我一直在尝试将tif图像转换为eps图像，保持原始分辨率数天。但没有成功。问题是无论在输入文件之前还是之后使用密度和调整大小命令，imagemagick总是将eps图像的分辨率设置为72 dpi。
The input file可以下载，例如我尝试使用imagemagick命令（所有这些都没有理想的结果）：
convert -density 300 input.TIF -profile "ISOcoated_v2_eci.icc" eps3:output.EPS
convert -density 300 input.TIF -profile "ISOcoated_v2_eci.icc" -geometry 2835x3780 eps3:output.eps
convert -density 300 input.TIF -profile "ISOcoated_v2_eci.icc" -resize 2835x3780 eps3:output.eps
我的转换有什么问题？我只需要输出eps图像，分辨率为300 dpi作为输入tif文件。 补充：识别output.eps
