Extra note:
MapInfo uses a large integer to describe it's internaly used colors.
Here is a C# function to convert MapInfo color code to RGB: as you can
see, the MapInfo color code is in format BGR instead of RGB.
Maybe this has to do with your problem?
private static Color miColorCodeToRGB(Int32 miColorCode)
{
Int32 iRed;
Int32 iGreen;
Int32 iBlue;
Int32 _miColorCode;
try
{
_miColorCode = miColorCode;
//lColor = lColor \ &H100 'divide
//iGreen = lColor Mod &H100 'get green component
iRed = _miColorCode % 0x100;
_miColorCode = _miColorCode / 0x100;
iGreen = _miColorCode % 0x100;
_miColorCode = _miColorCode / 0x100;
iBlue = _miColorCode % 0x100;
Color _Color = Color.FromArgb(255,iBlue, iGreen, iRed);
return _Color;
}
catch
{
return Color.Transparent;
}

Hi List
I am trying to make use of the colour binding feature, and it
basically works, except... the colours are not quite right. My
colours do not match those in MapInfo, although I can make MapInfo
emulate the MapServer colours by swapping blue and green around. So
basically: my RGB values are interpreted by MapServer as RBG.
This happens for polygons as well as lines (haven't tried points). My
data has been translated from MapInfo to PostGIS.
I tried to lodge a bug in Trac, but it says "TICKET_CREATE privileges
are required to perform this operation"
Does anyone know more about this colour problem?
Jacob,
With some pointers from Howard, I found this segment of code in
bindColorAttribute() in maputil.c:
attribute->red = atoi(tokens[0]);
attribute->blue = atoi(tokens[1]);
attribute->green = atoi(tokens[2]);
I think this is responsible. If you are building from source, try just
changing it to the more obvious organization. I'd also suggest you
file a bug in Trac on the issue we will see if there is a subtle reason
for this, or it's just a typo.
To file bugs you need an OSGeo Userid. The pointer to get an osgeo
userid which you can use to login with is under the title "Important
Notice" on the http://trac.osgeo.org/mapserver page. The same userid
can be used for other OSGeo services like subversion, and other
trac instances (like GDAL's).
Best regards,
