Hi,
I'm trying to test speed of the OpenGL accelerated Java2D drawing ops (to
compare to JAI and direct memory manipulation), but when I try to allocate a
VolatileImage to draw on, I get a message that the OpenGL pipeline failed to
initialize. I'm trying to allocate a 2000x3000 pix ARGB image, but it doesn't
look like it's failing because of memory. I have an Ubuntu linux laptop with a
Radeon GL video card:
ATI Technologies Inc Radeon RV200 LX [Mobility FireGL 7800 M7]
I'm running JDK 1.6.0_02
Here's the output from using "export J2D_TRACE_LEVEL=4":
[I] GLXGC_FindBestVisual: scn=0

[I] OGLFuncs_OpenLibrary

[E] GLXGC_InitFBConfig: could not find an appropriate fbconfig
[E] GLXGraphicsConfig_getGLXConfigInfo: could not create fbconfig
Could not enable OpenGL pipeline for default config on screen 0
And this is the code where I'm trying to set it up:
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsConfiguration gc =
ge.getDefaultScreenDevice().getDefaultConfiguration();
VolatileImage image = gc.createCompatibleVolatileImage(width, height,
Transparency.TRANSLUCENT);
Graphics2D g = image.createGraphics();
I'm really new to creating VolatileImages (previously this was BufferedImage
but it was very slow), so if I'm setting something up wrong please let me know.
Thanks,
Derek
