* imlib2 based hook
* Copyright (c) 2002 Philip Gladstone
*
- * This module implements a text overlay for a video image. Currently it
- * supports a fixed overlay or reading the text from a file. The string
- * is passed through strftime so that it is easy to imprint the date and
- * time onto the image.
- *
- * You may also overlay an image (even semi-transparent) like TV stations do.
- * You may move either the text or the image around your video to create
- * scrolling credits, for example.
- *
- * Text fonts are being looked for in FONTPATH
- *
- * Options:
- *
- * -C <rgb.txt> The filename to read RGB color names from
- * Defaults if none specified:
- * /usr/share/X11/rgb.txt
- * /usr/lib/X11/rgb.txt
- * -c <color> The color of the text
- * -F <fontname> The font face and size
- * -t <text> The text
- * -f <filename> The filename to read text from
- * -x <expression> X coordinate of text or image
- * -y <expression> Y coordinate of text or image
- * -i <filename> The filename to read a image from
- * -R <expression> Value for R color
- * -G <expression> Value for G color
- * -B <expression> Value for B color
- * -A <expression> Value for Alpha channel
- *
- * Expressions are functions of:
- * N // frame number (starting at zero)
- * H // frame height
- * W // frame width
- * h // image height
- * w // image width
- * X // previous x
- * Y // previous y
- *

* This module is very much intended as an example of what could be done.

* One caution is that this is an expensive process -- in particular the
