WMF to Base64String

sunsher

Hi, Is it possible to convert a .wmf file to Base64String? Thanks

Yes: all files are just a stream of byte values - it's the interpretation that software puts on the internal format of those bytes that makes it a "WMF" or "JPG" file. The extension just indicates what format the software should look for.

string base64 = Convert.ToBase64String(file.ReadAllBytes(@"D:\Temp\myPicture.wmf"));

However, that doesn't mean that whatever you pass the base64 string to can do anything useful with it. For example, not all browsers support WMF file data in any format, and changing it to Base64 will not fix that. WMF is pretty much a "Windows only" image format: you would probably be better off using a more generic format such as JPG, GIF, or PNG.

I more concern. ;P I want the metafile to be created in memory rather than saving to a disk. It should be a blank metafile. I assume it is like this.

metfile = New Metafile(hdc, EmfType.EmfPlusDual)
