![]() ![]() 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 \ So we don't recommend this program for those users who don't have some experience with the command line of the system or don't have enough patience to learn how to use the commands of this program since this program has not been developed to offer an advanced graphical interface where we can apply all the functionalities of the software.The ImageMagick command-line tools can be as simple as this: magick image.jpg image.png The possibilities this software offers to manipulate images are endless, so learning to manage this software will take time and dedication. ![]() We must remember that in Windows, this command is called “ imdisplay.” To run this command, we must type in the terminal: “ display picture.png.” In addition, it also allows us to apply a series of effects and modifications on the image: rotations modification of the brightness, saturation grayscale, zoom, adding frame, reduction noise, and more. For example, if we run “ identify photo.png,” it will display the information about the file “ photo.png.” This information includes resolution, size ( bytes), format, depth of color, and more.ĭisplay : this command opens the image file indicated. Identify : this command shows information about the graphic file. In addition to the “ convert” command, which is the main program's command, and that allows us to make any manipulations on images, there are 2 other commands that we will be able to use: That is to say it is possible that when we install one program, it requires us to install ImageMagick on our PC.įor the programmers, there are libraries in different programming languages ( Python, Java, Ruby, PHP, C, etc.) that allow us to incorporate the functions of image manipulation of this software in the programming routines. As we can observe, there are many options, so we will need to use some tutorials or buy one of the books which explain the use of this program in detail.īecause it is a program that runs from the command line, we probably need to install it as a requirement of other software. Once installed, we need to access the terminal and type in “ convert.” All the options of the program will be displayed. We need to download the package appropriate to our operating system (Windows, Linux, or Mac) to install the program. Thanks to these commands, we can convert the format of the images (e.g., from GIF to PNG), crop, reduce/enlarge, rotate, combine multiple images, insert text, and many more actions. ImageMagick is composed of a series of commands that allows the manipulation of image files. ![]()
