我的 Imagemagick

Version: ImageMagick 6.7.1-7 2012-06-18 Q16

Answer 1

BC 是一个计算器/数学程序，我认为它没有安装在您的服务器上。您可以要求您的主机安装它。

我认为这与您之前的帖子有关，并且使用 Freds 代码执行的操作可以在 Imagemagick 中完成，无论如何您需要计算出您想要的内容，并且可以使用标准 php 函数而不是 bc 来执行计算.

Answer 2

尝试安装 bc：http://linux.about.com/od/commands/l/blcmdl1_bc.htm

（请注意，我假设您使用的是某种 *nix 风格）。
