Converts an attribute's value from one numeric system (base) to another, putting the resulting value in a new attribute. The base is the number of unique digits, including zero, that a positional numeral system uses to represent numbers.
The most common base values are 2 (binary), 10 (decimal) and 16 (hexadecimal), and 8 (octal). The BaseConverter supports bases from 2 (binary) to 36 (hexatridecimal / sexatrigesimal).
The feature type that contains the source attribute to be converted.
Features with the converted source attribute stored in a new attribute.
Choose the source attribute that contains the base to be converted.
Enter the base of the value to be converted.
Enter the base to which the value is to be converted.
The output width parameter specifies the total width of the output attribute. The value after conversion will be padded on the left with zeroes to make up the necessary width. If the width is set to 0, no padding is done. If the value is wider than the width before padding, it is not touched.
The name of the attribute that will contain the results, and will appear in the list of Output port attributes.
What if you want to convert a Microstation color to a KML color?
- Expose the igds_color.red, igds_color.green and igds_color.blue attributes.
Add three BaseConverter transformers.
- Edit the parameters so that each transformer converts one of the color values from base 10 to base 16.
- Use a StringConcatenator to combine the three color strings.
- This transformer supports only unsigned whole numbers. It does not handle fractions or decimal points.
- This transformer supports very large numbers.
- Digits are chosen from the set below. Any lowercase digits are automatically converted to uppercase.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
