The pdDocSetFilter function applies the visibility filter to any text output generated by D-Type Power Engine. This filter disables the display of the shadow, body, outline and/or underline layers when D-Type Power Engine renders text. By default, the visibility filter is off, meaning that all four layers (shadow, body, outline, underline) are visible when D-Type Power Engine renders text.
| Parameter | Description |

power_doc |
Handle of the associated Power Engine document. |

reserved |
Reserved for future use. Must be set to 0. |
|
filter |
Visibility filter. This value is a combination of three independent bit values which indicate which of the four layers (shadow, body, outline, underline) will be suppressed when D-Type Power Engine renders text.
|
If successful, the return value is 1. Otherwise, the function returns 0.
The following table illustrates the effect of the visibility filter on text output.
