28 mdump [ OPTION ... ] [ FILE ]
30 @section mdump-description DESCRIPTION
32 Dump a text as PNG image file.
34 The PNG file is written to a file created in the current directory
35 with the name "BASE.png" where BASE is the basename of FILE. If
36 FILE is omitted, text is read from standard input, and the image
37 is dumped into the file "output.png".
39 The following OPTIONs are available.
45 SIZE is the font size in point. The default font size is 12 point.
49 DPI is the resolution in dots per inch. The default resolution is
54 PAPER is the paper size: a4, a4r, a5, a5r, b5, b5r, letter, WxH,
55 or W. In the case of WxH, W and H are the width and height in
56 millimeter. In the case of W, W is the width in millimeter. If
57 this option is specified, PAPER limits the image size. If FILE is
58 too large for a single page, multiple files with the names
59 "BASE.01.png", "BASE.02.png", etc. are created.
63 MARGIN is the horizontal and vertical margin in millimeter. The
64 default margin is 20 mm. It is ignored when PAPER is not
69 POS is the character position of cursor to draw. By default,
74 FILE is assumed to be an XML file generated by the serialize
75 facility of the m17n library, and FILE is deserialized before an
80 Each line is broken at word boundary.
84 FILTER is a string containing a shell command line. If this
85 option is specified, the PNG image is not written info a
86 file but is given to FILTER as standard input. If FILTER
87 contains "%s", that part is replaced by a basename of FILE.
88 So, the default behaviour is the same as specifying "cat >
93 Enable anti-alias drawing.
97 Prefer a font whose family name is FAMILY.
101 Prefer a font specified for the language LANG. LANG must be a
102 2-letter code of ISO 630 (e.g. "en" for English).
106 Quiet mode. Don't print any messages.
110 Print the version number.
