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.
nAlpha
[in] Specifies the transparency level. Range of values is from 0 to 255. Value 0 means that srcPage is fully transparent, value 255 means that srcPage is fully opaque. If the alpha parameter is 255, this function is equal to function IIXC_Page::Place.
nFlags
[in] Combination of flags which specifies how the data will be copied. For more details about this parameter, see enum IXC_ColorFlags.
pRect
[in] Pointer to the RECT structure which defines the destination rectangle.

Return Value

Returns S_OK if operation was successful or error code in other cases.
