Projection problem Mercator Oblique

hi,
i have a problem with "Hotine Oblique Mercator B" seems that is insensitive at AZIMUTH ANGLE parameter.

For replicating the problem try this, using coordinate converter:

Input Coordinate:
X=392937.9206
Y=5818466.7383

Input coordinate system:
EPSG 25833

Output coordinate system:
HOTINE OBLIQUE MERCATOR B
DATUM: WGS84
PLANAR UNITS: METERS
CENTER SCALE FACTOR: 1
AZIMUT ANGLE: XXXXXXXX
AMIUTH PT 13.421146
ORIGIN LATITUDE 52.504883
FALSE EAST 1000
FALSE NORTH 2000

Global Mapper tested on v16, v17, v18, v19
XXXXXXXX = 5 then X=1097.815 and Y=2102.188
XXXXXXXX = 30 then X=1097.815 and Y=2102.188
XXXXXXXX = 45 then X=1097.815 and Y=2102.188
XXXXXXXX = 60 then X=1097.815 and Y=2102.188
XXXXXXXX = -45 then X=1097.815 and Y=2102.188


with proj.4
XXXXXXXX = 5 then X=1087.6814 and Y=2109.5443
XXXXXXXX = 30 then X=1033.1709 and Y=2136.3366
XXXXXXXX = 45 then X=996.7541 and Y=2140.2763
XXXXXXXX = 60 then X=960.5585 and Y=2134.6564
XXXXXXXX = -45 then X=1140.2763 and Y=2003.2459

Many Thanks for attention
Mario

    Hello Mario,

    I suggest that you report this directly to Blue Marble Geographics Support via email (geohelp@bluemarblegeo.com). The will be able to figure out what is going on.
