Upload this file to your server and call it ImageMagick.php or something then run it. This found all versions on my Godaddy hosting. Try this one-shot solution that should figure out where ImageMagick is, if you have access to it. * Draw the ImagickDraw on to the canvas */ newImage (1, 1, new ImagickPixel ('ffffff')) image->setImageFormat ('png') pngData image->getImagesBlob () echo strpos.* Create a new canvas object and a white image */ To test only the IMagick PHP extension (not the full ImageMagick suite), save the following as a PHP file (testImagick.php) and then run it from console: php testImagick.php. * Use the pattern called "gradient" as the fill */ * Composite the gradient on the pattern */ * Start a new pattern called "gradient" */ If I want to know if imagemagick is installed and actually working as a php extension, I paste this snippet into a web accessible file newPseudoImage(50, 50, "gradient:red-black") 5.EDIT: The info and script below only applies to iMagick class - which is not added by default with ImageMagick!!! For a much more detailed verification of whether the PHP module was installed correctly, use the phpinfo () method. If the installation was successful, the output of the command will simply show one line, and it will only contain the name of the module imagick. You could build ImageMagick by yourself, but it requires a build tool chain like Visual Studio to compile it. However, using the â resize options we have covered, it is, of course, perfectly feasible to enlarge our image. Run the following command to verify the installation. To conclude this section, typically, the most common way to change the size of an image is to shrink it to fit the desired size. Consequently, the actual scale may not exactly match the scaling factor we provide, but it will be very close. Most of the servers do have imagemagick installed at s /usr/bin/convert. You can also check if it's installed by running 'which convert' command on a linux/macOS and 'where convert' on windows. If ImageMagick is installed, it will return the version number. Fire the following at the shell: which convert. Open a terminal or command prompt and type 'convert -version'. This will scale the image by the amount specified: convert flower_original.jpeg -resize 50% half_flower.jpegįor most of us, this type of scaling will be perfectly fine, but we should note that the final pixel size of the image will be rounded to the nearest integer. How to check the Imagemagick path Login to your server as root. ImageMagick builds on a variety of Unix and Unix-like operating systems including Linux, Solaris, FreeBSD, Mac OS X, and others. Optionaly run more in-depth installation check. Take a note of the version number generated by the identify command. Execute the indentify command to confirm the installed version: identify -version. Similarly, we can also specify a percentage value when using the resize option. Now, we are ready to check the ImageMagick installation. In this example, we fit our original flower image into a smaller square box 64Ã64 pixels in size: We can build on the previous example by using the -resize option of the convert command: convert flower_original.jpeg -resize 64å4 flower_64å4.jpeg Another typical operation is image resizing.
