Imagemagick 从IFF和EXR格式到JPEG格式的图像转换

imagemagick

Imagemagick 从IFF和EXR格式到JPEG格式的图像转换,imagemagick,imagemagick-convert,Imagemagick,Imagemagick Convert,我正在使用convert Desktop/iff_image.iff Desktop/iff_image.jpg将我的图像转换为JPEG格式 但是 convert: no decode delegate for this image format `Desktop/iff_image.iff' @ error/constitute.c/ReadImage/552. convert: no images defined `Desktop/iff_image.jpg' @ error/convert

我正在使用
convert Desktop/iff_image.iff Desktop/iff_image.jpg
将我的图像转换为JPEG格式

但是

convert: no decode delegate for this image format `Desktop/iff_image.iff' @ error/constitute.c/ReadImage/552.
convert: no images defined `Desktop/iff_image.jpg' @ error/convert.c/ConvertImageCommand/3127.
对于.tif、.tiff、.cin、.dpx扩展，它工作正常

这个问题只针对.iff和.exr扩展。

iff 我不熟悉名为“IFF”的格式。很抱歉对这件事没有帮助

EXR 要支持读取和写入EXR格式，您的ImageMagick安装需要具有

  • …访问库（也必须安装在您的系统上）
  • …是在支持OpenEXR委托的情况下构建的
    • 在ImageMagick中，“委托”是支持ImageMagick处理其自身无法处理的格式的外部程序或辅助工具

    ImageMagick中最常见的委托之一是Ghostscript。处理PDF或PostScript输入文件需要Ghostscript，因为ImageMagick只能处理光栅格式。因此，Ghostscript代表ImageMagick将PDF和PS转换为光栅图像，然后将这些光栅数据交给IM，IM将完成其余所需的工作

    要打印所有内置委托的列表，请运行以下命令（在Linux或Mac OS X上）：

    相应的Windows命令是：

    convert -version | findstr Delegates
    我在系统上看到的该命令的输出如下：

    Delegates (built-in): bzlib cairo djvu fftw fontconfig freetype gslib gvc jbig \
                      jng jp2 jpeg lcms lqr ltdl lzma openexr pangocairo png   \
                      ps rsvg tiff webp wmf x xml zlib
    受支持的代理列表中应包含
    openexr
    。如果没有，则需要安装一个版本的ImageMagick

    要检查哪些编译时选项已用于生成您的ImageMagick版本，请运行

     convert -list configure
    如果
    委托
    未列出
    openexr
    ，则系统的二进制软件包未考虑openexr。如果它已列出，但仍不起作用，则说明其他问题

    在我的系统上，我看到：
