In the next sections we dissect the anatomy of the ImageMagick command-line. To ensure the script can run under Windows, change any backslash-parens (\() to just parens, the backslash (\) to ^, and double-up the percent (%) signs. flatten -brightness-contrast 20,20 -normalize dragonFire.png

There are some other differences between Windows and Linux (involving quotation marks, for instance), but we'll discuss some of those issues later, as they arise. The parentheses that are escaped above using the backslash are not escaped in Windows. Line continuation characters need not be entered. Sometimes, however, the lines are wrapped by your browser if the browser window is small enough, but the command-lines, shown in white, are still intended to be typed as one line. We use the Linux style on these web pages, as above. In the Windows shell, use a carat character ( ^) for line-continuation. The backslash is the Linux line-continuation character. This example command is long enough that the command must be written across several lines, so we formatted it for clarity by inserting backslashes ( \). delete 0 +swap -compose Multiply -composite button.gif") \( -clone 0 -shade 110x50 -normalize -channel BG -fx 0 +channel -matte \) \
