Detailed information and examples are available for each script on separate pages linked above and below as well as a summary list of them all. You can also try many of them in an interactive environment at JqMagic. This is a collaborative effort with Jd Audibert. To download a script, go the examples page for that script and simply click on the link. The links are controlled by a counter script and are set to download automatically upon a single left button click. These scripts are bash unix shell scripts and should work on Linux and Mac OSX with IM 6.3.5.0 or higher. Pointers for use: Be sure you have installed the unix calculator, bc. It is an option that you may have to select when installing unix. Download the script Change the name to add or remove the .sh as desired when running Set the script to executable (chmod u+x) Find the full path to where IM (convert) resides by typing in a shell terminal window: type -a convert If type -a convert returns more than one path, type in a shell terminal window: path2/convert -version, where path2 is each of the paths found. Decide which version of IM you want to use. Modify your PATH environment variable so that it includes the full path to where IM (convert) resides (often /usr/bin or /usr/local/bin). This can be done by editing your .profile file. Alternately, edit the script somewhere between the comments and the first use of any IM command, such as just below the defaults section to add the following two lines: imdir="path2" #(such as imdir="/usr/local/bin" or imdir="/usr/bin") PATH="${imdir}:${PATH}" Open a shell terminal window bash /fullpathto/scriptname(.sh) arguments /fullpathto/inputimage /fullpathto/outputimage To avoid the bash and just use scriptname(.sh) ... set your PATH to contain the location of the script Optionally edit the script to change the default directory (found after the defaults section) from dir="." to dir="/tmp" If you have trouble with filenames with spaces in them, then you will need to edit the script in several places until I have time to review and fix all my scripts. Find where infile and outfile (maskfile or any others) are defined at the end of the argument trapping section. Make sure to enclose in double quotes any declarations of those files that include $1, $2, etc, such as infile="$1", etc Find any occurrences of $infile or $outfile and enclose them in double quotes as "$infile", etc. These scripts can be used with PHP exec command.

A very detailed description of Cygwin installation, relevant script syntax and examples has been provided by user snibgo on his web site at http://im.snibgo.com/cygwin.htm. A brief outline that he wrote can be found at http://www.imagemagick.org/discourse-server/viewtopic.php?f=26&t=25910&start=30#p113836. Many thanks to snibgo for this excellent document. Another guide to using bash shell scripts under Cygwin on Windows has been provided by Wolfgang Hugemann in his excellent page, Usage Under Windows My earliest scripts were developed under ImageMagick-6.3.5.0 on Mac OS 10.4x. I have tried to keep them updated with changes in IM versions. All were developed using Q16 IM. I do not know how compatible they are to older version of ImageMagick, nor to other Q levels or other versions of Unix. NOTE: Starting with IM 6.3.5.7, -matte/+matte were deprecated in favor of -alpha set or on/-alpha off. Therefore, many of my scripts may not work with IM versions prior to that unless replaced with the deprecated syntax. Use at your own risk. The argument testing may not be foolproof nor do I bear any responsibility for any problems that may occur by their use. I would like to thank Anthony Thyssen for his patience with all my newbie questions about IM and Unix. His replies were invaluable. My background involves image processing with a specialty in image perspective transformations from arial photography. For details, see my personal information page. I have also written a digital image filtering tutorial (2MB PDF). It supplements the description of the following scripts below with more mathematical detail: binomial, derivative, gradient, laplacian, statsfilt, isonoise, sharp and space. And I have created a tutorial for Fourier Transform Processing With ImageMagick. It supplements the description of the following scripts below with more mathematical detail: spectrum, fftconvol, fftdeconvol, fftfilter, cepstrum, camerablur, cameradeblur, normcrosscorr and notch. Also see my ImageMagick Tidbits pages. Comments and bug reports are always welcome. My contact information is fmw at alink dot net If you find any of these scripts are particularly useful, please let the folks at ImageMagick know. Perhaps they will consent to implement them as IM functions. NOTE: I fix problems that I find with the scripts or make improvements often. So please check the last modified dates below or the revision dates in the scripts for updates.
