octave高画质图像处理字节数限制问

来源：互联网发布：常见面试算法题编辑：程序博客网时间：2024/05/18 02:40

在用octave进行高质量图像（raw, tif图像等）处理时，出现了字节数限制的警告。

warning: your version of GraphicsMagick limits images to 16 bits per pixel

问题的解决方法是重装graphicsmagick并且制定32比特，命令如下：

brew reinstall graphicsmagick --with-quantum-depth-32

但是

之后在运行图像处理相关的代码时出现了一下错误：

error: default_formats: /usr/local/Cellar/octave/4.0.2_4/lib/octave/4.0.2/oct/x86_64-apple-darwin15.5.0/__magick_read__.oct: failed to load: dlopen(/usr/local/Cellar/octave/4.0.2_4/lib/octave/4.0.2/oct/x86_64-apple-darwin15.5.0/__magick_read__.oct, 2): Symbol not found: ZN6Magick5ColorC1Ettt

问题正在解决中。。。
