imagemagick - Manipulate one image into several

Question

I'm working with the Magick++ API and I'm trying to figure out how do I read in one image, and perform two different kinds of effects and save each out into a different image. Right now what I'm doing is reading in an image and warp/distort it along a circle path and saving that new one (image-warped.ext). This works great. My next step now is to also create another image that's a mirror flop. So read in a 400x400 pixel image, flop it along the right edge so I end up with an image that's 800x400 and then save that out.

How do I do that with the same original image object I just read in? I can't imaging having to go back and reread the original image again, after all it's already in memory. Or am I mistaken?

Thanks!

Answer 1

发现我可以简单地通过它：

Magick::Image originalFile;
originalFile.read("file.png");

Magick::Image clonedFile = originalFile;

此时我有 originalFile 和 clonedFile。我可以分别对待每一个。

我认为您正在寻找 CloneImage() 函数。读入，克隆它，处理一个并输出，然后处理克隆。

这也是命令行工具的工作方式……见这里。
