![]() I spent a lot of time reverse-engineering the format. GDI+ drawing records are entirely different in format than normal EMF records, but allow a lot more features.Īt the time I wrote my code, all I had to go on for WMF and EMF were the MSDN docs, which were kind of confusing at times, and EMF+ was not documented at all (although there were unofficial docs for some of what I needed). Supports curves and (almost) everything else GDI allows WMF: from the 16-bit windows days - doesn't support curves (bezier, cardinal, etc) and various other GDI features.All you need is Quantum GIS and Inkscape, both open-source software. The further development EMF has a greater color depth than the predecessor format. The PSD file type is a format that is only used in image editing. It is also possible to create animations and videos. You can export a representation of that shapefile data (using features styles and labels) as EMF. The format has low compatibility but can be converted directly to other formats (raster and vector graphics). It was quite a bit of work but the results were very good. You can't actually convert the shapefile in EMF, since shapefile data is composed by geometric features and related attributes. To do so, choose your traced photo and click the enlarge option at the top of the window. File constants associated with this file format are. They can be read and written as vector images in the Document and Medical Imaging toolkits. EMF/WMF Vector files can be read and written as raster images in the Imaging Pro toolkits. ![]() ![]() To complete vectorizing your image, youll need to separate these color groups from altering them. The Windows Metafile (WMF and EMF) formats are vector formats that may or may not also contain a raster image. Rescaling degrades a picture symbol that uses a BMP file. I found that I had to use Graphics.EnumerateMetafile(), and in the callback I manually extracted the data from each record and interpreted each record type individually. Your image has now been organized into colored shapes corresponding to the original raster image. So BMP and EMF raster files are best used at the scale that they were created for (figure 14), and an EMF vector file is the better choice if you want to use a picture marker symbol for graduated symbols or if you change the size of the symbol in ArcMap (figure 15). There is no GDI+ method or set of methods to turn a metafile into a graphics path. In my case, I created a converter to convert records from WMF, EMF, and EMF+ metafiles to vector graphics objects. ![]()
