Several questions:<br>* is there a better routine to call to just change pixel format?<br>* is there a way to turn off data scaling within sws_scale so that it only changes format?<br>* which file / what module or subroutine contains the code that actually measures and rescales the gray values of an image so that i can see exactly how this is being done ?<br><br>thanks<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:12.0pt'><o:p> </o:p></span></b></p><p class=MsoNormal><b><span style='font-size:12.0pt'>Jim Morgenstern<o:p></o:p></span></b></p><p class=MsoNormal>Image Mining LLC<o:p></o:p></p><p class=MsoNormal>248-252-2626<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
