+
+## Technical Details
+
+The technical focus of the File Manager preview feature is on the breadth of file type support and preview performance.
+
+The breadth of file type support requires special parsing and processing of some of them due to the large number of file types and different data formats in modern operating systems. For performance issues, since large text and long audio and video are common in file manager scenarios, memory consumption and asynchronous issues need to be taken into account when designing their data parsing.
+
+### Complex format document parsing
+
+For documents like PDF, doc/docx, rtf, we want to implement their preview not as images, but as text data so that their content can be quickly selected and copied. In Peony today, PDFs are previewed by generating images via poppler, and there are many libraries like pdf.js in web browsing services that provide text parsing support for such files. Further, you can consider using the node.js ecosystem combined with Qt WebEngine to further do these tasks.

+## 技术细节
+
+文件管理器预览特性的技术关注点在于文件类型支持广度与预览性能。
+
+对于文件类型支持的广度，由于现代操作系统中文件类型繁多，而且数据格式大相迳庭，需要对其中的一部分作出特殊的解析与处理。对于性能问题，由于文件管理器的使用场景中常见大文本、长时长音视频，在设计它们的数据解析时，需要考虑到内存占用以及异步问题。
+
+### 复杂格式文档解析
+
+对于 PDF、doc/docx、rtf 这类文件，我们希望在实现其预览时并非以解析成图片的形式来进行预览内容的展示，而是将其转成文本数据以便可以快速对它们的内容进行选择和复制。在现在的 Peony 中，预览 PDF 便是通过 poppler 生成图片来进行，在网页浏览服务中，有许多类似 pdf.js 这样的库是提供了这类文件文本解析支持的。进一步的，可以考虑使用 node.js 的现成生态结合 Qt WebEngine 来进一步的做这些工作。
