IIXC_Page::AlphaTile Method

Revision as of 02:08, 4 June 2015

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

Syntax

HRESULT AlphaTile([in]  RECT*       stDestRect,
                  [in]  IIXC_Page*  pSrcPage,
                  [in]  RECT*       stSrcRect,
                  [in]  LONG        nOriginX,
                  [in]  LONG        nOriginY,
                  [in]  UCHAR       nAlpha,
                  [in]  ULONG       nFlags);

Parameters

stDestRect

[in] Pointer to RECT structure which defines the destination rectangle.

pSrcPage

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

stSrcRect

[in] Pointer to RECT structure which defines the rectangle into srcPage page which should be tiled onto destPage page.

nOriginX

[in] Specifies the x-coordinate, in pixels, of the upper-left corner of the source rectangle which will be used for tiling.

nOriginY

[in] Specifies the y-coordinate, in pixels, of the upper-left corner of the source rectangle which will be used for tiling.

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::Tile.

nFlags

[in] Combination of flags which specifies how the data will be copied. For more details about this parameter, see enum IXC_ColorFlags.

Return Value

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