when I display the image though, the background is shown as white.
i'm using the following code to load the image based on the demo.
should I be setting some openGL parameter beforehand?
thanks
-a
filename = ("frog01.png")
texture = Texture(filename)
stimulus = TextureStimulus3D(texture=texture,
shrink_texture_ok=1,
internal_format =
gl.GL_RGBA,
mipmaps_enabled=0,
texture_min_filter=gl.GL_LINEAR,
texture_mag_filter=gl.GL_LINEAR)
