Given the complexity of the rendering, you might be surprised it is accomplished by a single command-line: magick -size 320x90 canvas:none -stroke snow4 -size 1x90 -tile gradient:white-snow4 \ Here we show percent completion of a task as a shaded cylinder: However, very few may realize the second, more complex command, gives a flat two-dimensional label a three-dimensional look with rich textures and simulated depth: Without knowing much about the ImageMagick command-line, you can probably surmise that the first command above converts an image in the JPEG format to one in the PNG format. 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.įor most command line examples on this site, if there is an equivalent translation to run on windows there will be a dropdown in the bottom right, letting you switch which operating system you are previewing the command for. 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 \( -clone 0 -shade 110x50 -normalize -channel BG -fx 0 +channel -alpha Off \) \ \( +clone -shade 110x90 -normalize -negate +clone -compose Plus -composite \) \ Or it can be complex with a plethora of options, as in the following: magick label.gif -alpha Set \ The ImageMagick command-line tools can be as simple as this: magick image.jpg image.png
