Imagemagick无法读取tif文件

Question

我刚安装了imagemagick for php with tiff support（--with-tiff = yes选项已用于配置）：

identify -list format | grep TIFF
  EPT  rw-   Encapsulated PostScript with TIFF preview
  EPT2  rw-   Encapsulated PostScript Level II with TIFF preview
  EPT3  rw+   Encapsulated PostScript Level III with TIFF preview
  PTIF* rw+   Pyramid encoded TIFF
  TIFF* rw+   Tagged Image File Format (LIBTIFF, Version 4.0.3)
 TIFF64* rw-   Tagged Image File Format (64-bit) (LIBTIFF, Version 4.0.3)

但是当我尝试加载tif图像时，我收到以下错误：

no decode delegate for this image format `' @ error/constitute.c/ReadImage/501 File: /var/www/test.php, Line: 44 Trace:

我可以在我的本地电脑上加载文件并打开它 - 工作正常。 有什么想法吗？
