# define PHP_IMAGEMAGICK_VERSION_DEFS_H
// Q) Why are the defines done in this file?
//
// A) Checking whether an ImageMagick function is available _and_ usable is
// annoyingly difficult. It's pretty common for new functions to be introduced
// in patch releases, (e.g. 6.5.4-8) rather than in minor releases (6.5.5-0).
//
// Additionally, the api for new functions often changes quite rapidly in the
// first few versions it is available in, which means we can't just check for
// the presence of the symbol
//
// Because of those two things, the sanest thing to do is to support features
// based on the minimum minor version from which they are continually
// available and stable.
//
// Any mistake in which version is required for a feature can be fixed in a
// single place, rather than having to have duplicated info elsewhere.
