形态学使用Magick ++ [英] morphology using Magick++

问题描述

我正在尝试使用Magick ++从我正在编写的c ++程序中执行形态学。我找不到如何使用c ++中的形态学方法。

I'm trying to perform morphology using Magick++ from a c++ program that I am writing. I can't find how to use the Morphology methods from c++ though.

我正在尝试执行以下操作（我们从perl转换）：

I am trying to perform the following (we are converting from perl):

$q=Image::Magick->new;
$q->Read("blah.jpg");
$q->Morphology(method => 'Close', kernel => 'Diamond:4');

这不能用Magick ++完成吗？

Can this not be done with just Magick++ ?

我找到了这个网站，
http：//www.imagemagick。 org / api / MagickCore / morphology_8h.html ，
但我不确定这是否只是ImageMagick本身的源代码。

I have found this site, http://www.imagemagick.org/api/MagickCore/morphology_8h.html , but I am not sure if this is just the source code of ImageMagick itself.

推荐答案

似乎Magick ++没有能力做形态学。相反，必须使用MagickCore库调用（这意味着你不能再使用Magick ++类）：

It seems that Magick++ doesn't have the ability to do Morphology. Instead, the MagickCore library calls must be used (which means that you can't use the Magick++ classes anymore):

ExceptionInfo *e;
ImageInfo *ii;
Image *i;

e = AcquireExceptionInfo();
ii = CloneImageInfo((ImageInfo *) NULL);

strcpy(ii->filename, vm["input"].as<string>().c_str());
i = ReadImage(ii, e);
i = MorphologyImage(i, CloseMorphology, 3, AcquireKernelInfo("Diamond:4"), e);

它更复杂，并且没有像Magick ++那样的错误处理，但它有效。

It is more complicated, and there isn't any error handling like in Magick++, but it works.

要查看MagickCore库中的所有内容，请查看此处： http://www.imagemagick.org/api/MagickCore/index.html
