在哪里可以找到使用TMetafile和TMetafileCanvas的文档和/或示例？ [英] Where can I find documentation and/or examples of working with TMetafile and TMetafileCanvas?

问题描述

在努力向应用程序添加自定义打印时，我决定使用TMetafile创建页面，然后使用它预览和/或打印，但是我发现缺少文档。

是否有足够的资源来学习使用TMetafile和TMetafileCanvas的来龙去脉？

解决方案

从TMTMFile / Canvas的使用经验来看，与TMetaFile和TMetaFileCanvas的实现相比，与TMetaFile / Canvas的使用的来龙去脉与元文件的关系更大。也就是，您应该寻找有关EMF（或WMF）如何工作的信息。据我了解，Delphi的实现只是调用Windows来完成所有事情。

您可能希望更具体地了解所需的内容，尽管本指南没有完整的介绍。怎么做。

As I'm working to add custom printing to my application, I've settled on using TMetafile to create the pages, then using it to preview &/or print, but I'm finding the documentation lacking.

Are there any good resources for learning the ins and outs of working with TMetafile and TMetafileCanvas?

解决方案

The ins and outs of working with TMetaFile/Canvas are more related to meta files than to the TMetaFile and TMetaFileCanvas implementations from my traumatic experience of working with it. Aka, you should rather look for information on how EMF (or WMF) works. The Delphi implementation simply calls windows to do everything as I understand it.

You may wish to be more specific what it is you need to know though beyond a walk through guide on how to do it.
