Windows Metafile WMF/EMF Export is really wanted

Question

Hallo,

i wish to revive a situation with WMF/EMF Export from plantuml. It is sufficient Information about WMF facilty in Java domain on internet

Lot of very popular apps such as MathMagic, MathType, Illustrator, Xara Designer, Corel apps etc. have a metafile feature. The biggest goal of metafile is a scalability! Additionaly it is possible to transfer 2D in 3D (for example Xara 3D Maker). I wrote Metafile handling in C/C++. It was really not so difficult.

Best regards

What about converting SVG to WMF? See: https://stackoverflow.com/questions/31748727/how-to-convert-an-svg-file-to-wmf-format

I suppose you can do that entirely on the command-line, without launching the Inkscape GUI.

It is a bad way. After implementation of hidden I/O pipe over clipboard (Text to BMP) and using of JNI in C++ parent app no more command-line or shellexecute needed! Instead 2 or more seconds for processing of some UML input and rendering inside of plantuml and transfer of image in parent app i have only 0.02 sec for the same!!! But for clear and nice representation of UML output in text processing systems a DPI feature can be used but in final documents it must be scaled to fit in the page width. And scaling of pixels brings always an aliasing problem. This is not necessary for metafiles. And finally not all text processing apps have a SVG facility. Until now the leading companies for Mathematical Formulas prefer to use metafile standard and not SVG!

We really need help here. Generating WMF/EMF files from Java is not that easy.

One issue with FreeHEP is that it's only available under LGPL, and it looks quite old (Last Published: 2013-04-05).

For EPS and SVG we have built our own generators (see https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/eps/EpsGraphics.java or https://github.com/plantuml/plantuml/blob/master/src/net/sourceforge/plantuml/eps/EpsGraphics.java )

Let's start by something very simple : could someone provide us a Java code snipset that draw a simple rectangle and export it to WWF/EMF ?

Yea! No problem with this. I hope that brings nice results. May be i will take a look on converted java code. Anyway 30 years experience in programming...

Additionally i have compiled C# project just for check - is everything here? All is OK!
Take a look and test

Ok, thanks.
We have imported code here https://github.com/plantuml/wmf
The Java generated code is pretty well commented.

Maybe you could also convert/translate the following file:
https://github.com/papnkukn/wmf/blob/master/sample/Program.cs
and add it to the project.

I got "File has expired and does not exist anymore on this server",  any other place could find it?
