[magick-users] Making a Drop Shadow Text Image

[Fred Weinhaus]

You can use the color "none" with xc: as  (xc:none) to make a 
transparent background image.
You can use any color defined per http://imagemagick.org/script/color.php

Make the background much bigger than you need, add the text, then use 
-trim to trim the excess area, then use -border to add any border 
back that you want.

I have a script also that does lots of text effects. See texteffect script at

>Hello,

>I just read the thread on 'Adding text to an image' and it has inspired me

>text and its color will be parameters to the script. The background of the
>final image is to be transparent.

>To that end I need to learn the following:
>1. What parameters may I use to 'xc:'?
>2. Once I have a text on a suitable background how can I determine the
>bounding box for the text and cut the image to that size?
>3. If I can do step 2 then I can create the same text in say a dark gray for
>the shadow. How do I apply a small guassian blur to the shadow image?
