Hi,
Below are sections from 2 different gdalinfo listings:
RGB that displays the way we expected in MapServer
Band 1 Block=256x256 Type=Byte, ColorInterp=Red
Band 2 Block=256x256 Type=Byte, ColorInterp=Green
Band 3 Block=256x256 Type=Byte, ColorInterp=Blue
----------------------
RGB that displays as a gray scale in MapServer
Band 1 Block=1394x1 Type=Byte, ColorInterp=Red
Band 2 Block=1394x1 Type=Byte, ColorInterp=Green
Band 3 Block=1394x1 Type=Byte, ColorInterp=Blue
What does 1394x1 mean (one level deep)?
John,
1394x1 is the internal blocksize in the file. It basically means that
the file in question is being accessed scanline by scanline, while the
other is read in chunks of 256x256 tiles.
The second image that shows up as gray scale within MapServer shows up
as color within the global mapper desktop application. Is their
anything that could be done to change the header info within the file (
i.e. running gdalwarp against the grayscale appearing image so that
MapServer recognizes it as RGB)?
There is no reason obvious from the gdalinfo output that mapserver would
have trouble showing the second image in RGB.
Best regards,
