NAME

       mdraw_text -

SYNOPSIS

       int mdraw_text (MFrame * frame, MDrawWindow win, int x, int y, MText * mt, int from, int to)

DESCRIPTION

       Draw an M-text on a window. The mdraw_text() function draws the text between from and to of M-text mt on
       window win of frame frame at coordinate (x, y).

       The appearance of the text (size, style, color, etc) is specified by the value of the text property whose
       key is Mface. If the M-text or a part of the M-text does not have such a text property, the default face
       of frame is used.

       The font used to draw a character in the M-text is selected from the value of the fontset property of a
       face by the following algorithm:

       1.  Search the text properties given to the character for the one whose key is Mcharset; its value should
           be either a symbol specifying a charset or Mnil. If the value is Mnil, proceed to the next step.
       Otherwise,  search  the mapping table of the fontset for the charset. If no entry is found proceed to the
       next step.

       If an entry is found, use one of the fonts in the entry that

        has a glyph for the character and that matches best with the face properties. If no  such  font  exists,
       proceed to the next step.
       2.  Get  the  character  property  'script' of the character. If it is inherited, get the script property
           from the previous characters. If there is no previous character, or  none  of  them  has  the  script
           property other than inherited, proceed to the next step.
       Search the text properties given to the character for the one whose key is Mlanguage; its value should be
       either a symbol specifying a language or Mnil.
       Search  the  mapping  table of the fontset for the combination of the script and language. If no entry is
       found, proceed to the next step.

       If an entry is found, use one of the fonts in the entry that

        has a glyph for the character and that matches best with the face properties. If no  such  font  exists,
       proceed to the next step.
       3.  Search  the  fall-back  table  of the fontset for a font that has a glyph of the character. If such a
           font is found, use that font.
       If no font is found by the algorithm above, this function draws an empty box for the character.
       This function draws only the glyph foreground. To specify the background color, use mdraw_image_text() or
       mdraw_text_with_control().
       This function is the counterpart of XDrawString(), XmbDrawString(), and XwcDrawString() functions in  the
       X Window System.

RETURN VALUE

           If  the  operation was successful, mdraw_text() returns 0. If an error is detected, it returns -1 and
           assigns an error code to the external variable merror_code.

ERRORS

           MERROR_RANGE
