gozer - a commandline text renderer
gozer [options] [file]
gozer is a commandline text rendering utility for creating images from
abitrary text in antialised truetype fonts using optional fontstyles,
wordwrapping and layout control. gozer uses the imlib2 library to
create and save images. gozer has a few options, detailed below.
Specify [file] as the filename to save the rendered text to. Options
can also be specified in an rc file , allowing you to save commonly
used options (such as fontpaths) for reuse. The rc file $HOME/.gozerrc
is always parsed for default settings, and other rc files can be
specified on the commandline to override these options. See RC FILES
for information on syntax.
display help output and exit.
output version information and exit.
-b, --background COL
use COL as the background color, see COLOUR_DEFINITIONS for
syntax, default is transparent (0,0,0,0).
-f, --foreground COL
use COL as the foreground color. Default is white
-F, --font STR
draw using font STR. Size is specified with the name, eg
’arial/12’ for 12pt arial, default is 20thcent/16 (a font supplied
-j, --justification STR
justify text, allowed values for STR are left, right, center or
block. Default is left.
-l, --line-spacing INT
separate multiple lines by INT pixels, default 1.
-p, --fontpath STR
colon seperated list of font directories to search for fonts in.
Best used in the RCFILE to save typing it each time.
-q, --quality INT
1-100, effects quality of output for certain formats, e.g. jpeg
compression (higher means higher quality).
Pipe input text from standard in instead of reading it from a
-r, --rc-file STR
use STR as the rc file to look for extra options, default is
-s, --style STR
use STR as a file to load a fontstyle from, see FONTSTYLES for
-t, --text STR
use STR as text to draw.
-T, --textfile STR
read text to draw from file STR.
-w, --wrap INT
wordwrap the text to INT pixels.
-x, --x-offset INT
Offset text horizontally from top left by INT pixels.
-y, --y-offset INT
Offset text vertically from top left by INT pixels.
rc file syntax is simple. The ’#’ character at the start of a line
denotes that the line is a comment, otherwise lines are started with
the name of a long option from the commandline (without prefixing the
--), some whitespace and the value of the option. E.g.
NOTE that options in a --rc-file specified rc file OVERRIDE those from
the commandline, but the $HOME/.gozerrc file is always read first for
You can define colours in 4 ways. Using the html style: #RRGGBB (in
which case alpha defaults to 255),
#RRGGBBAA, or an alternative style:
r,g,b or r,g,b,a (no spaces between commas please).
eg for white text, either use #ffffff, #ffffffff, "255,255,255" or
"255,255,255,255". For red, #ff0000, #ff0000ff or "255,0,0" etc.
fontstyles can be defined in the EFM syntax (for compatibility only,
these are not as powerful), or the recommended syntax defined here.
The first line contains the line:
The second, an optional style name,
There follows a list of layers. Each is described by this rule:
RED GREEN BLUE ALPHA X_OFFSET Y_OFFSET
The special values or 0,0,0,0 for red, green, blue and alpha specify
the positioning of the actual text in it’s selected colour.
For example, the following style defines a very simple shadow for text:
0 0 0 128 -3 -3
0 0 0 0 0 0
