<meta name="description" content="ImageMagick® is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, JPEG-2000, GIF, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves."/>

<p>AnnotateImage() annotates an image with text. Optionally you can include any of the following bits of information about the image by embedding the appropriate special characters:</p>
<pre class="text">
\n newline
\r carriage return
< less-than character.
> greater-than character.
& ampersand character.
a percent sign
b file size of image read in
c comment meta-data property
d directory component of path
e filename extension or suffix
f filename (including suffix)
g layer canvas page geometry (equivalent to "WxHXY")
h current image height in pixels
i image filename (note: becomes output filename for "info:")
k CALCULATED: number of unique colors
l label meta-data property
m image file format (file magic)
n number of images in current image sequence
o output filename (used for delegates)
p index of image in current image list
q quantum depth (compile-time constant)
r image class and colorspace
s scene number (from input unless re-assigned)
t filename without directory or extension (suffix)
u unique temporary filename (used for delegates)
w current width in pixels
x x resolution (density)
y y resolution (density)
z image depth (as read in unless modified, image save depth)
A image transparency channel enabled (true/false)
C image compression type
D image GIF dispose method
G original image size (wxh; before any resizes)
H page (canvas) height
M Magick filename (original file exactly as given, including read mods)
O page (canvas) offset ( = XY )
P page (canvas) size ( = WxH )
Q image compression quality ( 0 = default )
S ?? scenes ??
T image time delay (in centi-seconds)
U image resolution units
W page (canvas) width
X page (canvas) x offset (including sign)
Y page (canvas) y offset (including sign)
Z unique filename (used for delegates)
@ CALCULATED: trim bounding box (without actually trimming)
# CALCULATED: 'signature' hash of image values
