C # convert Word to multiple formats (convert Word to XPS/SVG/EMF/EPUB/TIFF ),
A tool with powerful document conversion functions, wherever and whenever it is necessary in a modern office environment. In this article, we will continue to introduce the Word document Conversion Function (Word to XPS/SVG/EMF/EPUB/TIFF). W
C # how to convert a PDF file into multiple image file formats (Png/Bmp/Emf/Tiff ),
PDF is one of the most common document formats in our daily work and study, but it is often difficult to edit documents, it is annoying to edit the content of a PDF document or convert the file format. Generally, developers can choose to edit PDF documents or
On MSDN, we can see that using the Image: Save method of GDI + can easily Save images as BMP, GIF, TIFF, PNG, and JPEG formats. Although the Metafile class of GDI + allows us to read images in EMF and WMF formats, this class does not directly provide storage methods to write EMF, EXIF, and WMF files. This article introduces another clever writing method.
Use the Bitmap class of GDI + to create an object. A
Java.lang.Object in Java. EMF also generates an interface and implementation class for each model that corresponds to the factory and package. Where **factory inherits from Efactory, providing create*** methods for the creation of each class in the model. In Jstudio, the use of EMF to achieve business model object building and code generation, reduce the workload of developers, improve efficiency, and the
EMF query that we're going to introduce today is a subassembly of EMFT. We can use it to query the EMF model, which reduces the difficulty of dealing with complex models.
2 Establishing the Library model
In the article introducing EMF, the most common example is the Library sample. The UML diagram of the library model looks like this: (The Ecore model and sour
Friends who have been in touch with Eclipse for some time should have heard the name EMF, an acronym for the Eclipse Modeling Framework, an important subproject of eclipse, if translated into Chinese, is the Eclipse Modeling framework. It's really hard to determine what it's for, and I think that the EMF should have a certain understanding of model-driven development (MDA), and
The EMF (Eclipse Modeling Framework) Modeling framework can help us transform models (UML, XSD, etc.) into robust and rich Java code. Using EMF to build an application, not only can greatly improve the development efficiency, but also take advantage of the many features provided by EMF to ensure the robustness and perfection of the model, including model change n
Descriptive descriptions can be written at the same time when the EMF file is created using the createenhmetafile function;
You can use the getenhmetafiledescription function to read the description text of the EMF file.
The explanatory text in this example is very simple, but the format of the standard explanatory text should be:ProgramName #0 file title #0 #0
Unit unit1; interfaceuses windows
" relationship (generally in UML, the Black Diamond table is usedIf a class is not included in any other class, the instance of this class will not be saved to the file. In Example 2, category is included in shop, and product is included inCategory. In this way, all objects are directly or indirectly contained by shop objects. In other words, if shop is used as the "root", all objects can be saved to files.
EMF encapsulates Basic Java types and some
In an EMF-generated application, every command that a user makes can be revoked (undo), such as modifying the price of a product, pressing the Undo button to restore the original price, and, of course, Redo it back to the new price. To implement this function, the application maintains a stack-like data structure (Commandstack) for storing commands, and each executed command is stored there, removing the most recent command when it needs to be undone.
Applications generated by EMFProgramYou can undo each command. For example, if you change the product price, you can click the Undo button to restore the original price.To return to the new price through redo. In order to implement this function, the application maintains a commandstack data structure for storing commands.All the commands that have been run are stored there. You need to extract the most recent command to undo it. This data structure is maintained by the editingdomain object,Edit
customizable Java code. The standard format for the model definition used by EMF is XMI (XML Metadata Interchange), and there are four ways to convert the model you created to the XMI format:
Create a XMI document directly using a text or XML editor;
Export the model created using modeling tools such as Rational Rose to generate the XMI document;
Using a Java interface with model feature annotations;

GEF (Graphical Editor framework) is a graphical editing framework that allows developers to visually display and edit models to improve user experience. With GEF, you can easily implement XML editor, UML class diagram editor, and other applications.Program.
EMF (eclipse modelling framework) is an important part of the Model Driven Architecture of eclipse. It can convert models into efficient, correct, and
In EMF, you can use XML schema to define the model and then convert it to the genmodel model. However, after I load the fourth step of the genmodel wizard, an nullpointerexception is generated as follows, leading to the inability to continue:

Given a model, EMF can automatically generate Java source code-the source allows you to create, query, update, serialize, drag, validate, and track changes to your model instances. EMF provides a set of effective reflection APIs and allows you to work with a dynamic (not generated) model.
First, the introduction
The Eclipse Modeling Framework (EMF) is a Java op
-------- Thanks to the old man and Tao (this is called only the old man of the old man. Here, let me go, ), there is a good win. They are all cool people.
When I was just about to do this, I couldn't figure out where to start, even the EMF file and vector plot, and I didn't know what it was. The as plot function was useless at all, reading files in B/S mode is even more difficult. At that time, I thought about two directions:
The GEF design does not impose any restrictions on the model part. That is to say, we can construct our own model. The only thing we need to ensure is that the model has a message mechanism so that it can communicate with each other in the event of a change.GEF (through editpart ). In the previous examples, we used the propertychangesupport andPropertychangelistener is used to implement the message mechanism. Here we will introduce how to make the model constructed by GEF using

The creation of EMF by Rational Rose is more intuitive than that of XSD and Java Bean, and more in line with the "design state ". In some important applications, we often see EMF models created by Rational Rose, such as EMF itself, UML2, WTP, and DTP.
Rational Rose has many versions. I use 7.0.0.4-ifix02, which is basically compatible with common
