Syntax UINT GetTextAlign( __in HDC hdc ); Parameters hdc [in] A handle to the device context. Return Value If the function succeeds, the return value is the status of the text-alignment flags. For more information about the return value, see the Remarks section. The return value is a combination of the following values. ValueMeaning TA_BASELINEThe reference point is on the base line of the text. TA_BOTTOMThe reference point is on the bottom edge of the bounding rectangle. TA_TOPThe reference point is on the top edge of the bounding rectangle. TA_CENTERThe reference point is aligned horizontally with the center of the bounding rectangle. TA_LEFTThe reference point is on the left edge of the bounding rectangle. TA_RIGHTThe reference point is on the right edge of the bounding rectangle. TA_RTLREADINGMiddle East language edition of Windows: The text is laid out in right to left reading order, as opposed to the default left to right order. This only applies when the font selected into the device context is either Hebrew or Arabic. TA_NOUPDATECPThe current position is not updated after each text output call. TA_UPDATECPThe current position is updated after each text output call. When the current font has a vertical default base line (as with Kanji), the following values are used instead of TA_BASELINE and TA_CENTER. ValueMeaning VTA_BASELINEThe reference point is on the base line of the text. VTA_CENTERThe reference point is aligned vertically with the center of the bounding rectangle. If the function fails, the return value is GDI_ERROR. Remarks The bounding rectangle is a rectangle bounding all of the character cells in a string of text. Its dimensions can be obtained by calling the GetTextExtentPoint32 function. The text-alignment flags determine how the TextOut and ExtTextOut functions align a string of text in relation to the string's reference point provided to TextOut or ExtTextOut. The text-alignment flags are not necessarily single bit flags and may be equal to zero. The flags must be examined in groups of related flags, as shown in the following list. TA_LEFT, TA_RIGHT, and TA_CENTER TA_BOTTOM, TA_TOP, and TA_BASELINE TA_NOUPDATECP and TA_UPDATECP If the current font has a vertical default base line, the related flags are as shown in the following list. TA_LEFT, TA_RIGHT, and VTA_BASELINE TA_BOTTOM, TA_TOP, and VTA_CENTER TA_NOUPDATECP and TA_UPDATECP To verify that a particular flag is set in the return value of this function: Apply the bitwise OR operator to the flag and its related flags. Apply the bitwise AND operator to the result and the return value. Test for the equality of this result and the flag. Examples For an example, see Setting the Text Alignment .
