oListener=CREATEOBJECT("ReportListener")

REPORT FORM MyReport PREVIEW OBJECT oListener
cOutputFile = "c:\testreport(1).bmp"
oListener.OutputPage(1, cOutputFile, 105, 0, 0, 768, 1024)

It works but the header and footer images are not align like with report form preview or html output file (using htmllistener). The header and footer height & width are streched too short. How to avoid that?
