mdraw_coordinates_position

mdraw_coordinates_position(3m17n)				 The m17n Library				 mdraw_coordinates_position(3m17n)

NAME

       mdraw_coordinates_position - Return the character position nearest to the coordinates.

SYNOPSIS

       int mdraw_coordinates_position (MFrame * frame, MText * mt, int from, int to, int x_offset, int y_offset, MDrawControl * control)

DESCRIPTION

       Return the character position nearest to the coordinates. The mdraw_coordinates_position() function checks which character is to be drawn
       at coordinate (x, y) when the text between from and to of M-text mt is drawn at the coordinate (0, 0) using the mdraw_text_with_control()
       function with the drawing control object control.  Here, the character position means the number of characters that precede the character
       in question in mt, that is, the character position of the first character is 0.

       frame is used only to get the default face information.

RETURN VALUE

	   If the glyph image of a character covers coordinate (x, y), mdraw_coordinates_position() returns the character position of that
	   character.

	    If y is less than the minimum Y-coordinate of the drawn area, it returns from.

	    If y is greater than the maximum Y-coordinate of the drawn area, it returns to.

	    If y fits in with the drawn area but x is less than the minimum X-coordinate, it returns the character position of the first character
	   drawn on the line y.

	    If y fits in with the drawn area but x is greater than the maximum X-coordinate, it returns the character position of the last
	   character drawn on the line y.
