ImageGear allows you to store the DIB resolution - biXPelsPerMeter and biYPelsPerMeter fields of AT_DIB structure - in different units depending on a global parameter; this function allows you to get the current value of this parameter. Valid values are IG_RESOLUTION_INCHES and IG_RESOLUTION_METERS. The default value is IG_RESOLUTION_METERS.
