Keywords: Interlace ViewPorts ScrollVPort Message-ID: Date: 3 Apr 91 23:30:54 GMT Sender: news@sco.COM Distribution: comp Lines: 25 HELP! I was trying to write a program which used Views and ViewPorts to allow fast scrolling of an interlaced image. I got the initial setup done which allowed me to show an image, but when I called ScrollVPort(), it seemed to flip the odd and even lines. I was able to get this to work with a non-interlaced display. Does anyone have any ideas? It looks like ScrollVPort is not resetting one of the copper lists (2 for interlaced ViewPorts) correctly, or is doing something to corrupt it. Suggestions? I need to finish this program soon, so a quick answer/solution would be appreciated! thanks brian moffet -- O Fortuna - velut luna - statu variabilis - semper crescis - aut decrescis vita detestabilis - nunc obdurat - et tunc curat - ludo mentis aciem egestatem - potestatem - dissolvit ut glaciem brianm@sco.com Speaking for Myself
