delegates - ImageMagick 不会将 Ghostscipt 显示为委托(delegate)

Question

试图让 ImageMagick 在 OSX Lion 中使用 MacPorts 与 Ghostscript 对话，但它没有。以前在 Snow Leopard 下运行良好，但在迁移助手期间出现问题。

无论如何，已经取消了所有 Mac 端口，现在正在尝试使用 Homebrew

已安装 Homebrew、ImageMagick 和 ghostscript。 Imagemagick 工作正常(使用 php 图像脚本和 MAMP)，但 Ghostscript 没有将 PDF 转换为 jpg。我可以看到，'gs' 没有被列为 Imagemagick 的委托(delegate)。

以下是一些相关的终端转储:

如何强制 Ghostscript 被 ImageMagick 视为委托(delegate)？

 

Answer 1

嗯，在来自 convert -list delegate 的列表中，有以下六行:

eps<=>ps     "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pswrite" "-sOutputFile=%o" "-f%i"
eps<=>pdf    "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 "-sDEVICE=pdfwrite" "-sOutputFile=%o" "-f%i"
pdf<=>eps    "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=epswrite" "-sOutputFile=%o" "-f%i"
pdf<=>ps     "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pswrite" "-sOutputFile=%o" "-f%i"
 ps<=>eps    "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=epswrite" "-sOutputFile=%o" "-f%i"
 ps<=>pdf    "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pdfwrite" "-sOutputFile=%o" "-f%i"

他们都确实提到了"gs"...

但是，您说您首先安装了 ImageMagick，然后才安装了 Ghostscript。

所以 ImageMagick 在编译期间找不到任何 Ghostscript，这就是为什么它没有出现在 convert -list configure | grep DELEG....

您应该尝试按相反的顺序安装:首先 Ghostscript，然后是 ImageMagick....
