<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have started using gl2ps functionality recently. It satisfies my need to capture 3d scene at different times of rendering.<o:p></o:p></p>
<p class="MsoNormal">I use it in my code as below<o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none"><i><span style="font-size:9.5pt;font-family:Consolas;color:#0070C0"> state = GL2PS_OVERFLOW;<o:p></o:p></span></i></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also gl2ps is used for printing text in PS file in same scene like below.<o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:9.5pt;font-family:Consolas;color:#0070C0"> glRasterPos3d(sx, yr, sz);<o:p></o:p></span></p>

<p class="MsoNormal" style="text-autospace:none"><span style="font-size:9.5pt;font-family:Consolas;color:#0070C0"><o:p> </o:p></span></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:9.5pt;font-family:Consolas"><o:p> </o:p></span></p>
<p class="MsoNormal">Now when I get the generated PS file it is not covering complete scene.<o:p></o:p></p>
<p class="MsoNormal">I have attached the screenshot and the generated PS file with this mail.<o:p></o:p></p>
<p class="MsoNormal">Please write back to me if there is any solution so that complete scene can be captured in this PS file.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">PS: Currently I am using ‘Rampant Logic Postscript Viewer’ version 1.2 for opening this PS file which opens it in adobe reader.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Let me know if the problem is in the viewer and not while generating the PS file.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks in advance.<o:p></o:p></p>
<p class="MsoNormal">Regards,<o:p></o:p></p>
