X_offset real An offset in X axis.To calculate the distance the name should be offset in millimetres at 1:50000 use the following formula: Distance in mm = (X_offset *size) *0.3528; eg (0.5*3.5)*0.3528 = 0.62mm
'0.5'
Y_offset real An offset in Y axis.To calculate the distance the name should be offset in millimetres at 1:50000 use the following formula: Distance in mm = (Y_offset *size) *0.3528; eg (0.5*3.5)*0.3528 = 0.62mm
'0.5'
size real Used in conjunction with the X and Y offsets in a formula to determine text position.
