The mail was down here last night so I don't think this got out. Let me try again. Randy -----Forwarded message----- Date: Mon, 6 Oct 1997 23:02:41 -0400 From: Randall Hopper <rhh@ct.picker.com> Subject: [video] bktr clipping Started trying out the bktr clipping half hour ago and noticed a few small bugs. My tests have been very minimal, but so far what I've noticed is that the driver seems to swap X and Y (X and Y defined per display convention and as X does), and the Y coordinates (X, with the swap bug) are doubled when capturing both fields. The latter's probably just a loop stepping typo. For example, with this clip rect: (X 10, Y 50) - ( X 20, Y 100 ) with single field, what gets clipped is: (X 50, Y 10) - ( X 100, Y 20 ) and with double field, it's: (X 50, Y 20) - ( X 100, Y 40 ) Will continue working with it tomorrow ev. BTW, this is with the 971005 driver off of rah. Thanks, Randall -----End of forwarded message-----
