MapInfo TAB (MAPINFO/MITAB) Reader Parameters

This parameter is only applicable when opening datasets of Type FME. If the auxillary FME dataset is a database reader, then MapInfo willl not automatically put the password for the source database in the tab file. This parameter allows the user to specify the password dynamically. Additionally, if the password is hardcoded into the tab file, then this parameter will supercede that password.

This parameter is optional. However, if it is needed to open the FME dataset, then it will need to be provided on both generation and runtime.

This parameter is applicable only if you are working with foreign (non-English) character sets.

For example, if your source data contains foreign characters, using this parameter along with the encoding value ensures that the original data is preserved from the reader to the writer.

If the value is not set, the character encoding will be automatically detected from the source file. If the value is set, it will take precedence over the automatically detected character encoding.

FME supports most encodings.

Use this parameter to expose Format Attributes in Workbench when you create a workspace:

• In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
• In a non-dynamic scenario where you have multiple feature types, it is convenient to expose additional attributes using this one parameter. For example, if you have ten feature types and want to expose the same attribute in each one, it is easier to define it once than it is to set each feature type individually in the workspace.

Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned.

If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.

When selected, this parameter removes any portions of imported features being read that are outside the Search Envelope.

The example below illustrates the results of the Search Envelope when Clip to Search Envelope is not selected (set to No) and when it is selected (set to Yes).

• No: Any features that cross the search envelope boundary will be read, including the portion that lies outside of the boundary.
• Yes: Any features that cross the search envelope boundary will be clipped at the boundary, and only the portion that lies inside the boundary will be read. The underlying function for the Clip to Search Envelope function is an intersection; however, when Clip to Search Envelope is selected, a clipping operation is also performed in addition to the intersection.
