Selection.Export Method (Visio)
Exports an object from Microsoft Visio to a file format such as .bmp, .dib, .dwg, .dxf, .emf, .emz, .gif, .htm, .jpg, .png, .svg, .svgz, .tif, or .wmf.
The file name extension indicates which export filter to use. If the filter is not installed, the Export method returns a compiler error in your Visual Basic or VBA project. The Export method uses the default preference settings for the specified filter and does not prompt the user for non-default arguments.
The Export method of a Page object supports saving to HTML file format using the extension .htm or .html. When pages are exported, Visio uses the settings that were last selected in the Save As dialog box.
If the specified file already exists, Visio replaces it without prompting the user.
Starting with Microsoft Visio 2010, you can use various properties and methods of the ApplicationSettings object that relate to raster images to configure settings for export to .bmp, .gif, .jpg, .png, and .tif file types.
