使用Octave处理raw或tif等高质量图像时遇到16位像素限制警告，通过重新安装GraphicsMagick并指定32量子深度解决了问题。然而，之后运行代码时出现错误，提示找不到符号，可能与GraphicsMagick库的版本或加载有关，目前问题还在解决中。

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：
