2025-8-31 : Update readme. ---   DCWriterLite is an open-source structured document editor similar to RTF, which can benefit many different groups of people: ## For C# Developers   It demonstrates the following amazing programming techniques: 1. Utilizing `System.Drawing.Graphics` and `System.Windows.Forms.Control` types in Blazor WebAssembly development. This helps developers migrate a large amount of C# code that would otherwise be discarded to WASM development, protecting the industry's investments in related fields. 2. It implements a complete DOM model in the most concise way possible, making it easy to learn and understand. While [Open Office](https://www.openoffice.org/) also defines a similar DOM model, but it contains tens of millions of lines of source code, which exceeds the comprehension ability of most individuals or teams. 3. This project shows how to trimming the Blazor WebAssembly framework. This helps developers understand part of the underlying principles of Blazor WebAssembly, reduce the size of the final software file (dotnet.wasm), and improve software loading speed. ## For B2B Developers 1. It provides distinctive structured document functions. It supports free text input and also offers form areas to restrict the input methods for specific regions. 2. It implements a custom DOM model, which provides unlimited extensibility. Developers can create new document element types based on this, making the software more in line with specific business requirements. For example, developers can use it to build template creation tools to dynamically define various complex form interfaces required for user business. 3. Instead of being based on HTML DOM, DCWriterLite implements its own document **layout** algorithm, which breaks through some technical limitations of HTML DOM. For instance, it achieves a reliable Undo/Redo function and ensures completely consistent **layout** results across different browsers. 4. It uses XML format for storage, featuring a simple structure. This allows developers to easily develop backend programs to process millions of documents in batches without calling the DCWriterLite software module. ## For Web Developers   DCWriterLite offers the following user-friendly features: 1. It is a pure front-end component that does not depend on third-party components and supports mainstream browsers such as Chrome and Firefox. 2. It supports real-time pagination, full WYSIWYG (What You See Is What You Get) functionality, achieves completely consistent typesetting effects across different browsers, and offers reliable Undo/Redo operations. 3. It supports multiple operating systems including Windows, Linux, Mac, Android, and iOS. 4. It provides a very concise API (Application Programming Interface) that allows for easy implementation of the multi-document mode with pagination tabs. # For Electronic Medical Record Developers   DCWriterLite offers very professional features related to clinical medical documentation: 1. Structured medical record documentation functionality. 2. Capable of implementing medical record front pages, admission records, nursing records, progress notes, surgical records, informed consent forms, discharge summaries, examination reports, and imaging reports. 3. The commercial version also provides writing trace retention, multi-level permission control, and various medical expressions such as dental charts and menstrual history. It can also automatically calculate the scores of rating scales. 4. In China, this editor software is already running in at least 50,000 hospitals, and it is estimated that 500,000 doctors use the software every day to write more than 10 million pages of medical records. 5.

[Function Demo Video: AI Assists Doctors in Writing Medical Records - 2](https://www.facebook.com/chinanjyyf.chinanjyyf.5/videos/1716579789030019) ## For Chinese Developers   DCWriterLite has passed the official certification of domestic operating systems such as Kylin, Foundersoft, and Tongxin, complying with the requirements of the Xin Chuang. ## For End Users   DCWriterLite provides simple yet powerful document editing functions: 1. It offers a user experience similar to MS Word, allowing users to get started without learning. 2. It supports accurate real-time pagination, realizes the What-You-See-Is-What-You-Get (WYSIWYG) function, and enables unlimited Undo/Redo operations, helping users achieve their goals quickly. 3. It provides multiple functions such as tables and header table rows, facilitating the rapid creation of documents with complex **layout**. ## Applicable Application Scenarios 1. Structured Electronic Medical Record (EMR) Systems: Assisting doctors in writing medical record homepages, admission records, progress notes, inspection and test reports, nursing records, patient informed consent forms, discharge records, etc. 2. Government Electronic Official Document Systems: Helping users define various official documents and dynamically adjust the content and status of official documents according to business processes. 3. Financial Business Compliance Document Processing: Its unique structured document technology makes it easier for the system to extract key data from documents for inspection and maintenance. 4. Manufacturing Industry Form Systems: Enabling the rapid definition of complex form input interfaces, helping the manufacturing industry input various complex node data one by one, and facilitating quick reading and analysis by the backend. # Screen snapshort
