## 12. The "Change Document Conversion Parameters" dialog box

This dialog box is displayed by menu item Options → Customize Configuration → Change Document Conversion Parameters. This dialog box allows to specify the XSL style sheet parameters (e.g. `paper.type`=`USLetter`) used when converting the document being edited to other formats (e.g. PDF, HTML, etc).

Procedure 9.3. Adding a user-defined parameter

1. Select the conversion for which you want to specify parameters by using the "Group of parameters" combo box.

   In the above screen shot, the user has selected the conversion of DocBook documents to PDF or PostScript.

2. Click on the Add button.

   ### Tip

   If, for example, you want to redefine `paper.type` from `A4` to `USLetter` as shown in the above screen shot. Select the `paper.type` parameter by clicking on it and then click on the Add button. This will spare you the effort of retyping `paper.type` as the name of the parameter you want to add.

3. Specify the name of the parameter and its value in the dialog box displayed by the Add button and then click OK.

   The value of a parameter may contain whitespace, including newline characters.

4. Click OK if you are done or use "Group of parameters" combo box and the Add, Edit and Remove buttons to specify more parameters.

In the above screen shot:

- The user has added parameter `body.font.master`=`11`. (The default value of this parameter, as specified in the XSL style sheet, is 10.)

  Notice the star which precedes newly added and newly modified parameters.

- The user has redefined parameter `paper.type` to `USLetter`.

  Notice how the user-defined parameter follows the predefined, grayed, parameter.

### Tip

The Documentation link is supposed to open in your favorite Web browser the reference manual of the XSL style sheet parameters.

Therefore, If you select a parameter by clicking on it and then click on the Documentation link, you should be able to read the documentation of this parameter.

However, this is not guaranteed to work because:

1. This generally requires an access to the Internet.

2. This documentation is not always available. For example, there is no documentation about the XHTML XSL style sheets yet. In such case, you need to send a support request to the `<xmleditor-support@xmlmind.com>` public mailing list to learn how the document conversion process can be parametrized.

Procedure 9.4. Modifying a user-defined parameter

1. Select the conversion for which you want to specify parameters by using the "Group of parameters" combo box.

2. Select the parameter to be modified by clicking on it.

3. Click on the Edit button.

   Predefined, grayed, parameters cannot be modified.

4. Specify the value of the parameter in the dialog box displayed by the Edit button and then click OK.

   ### Tip

   It also possible to change the name of the parameter here. Doing this will simply add a new parameter or replace an existing one.

   In fact, the Add and Edit buttons may almost be used interchangeably.

5. Click OK if you are done or use "Group of parameters" combo box and the Add, Edit and Remove buttons to specify more parameters.

Procedure 9.5. Removing a user-defined parameter

1. Select the conversion for which you want to specify parameters by using the "Group of parameters" combo box.

2. Select the parameter to be removed by clicking on it.

3. Click on the Remove button.

   Predefined, grayed, parameters cannot be removed.

4. Click OK if you are done or use "Group of parameters" combo box and the Add, Edit and Remove buttons to specify more parameters.
