+ @section m17n-dump-description DESCRIPTION
Dump a text as PNG image file.
So, the default behaviour is the same as specifying "cat >
%s.png" as FILTER.
+ If FILTER is just "-", the PNG image is written to stdout.
+
<li> -a
Enable anti-alias drawing.
Prefer a font specified for the language LANG. LANG must be a
2-letter code of ISO 630 (e.g. "en" for English).
+ <li> -fg FOREGROUND
+
+ Specify the text color. The supported color names are those of
+ HTML 4.0 and "#RRGGBB" notation.
+
+ <li> -bg BACKGROUND
+
+ Specify the background color. The supported color names are the
+ same as FOREGROUND, except that if "transparent" is specified,
+ make the background transparent.
+
+ <li> -r
+
+ Specify that the orientation of the text is right-to-left.
+
<li> -q
Quiet mode. Don't print any messages.
</ul>
