Before we get to the text of the license, lets just review what the license says in simple terms: It allows you to: * freely download and use ImageMagick software, in whole or in part, for personal, company internal, or commercial purposes; * use ImageMagick software in packages or distributions that you create; * link against a library under a different license; * link code under a different license against a library under this license; * merge code into a work under a different license; * extend patent grants to any code using code under this license; * and extend patent protection. It forbids you to: * redistribute any piece of ImageMagick-originated software without proper attribution; * use any marks owned by ImageMagick Studio LLC in any way that might state or imply that ImageMagick Studio LLC endorses your distribution; * use any marks owned by ImageMagick Studio LLC in any way that might state or imply that you created the ImageMagick software in question. It requires you to: * include a copy of the license in any redistribution you may make that includes ImageMagick software; * provide clear attribution to ImageMagick Studio LLC for any distributions that include ImageMagick software. It does not require you to: * include the source of the ImageMagick software itself, or of any modifications you may have made to it, in any redistribution you may assemble that includes it; * submit changes that you make to the software back to the ImageMagick Studio LLC (though such feedback is encouraged). A few other clarifications include: * ImageMagick is freely available without charge; * you may include ImageMagick on a DVD as long as you comply with the terms of the license; * you can give modified code away for free or sell it under the terms of the ImageMagick license or distribute the result under a different license, but you need to acknowledge the use of the ImageMagick software; * the license is compatible with the GPL V3. * when exporting the ImageMagick software, review its export classification.
