style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">I’m trying to create geotiff files
for the first time and I was successful in creating a black and white geotiff.
So I moved on to creating a color one. I have a grid of RGB values so I created
a data set with 3 bands of type GDT_Byte. I used RasterIO to write out a
row at a time. The result was garbage. </SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Is there a specific order to writing
out bands? I first tried writing a row of red band, then a row of the green
band, then the row of the blue band. This didn’t work so I dried writing all of
rows for one band before writing the next. Am I way off on this? How should I be
doing this?</SPAN></FONT></P>
