示例1: SharedSurf
bool
GLScreenBuffer::ReadPixels(GLint x, GLint y,
GLsizei width, GLsizei height,
GLenum format, GLenum type,
GLvoid* pixels)
{
// If the currently bound framebuffer is backed by a SharedSurface
// then it might want to override how we read pixel data from it.
// This is normally only the default framebuffer, but we can also
// have SharedSurfaces bound to other framebuffers when doing
// readback for BasicLayers.
SharedSurface* surf;
if (GetReadFB() == 0) {
surf = SharedSurf();
} else {
surf = mGL->mFBOMapping[GetReadFB()];
}
if (surf) {
return surf->ReadPixels(x, y, width, height, format, type, pixels);
}
return false;
