<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I'm having problems with DirectX viewports under
Wine. I'm rendering to an offscreen surface and then copying the contents of the
offscreen surface to a window. I first set the viewport to coincide with the
window, i.e.
<BR>
<BR>
vp.X =
0;<BR>
vp.Y = 0;</FONT></DIV>
<DIV><FONT face=Arial
size=2>
vp.Width =
windowRect.Width();<BR>
vp.Height = windowRect.Height();</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I render most of the the scene using the above
viewport. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I then need to draw an arrow in the bottom left
hand corner of the of the window inside a square of side iSize, so I
set:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial
size=2>
vp.X =
0;<BR>
vp.Y = windowRect.Height() -
iSize;<BR>
vp.Width =
iSize;<BR>
vp.Height = iSize;</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Since iSize is only about a fifth of the window
height, I would expect the arrow to be displayed at the bottom left of the
window. but it's actually being displayed at the top left. The main part of the
scene rendered with the first viewport settings is fine.</FONT></DIV><FONT
face=Arial size=2>
<DIV><BR>The code does as expected in Windows, so I was wondering if anyone
knows of any problems in this area. I'm also having problems with CD3DFont which
I think might be related to this.</DIV>
<DIV> </DIV>
<DIV><BR>Thanks for any advice,</DIV>
<DIV> </DIV>
