 48K and¢disk drive.¢Last month, we published Patrick¢Dell'Era's reworking of Philip¢XXX¢Price's "Picture Painter." We now¢present Patrick's Fader II, based¢upon the popular dot-by-dot picture¢dissolve program by Joseph Grande¢that ANTIC printed in the September¢1984 graphics issue.¢The original Fader was written in¢the BASM language, which is now¢often hard to find. Patrick has¢disassembled the object code into¢full MAC/65 source code, and¢re-written it with several¢improvements.¢SLIDE SHOW II¢Unlike the original program, Fader¢II can handle both uncompressed and¢XXX¢compressed Graphics 7+ picture¢files. This means you can have any¢combination of Micropainter or Micro¢Illustrator files on the same disk.¢(Micro Illustrator software comes¢with the KoalaPad, the Atari Touch¢Tablet and other widely used¢graphics products.)¢So that Fader II can tell the¢difference between the file types,¢you must use a .PIC extender on your¢compressed files. The Micro Painter¢files should have a letter other¢than P).¢Fader II will cycle through the each¢picture creating a screen pixel¢XXX¢dissolve. When it reaches the last¢file, it will begin again with the¢first. As with the original program,¢you may skip the pause between¢pictures by pressing [START].¢In Fader II, after a picture fades¢in, it may be held indefinitely on¢the screen by pressing [OPTION]. In¢this way, one may take a good look¢at a particularly fetching piece of¢art, or gracefully change the disk¢without racing the clock. If you¢have DOS on your disk, pressing¢[SELECT] will take you to it.¢Fader II does not sit in the DUP.SYS¢area of memory, so a Binary Load can¢XXX¢be done on it from DOS without¢creating a MEM.SAV file. It will¢run with or without a cartridge¢installed.¢Patrick L. Dell'Era is a member of¢the San Francisco Atari users' group¢ABACUS, and a strong assembly¢language programmer whose time is¢currently being taken up with a new¢baby.¢əəəəəəəəəəəəəəəəəə
