hi all,
I want to capture the screen ,what I have done is to add a eventhandler in
which I add code like this
osg::ref_ptr<osg::Image> image = new osg::Image;
image->readPixels(0,0,m_iWidth,m_iHeight, GL_RGB,GL_UNSIGNED_BYTE);
osgDB::writeImageFile(*image,"D:\\abc.bmp");
what I get is blank image.
I googled that maybe I should do this in DrawCallBack. I eagerly want to know
why my code doesn't work. Is pixel in FBO erased before EventTraverse ?
Thanks for any hint
best regards
