<DIV><FONT size=2>Hello,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I have a question about the GDALWarp usage:</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>after the transfer of raster image (gray scale
orthophoto) from one coordinate system to another (Gauss Boaga - UMT ED50)
around the orthophoto it appears a black frame that remain and create
visualization problems when I proceed with the mosaic of many
orthophoto.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>How can I resolve this problem ? There is in GDALWarp a way
(options) to render this black frame transparent during the process of
coordinate system transformation ? And what is the write sintax ?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Waiting for your answer ...</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Thank you !</FONT></DIV>
