据我所知，如果您只使用默认的cropvariant，则不需要告诉 f:image ViewHelper 任何有关裁剪的信息.但是我在 Mittwald 托管的网站上遇到了一些问题 - 那里的 GraphicsMagick 版本无法以某种方式进行裁剪(在其他 Mittwald 托管网站上，它使用相同的 GM 版本).所以我只是在前端裁剪有问题的网站上切换到 ImageMagick，然后它就起作用了.如果 GM 和裁剪有问题，默认的内容元素甚至不会在后端预览中显示裁剪的变体(文本和媒体元素)

As I know you dont need to tell the f:image ViewHelper anything about the cropping if you only use the default cropvariant. But I had some problems with Mittwald hosted websites - the GraphicsMagick version there was not able to crop somehow (on other Mittwald hosted sites it worked witht the same GM version). So I just switched to ImageMagick on the sites which had problems with cropping in the frontend and then it worked. If there is a problem with GM and cropping, default Content Elements won't even show the cropped variant in backend preview (Text and Media Elements)
