How to Save the Result of an Online Image Processing Task

Let's look at the required steps for online image processing using ImageMagick. First we need a form that takes user inputs, including text and image. By clicking on a submit button these inputs should be sent to another page where ImageMagick utilities and commands are waiting to do their task. What should we do One solution is to generate a random number for each submit action and use that number in the name of the image file generated by ImageMagick. The drawback is that the random numbers may be the same because it is possible that at the same time thousands of users press the submit button. Moreover, spending time checking for repeated numbers for each submit is not the optimum solution.

How to call Image Magick Command-line Utilities within PHP code

There are some commands in PHP that we can use for calling external executable files (like ImageMagick command-line utilities). So by passing an ImageMagick command as a parameter to these PHP functions we can do our request online. The simplest form of using this function with ImageMagick is using a parameterized command utility as a parameter in it. For example Look at this command. It is very important when calling an ImageMagick utility in an exec command to address the correct locations of the executable and the source and destination image files. In fact most errors when using ImageMagick online come from incorrect addressing. In the previous command we have to place a valid address of where we've installed ImageMagick instead of fullpathtoimagemagick. Moreover the absolute address of where we are going to read and write an image should be specified in fullpathtoimage placeholder. The better solution when using exec is to initialize some variables with the environment path of...

Image Magick -compress and -quality Options

Now let us see what capabilities ImageMagick offers for lossy and lossless compression. Here is the -compress option Don't worry about the right parameter for your image formats. If you don't use - compress option in your commands, ImageMagick simply chooses the appropriate compression scheme for it. That's why we skipped the - compress option in our previous workshops.

How to Define New Fonts for Image Magick

For Windows users all the True Type fonts installed on the system can be accessed by ImageMagick. As mentioned before you just need to know the right name of the font or the font family. But Linux users need to change some settings for activating new fonts. If you specify a font in your command, ImageMagick searches it in the font configuration file, type. xml. lib ImageMagick-6.2.4 MAGICK_FONT_PATH Sometimes we need to add and install a new True Type font (TTF) on ImageMagick if you are a Linux user. Here are the required steps for doing this. The new font should be ready to use now. Try the following command and see if it has been added to the ImageMagick default fonts

Practical Web Projects

Some of the most important uses of ImageMagick are its web capabilities and online image processing features. We can perform almost any command-line image handling on websites too. There are two ways for calling ImageMagick from a web page Installing command-line ImageMagick utilities on the server and using a PHP function like exec or system for running these utilities Please keep in mind this is not a PHP training book and we assume you have some basic knowledge about PHP and dynamic web programming. Installing and configuring ImageMagick on a Linux server has been described before. During this chapter we assume that you've installed it on your server correctly.

Identify, Display, and Import

In this chapter we will see some ImageMagick utilities that are a little different from the ones we have already studied. On the other hand, by referring to the previous workshops you'll see there is always at least one image processing function that has been performed during those workshops. We used convert, mogrify, compose, and montage for tasks like The utilities that will be introduced in this chapter are different because their main task is input output file management, and retrieving detailed info about images and ImageMagick environmental settings. In this chapter we will see how to use display for showing the result of any image processing on an X window and we will see how to capture image data from a part of the screen or a window with the help of import. Let's start with identify and learn how to retrieve useful information about images with this utility.

Compression versus Quality

In this appendix we will take a look at the options that ImageMagick has provided for them and some hints about the best way to select an image format for our work and compress it using a suitable algorithm. The goal of image compression is reducing the size of an image so it can be saved using less space and can be read faster especially when we are dealing with online image processing tasks. But it definitely has its costs. By compressing an image we reduce its quality. It is up to you as a user to choose the right format and compression scheme to achieve a good balance between quality and compression. Let us see what capabilities we can find in ImageMagick for handling these issues.

Online Image Water Marking

One of the most important usages of online image processing is watermarking. A watermark is a little sign or logo that is placed on an image to mark it as a copyrighted resource. This is a simple workshop that shows you how to place a watermark on an image with a single command call. In the code opposite we first get the input files that have been sent to our .php page using the post method and save them in some variables. The path to the composite utility is saved in a variable (as before) to make it easier to call the ImageMagick command-line utility.

What are the Valid Key-Value Pairs for MSL files?

Based on the current version of ImageMagick (it is 6.2.5 at the time of writing this chapter) there is a limit to the number of keys and values that we can use in MSL files. Adds charcoal effect to the current image as in the Charcoal option in ImageMagick. The radius defines the range and the Sigma sets the thickness of charcoal. Acts like ImageMagick emboss option. Acts like ImageMagick enhance option. Acts like ImageMagick equalize option. Acts like ImageMagick flip option. Acts like ImageMagick flop option. Acts like ImageMagick frame option. Acts like ImageMagick magnify option. Acts like ImageMagick minify option. Acts like ImageMagick normalize option. Acts like ImageMagick resize option. Acts like ImageMagick roll option. Acts like ImageMagick degrees option. Acts like ImageMagick sample option. Acts like ImageMagick scale option. Acts like ImageMagick sharpen option. Acts like ImageMagick shave option. Acts like ImageMagick shear option. Acts like ImageMagick Acts like...

An E-Card Application

In this chapter we will see how to use ImageMagick for creating them. But before starting please keep the following notes in mind ImageMagick or other graphic libraries and applications are just tools with some capabilities for creating various graphics like poster, e-cards, and so on. Familiarity with these packages is required but not enough. The more important factor is having good knowledge and creativity when it comes to selecting image, text, font, color, and any other artistic concept that may help in creating excellent and amazing artwork. Due to the subject of this book (ImageMagick) and our need for e-card elements like fonts and images we have to refer to some image and font websites. Moreover, we need to install downloaded fonts and define them for ImageMagick. I've introduced links to various websites offering free collections of fonts, animated GIFs, and images in Appendix A. The required steps for installing new fonts for ImageMagick are described in Appendix A. I would...

Building a Confirmation-Code

In this workshop we are going to design and develop a random confirmation-code box with the help of ImageMagick and PHP. This workshop has two main parts. The first part is a random string generator, which produces an alphanumeric string four to fifteen characters long. This generator will be completely developed in PHP. In the second part we pass the generated string to a function that calls ImageMagick for drawing each character with a specific font, size, position, rotation, and so on. The first part is the section where the initial ImageMagick parameters are called. The following code is generated in the first part

Composite Syntax and Options

There is an extra channel for images that have transparent features. We call this channel the matte channel. So in the previous workshops whenever we set the xc option to none, we in fact inform ImageMagick that any drawings or images in the current file will have to be placed on a transparent background. We set the background to transparent and hence, ImageMagick automatically creates a matte channel for our image. Black and white are not the only colors that ImageMagick uses for representing a matte channel. In fact it uses all the gray scale colors for it. The gray shades will be interpreted as semitransparent areas. So darker gray shades represent lesser transparency and lighter ones simulate more transparency.

Installation and Configuration

Like most other open-source applications, ImageMagick can be installed and configured on many platforms. In this chapter, we will discuss various installation processes and by the end of this chapter we will learn about Getting ImageMagick ImageMagick installation requirements Installing ImageMagick from a source Installing ImageMagick from a binary Installing ImageMagick on supported platforms like Where to get ImageMagick You can find many ImageMagick ftp and http download links on the Internet. But I suggest you download it from the original website, because the links in that site always lead you to the newest version of the program. Sometimes third-party websites update their links with a delay (unless they use the syndication solution for their download links). Moreover, during the lifetime of a released version there are often some bugs and enhancements that are issued by ImageMagick users and based on these reports, the development team of ImageMagick will make any required...

Mogrify Syntax and Options

Convert can save the image processing tasks in a new file but Mogrify overwrites them on the file that it is working on. Here is the syntax This is not the optimum manner of implementing this step but I have introduced it just for showing the several methods available for performing a task in ImageMagick.

How to Identify the Current Installed Fonts

Path C Program Name Family Style Stretch Weight As you can see, in the first part of this command output the default fonts, which are defined during the ImageMagick installation, are listed. We will see how to Don't use a family name as a font name in your commands or ImageMagick will use the default font. You need to replace every space between words of a font name with a - character. For example, the font anglo text should be referred as anglo-text in ImageMagick


In the earlier chapters, we learned that besides ImageMagick command-line utilities, there are several compilers and interpreters that we can use to accomplish custom image processing tasks. ImageMagick utilities have an internal interpreter called conjure that is suitable for users who don't have access to any compiler or interpreter. The conjure utility can process ImageMagick scripting code, which is known as MSL (Magick Scripting Language). This language is a variant of XML. As a matter of fact, every command and option is represented in the form of elements. We will study the MSL coding notations in this chapter. 1. First the customised image processing commands should be written in an MSL file. 3. ImageMagick processes these inputs and functions based on them. As we will learn there are only few parameters for the conjure utility and the MSL elements are limited too. This means that these concepts (Conjure and MSL) are in a very early stage in the ImageMagick engine. So maybe in...


In this chapter we have studied three new ImageMagick utilities We are now familiar with the -list option too, which is used to extract information about ImageMagick keywords and installed features. In the next chapter we will learn about animation techniques in ImageMagick.


ImageMagick Tricks Sven Henckel studied media informatics at the University for Practical Business Studies in Gutersloh, Germany. His diploma thesis was about the automatic generation of layout documents like QuarkXPress and Adobe InDesign. Before studying he worked as a developer and consultant for web applications. He currently works as an IT project manager for a European media service provider. He has developed a quality assurance system in which ImageMagick plays a very important role. Through the years he has attained specialized knowledge in the fields of Java, PHP, SQL, XML, and PDF. Moreover, he is interested in Open Source software, communication, and design. Gabe Schaffer has a degree in computer science from Case Western Reserve University in Cleveland, Ohio where he resides. He has been programming for over 20 years, has been doing photography for 10 years, and does both as a freelancer. He uses ImageMagick for automating digital photo labs.

This chapter deals with animation in ImageMagick. There are two ways of handling an animation. We can just show a number of still images in a directory with a predefined delay or we can make an animated file with them and show the result. The convert and display utilities are capable of making and showing animated files. Beside these utilities animate is specially developed for working on animations in ImageMagick.

Convert and Mogrify

We learned from Chapter 1 that any image processing activity in ImageMagick can be done using its utilities. The convert utility is one that contains many parameters for implementing more than seventy percent of ImageMagick features. We can see that mogrify is similar to convert in some situations. These utilities will be studied in depth in this chapter and we will get familiar with their image processing and other capabilities. We will concentrate on parameters and their practical usage. These are very important because we will see them being repeated for other ImageMagick utilities during the next chapters. As a matter of fact all of ImageMagick's functionality comes from about 200 options that may be used in several utilities. The question is, if the result is the same then what is the point of repeating the same options for different utilities Good question. In order to find out the answer we have to analyze the ImageMagick utilities' anatomy. So let's start our trip with this...


Identify is one of the special utilities in ImageMagick because, unlike other utilities, it works on image characteristics and specifications. There is a lot of helpful information that identify can retrieve from an image and display at the command line. well) that helps us to find out more information about the ImageMagick software installed on our machine. As you see the options of this utility are definitely less than those of other ImageMagick utilities. Hence, it seems that this one has been optimized just for informative purposes. Version ImageMagick 6.2.5 10 01 05 Q16 http www.imagemagick.org The -format option is the tool that we need to extract customized information that we want. The parameter of this option is an ImageMagick format string. You can find the complete list of these control characters in the previous chapter. How to Get Information about ImageMagick There is an option in ImageMagick that is also listed in the identify utility. It is -list and it can list...


The display utility is the basic ImageMagick program for showing images or image sequences (like all the .png files in a directory) on a X server. For ImageMagick users running Windows there is a corresponding utility called imdisplay.exe. However a v x this is a contributed application and was not developed by the ImageMagick development team. So it does not have the capability to receive command-line options and parameters for showing images. As you may note, this list of parameters is a subset of those of other popular ImageMagick utilities like convert or compose. However these options act differently when used with display. This tells ImageMagick to create an X window 200 pixels wide and 100 pixels high. These dimensions are smaller than the image size so unlike with the geometry function in other utilities here we will get horizontal and vertical scroll panes to move around the image in that window. In this form of call there is no need to use any extra option and the file will...


The last utility that we will examine is the simplest ImageMagick utility, which is used for comparing two images of the same size. When using compare, keep in mind that both images that are to be compared must be of the same size. Otherwise you'll get the following error message image size differs.


This is another useful ImageMagick utility that is used mainly for managing a group of image thumbnails and previews. Therefore, it has become the favorite utility of users who want to create and manage photo galleries. 3. It is hard to set a label for each image manually. We can use the ImageMagick format character strings instead. Given below is the complete list of format character strings montage -font tahoma -pointsize 65 -title 'My Art Works with ImageMagick' -pointsize 10 -label 'First row nname f nsize b Bytes' packt.png flag.png hafez.png -label 'Second row nname f ndimension hx w' c2i.png 3dbutton.png candy.png labeled_montage.jpg The - texture option has one parameter that sets the background texture for an image. Here I used a built-in ImageMagick pattern. However it is possible to set an image file as the background texture. In this way that image will be tiled across the background of framed thumbnails. You can find a complete list of ImageMagick patterns in Appendix A.

Performance and Caching

Think of the early days of the World Wide Web. Every print-advertising agency immediately became a web specialist megabyte-sized Photoshop graphics were exported and showed up like that on the web. When the creative director got complaints that the page took too long to load over a modem line, he or she perhaps only answered, Thepage loads pretty fast here. This was logical, because locally, a megabyte loads pretty quickly. It is, however, a completely different story over the Internet.

Using the if Statement to Control Program Flo^

Another alternative is to create the graphics yourself. Even if you don't have any artistic talent at all, modern software and technology make it quite easy to generate passable graphics. You can do a lot with a digital camera and a freeware graphics editor. Even if you hire a professional artist to do graphics for your program, you might still need to be able to sketch what you are looking for. This book's CD has a couple of very powerful freeware image-editing programs.

15.1 Introduction

With the assistance of the GD library, you can use PHP to create applications that use dynamic images to display stock quotes, reveal poll results, monitor system performance, and even create games. However it's not like using Photoshop or GIMP you can't draw a line by moving your mouse. Instead, you need to precisely specify a shape's type, size, and position.

Show A Little Class

Consider this fairly specific task Suppose you have some cleanup work that needs doing on directories that contain graphics. You need to remove deadwood, but before you can do so, you need to view the images. Rather than open each picture individually using an application such as Photoshop or GIMP, you want to open all the files at once in your browser. Not only do you want to see the image, you also want to note the filename of the image in case you decide to remove it.

GUI Applications

Most people think GUI applications are only for large, complicated tasks and require complex libraries that are only available for compiled languages such as C++ or Visual Basic .NET. This simply isn't true. GUI applications come in all sorts of different sizes and shapes. There are simple applications such as calculators and clocks, and there are complex applications such as Photoshop and PowerPoint. They also come in different languages, such as Java, C++, PHP and Python. Regardless of what they do or how they are written, GUI applications all share a common goal they represent tasks and data in a graphical way. Applications written in PHP-GTK are no different. They are written to make complicated tasks easier to manage and understand. Applications written with the PHP-GTK scripting language can be just as powerful as those written in compiled languages.

CI's Image Class

If you are allowing users to upload images to your site, you also need to look at CI's Image Manipulation class. This works with the three most popular image libraries for PHP GD GD2, NetPBM, and ImageMagick. (Use phpinfo() to find out which of these your server supports.) Image watermarking only works with GD GD2, though Which image library you are using. The default is GD2, so if you're not using that in your PHP installation, you would need to specify the one you are running, e.g., config 'image_library' 'ImageMagick' (You'd also have to supply a path to the ImageMagick library using

Setting Transparency

Most graphic editors, like The GIMP and Photoshop, allow you to create an image with transparent pixels built in. GdkPixbuf will respect transparent pixels that are built into an image file. However, it is sometime necessary to work with images that have been created without transparency. This doesn't present too much of a problem, because you can add transparency to any GdkPixbuf that doesn't have transparency already. You do this by creating an alpha channel for the GdkPixbuf. An alpha channel defines a particular color in an image to make transparent. The following line makes all white pixels in an image transparent

How It Works

The following code is where the actual image upload occurs. This part is rather similar to Chapter 6 in that you are loading the image-processing script into an invisible iframe to give users the feeling that everything is happening dynamically, without the page refreshing.
