# TPVAPIDrawPageInfo

This structure defines the parameters used by the VAPIMWP_DRAW_DRAWPAGE message to draw a page into a device context.

## Syntax

    #include <kvvapi.h>
    typedef struct tag_TPVAPIDrawPageInfo
    {
        HDC                hdc;
        unsigned int       nPage;
        RECT               Rect;
        RECT               RectUsed;
        BOOL               bCentre;
        HBRUSH             hBrush;
    }
    TPVAPIDrawPageInfo;

## Members

`hdc` | The device context in which to draw the page.
`nPage` | The number of the page to draw. Page numbers start at 0. For example, set `uPage` to `0` to draw page 1, and to `1` to draw page 2. For word processing documents, pages must be drawn sequentially. For example, to draw page 3, you must first draw pages 0 and 1. If the `bWait` member of `TPVAPIOpenDocumentInfo` is set to `FALSE`, you can draw any page. See TPVAPIOpenDocumentInfo. If the page you request is beyond the last page, a `VAPI_RETURN_NO_PAGE` error is returned.
`Rect` | A rectangle in the device coordinates specifying where to draw the page.
`RectUsed` | Returns the rectangle that the page was actually drawn in. `RectUsed` might be different than `Rect` because Viewing maintains the aspect ratio of the document.
`bCentre` | Because `RectUsed` might be different than `Rect`, this flag specifies whether the page should be centered in `Rect`.
`hBrush` | The handle of a brush used to paint the background when `RectUsed` is different than `Rect`. If this is `NULL`, the background is not filled.
