The command should be as follows:
convert -size 300x150 xc: -draw 'rectangle 0,0 40,140' -draw 'rectangle 260,0 300,140' -fill white -draw 'rectangle 15,8 285,132' -fill orange -pointsize 80 -draw "text 20,95 'PACKT'" -fill black -pointsize 27 -draw "text 68,147 'PUBLISHING'" Packt_logo.gif

ImageMagick is a free software suite to create, edit, and compose bitmap images using text-based commands. The commands can be issued from the command line, but more often will be included in web or desktop applications – carrying out complex image-manipulation tasks in response to the user's input.
ImageMagick is a popular way for generating images on-the-fly in web pages, whether it's generating thumbnails from a large image, or creating complex combinations of images, text, and effects chosen by a visitor or the web site's creator.
This fast paced and practical tutorial is packed with examples of photo manipulations, logo creation, animations, and complete web projects. With this book up your sleeve, you'll be creating spellbinding images from code in no time
