All,
I'm developing a 2D demo that scrolls a wide image in a resolution of 640 x
480 of 16 bits. To do this I use a rendering loop that uses a
BufferStrategy (JDK 1.4).
My problem is that I would like to have a page flipping strategy to have the
best results, but it seems that the program isn't able to use that strategy.
It uses a blitting strategy instead witch causes tearing effects in the
demo. To discover that the program doen't do page flipping, I request the
BufferCapabilities class. The call to isPageFlipping() always returns false
and the call to getFlipContents() always returns null because
isPageFlipping() returns false, according to the API doc.
I don't understand why page flipping can't be used because my video card has
2 megs of VRAM so this should be big enough to perform page flipping (2
pages of 640 x 480 x 16). Also I run the demo in Windows 98.
Any help would be greatly appreciated.
Thanks
Jerome
