MCF Version Out
The version of Mercator MCF to output. Version 6.4 allows only integer values, whereas Version 7.0 allows decimal values. If 7.0 is specified, the default values for OFFSET_X, OFFSET_Y, SCALE_X, SCALE_Y are 0, 0, 1, 1 respectively.
Note: Version 7.0 may be called by another term.
Horizontal Size
The horizontal size of the dataset, in Mercator units, to output into the job file. One Mercator unit is 1/256000 of an inch. If a feature of type mcf_job enters the writer and this keyword is not set, the job file will have the largest horizontal size from all of the job features. If this keyword is not specified and there are no input job features, the job file output will have the value 2956651 (A4 width in Mercator units).
Vertical Size
The vertical size of the dataset, in Mercator units, to output into the job file. One Mercator unit is 1/256000 of an inch. If a feature of type mcf_job enters the writer and this keyword is not set, the job file will have the largest vertical size from all of the job features. If this keyword is not specified and there are no input job features, the job file output will have the value 2118144
Offset (X)
The floating point value by which all x-coordinates are offset. For MCF-to-MCF translations, this value is set to 0. If this value is not set, the writer calculates its own offset to bring the coordinates to the origin of (0,0).
All MCF data is two-dimensional.
Offset (Y)
The floating point value by which all y-coordinates are offset. For MCF-to-MCF translations, this value is set to 0. If this value is not set, the writer calculates its own offset to bring the coordinates to the origin of (0,0).
Scale (X)
The floating point value by which all x-coordinates are scaled. A value of 1 leaves the x-coordinates of the incoming features as is. For MCF-to-MCF translations, this value defaults to 1 but can be changed in the mapping file. If this value is not specified, and MCF Version Out is 6.4, the writer calculates its own scale factor that is as large as possible to minimize the loss of precision when decimal coordinates are stored as integers in MCF.
Scale (Y)
The floating point value by which all y-coordinates are scaled. For MCF to MCF translations, this value defaults to 1 but can be changed in the mapping file. The writer flips the y-coordinates over the x-axis because of MCF’s origin. If this value is not specified, and MCF Version Out is 6.4, the writer calculates its own scale factor that is as large as possible to minimize the loss of precision when decimal coordinates are stored as integers in MCF.
