The AlphaPlace method copies a specified rectangular area from one page into another using a specified level of transparency. If the alpha parameter is 255, this function is equal to function IIXC_Page::Place.

Syntax

HRESULT AlphaPlace([in]  IIXC_Page*  srcFrom,
                   [in]  LONG        nSX,
                   [in]  LONG        nSY,
                   [in]  UCHAR       nAlpha,
                   [in]  ULONG       nFlags,
                   [in]  RECT*       pRect);

Parameters

srcFrom

[in] Pointer to IIXC_Page of the source page from which the area is to be copied.

nSX

[in] Specifies the x-coordinate, in pixels, of the upper-left corner of the source rectangle.

nSY

[in] Specifies the y-coordinate, in pixels, of the upper-left corner of the source rectangle.
