Several of the export filters allow users to specify how blanked nodes in the export source data are represented in the export file. Each of these filters has controls in the Export Options dialog that are associated with blanking, including the following.
Blank Type Combobox
The combo box determines what value is used to replace any blanked nodes in the exported lattice. The possible selections are:
· Data Minimum— Any blanked nodes are replaced with the smallest data value in the export source lattice.
· Data Maximum— Any blanked nodes are replaced with the largest data value in the export source lattice.
· Type Minimum— Any blanked nodes are replaced with the smallest value permissible for the export data type. For example, if the data exported is unsigned integers, the minimum value is zero; however, if the data exported is signed 16-bit integers, the minimum value is -32768.
· Type Maximum— Any blanked nodes are replaced with the largest value permissible for the export data type. For example, if the data exported is unsigned 8-bit integers, the maximum value is 255; however, if the data exported is signed 16-bit integers, the maximum value is 32767.
· Fixed— Any blanked nodes are replaced with the value entered in the Blank Value control (see below).
Blank Value Edit Box
If Fixed is selected in the Blank Type control (see above), the value in this editbox replaces any blanked nodes in the exported lattice.
