L_LTIVW_API L_INT L_DispContainerBurnTag(pBitmap, uRow, uAlign, pString, pFontFamily, nFontStyle, fFontSize, bShadow, nShadowColor, nColor, uFlags)

Burns the tag onto the bitmap.

Parameters

pBITMAPHANDLE pBitmap

Pointer to the bitmap handle of the bitmap on which the tag is burned.

L_UINT uRow

A zero-based index representing the line at which the overlay text will be drawn.

L_UINT uAlign

Value that specifies the origin point from which to count the rows specified in the uRow parameter. For example, if uAlign is DISPWIN_ALIGN_BOTTOMLEFT and uRow is 4, the tag is placed counting 4 rows from the bottom. Possible values are:

Value Meaning
DISPWIN_ALIGN_TOPLEFT [0x0000] Start counting rows from the top of the cell. The tag is left-justified.
DISPWIN_ALIGN_LEFTCENTER [0x0001] The tag is placed in the center, based on the height of the cell, and is left-justified.
DISPWIN_ALIGN_BOTTOMLEFT [0x0002] Start counting rows from the bottom of the cell. The tag is left-justified.
DISPWIN_ALIGN_TOPCENTER [0x0003] The tag is placed in the center, based on the width of the cell, and is top-justified.
DISPWIN_ALIGN_BOTTOMCENTER [0x0004] The tag is placed in the center, based on the width of the cell, and is bottom-justified.
DISPWIN_ALIGN_TOPRIGHT [0x0005] Start counting rows from the top of the cell. The tag is right-justified.
DISPWIN_ALIGN_RIGHTCENTER [0x0006] The tag is placed in the center, based on the height of the cell, and is right-justified.
DISPWIN_ALIGN_BOTTOMRIGHT [0x0007] Start counting rows from the bottom of the cell. The tag is right-justified.

LPTSTR pString

A character string specifying the tag's text.

L_TCHAR *pFontFamily

Pointer to variable specifying the font family to which the font belongs.

L_INT nFontStyle

A variable specifying the font style of the text.

L_FLOAT fFontSize

A boolean flag that indicates whether to include text shadowing in the burn process. Possible values are:

Value Meaning
TRUE Include text shadowing in the burn process.
FALSE Exclude the text shadow in the burn process.
