Image Conversion in C#

[Dilmurat Sulayman]

Hi,

I have a jpg image. Now, I'm going to put some text and merge it with other
emf file. So, I converted it to emf file with Image.Save. but I couldn't
load it.

My code is:

Image imgFile = Image.FromFile("test.jpg");
imgFile.Save("test.emf"), ImageFormat.Emf);
Metafile Img1 = (Metafile)Image.FromFile( "test.emf" );

and it gives me following error on the latest line.

Exception Details: System.Runtime.InteropServices.ExternalException: A
generic error occurred in GDI+.

have any idia on it?

Thanks,

Dil

There's about 1000 reasons what that happens.

Make sure you have write privledges to the directory. That one gets
overlooked alot.

I doubt thats your issue.

Hi Dil,

There's a syntax error in the second line. I was able to create the emf file
like this:

System.Drawing.Image imgFile =
System.Drawing.Image.FromFile(Server.MapPath("test .jpg"));
imgFile.Save(Server.MapPath("test.emf"),
System.Drawing.Imaging.ImageFormat.Emf);
*However*, did you see this?

"When you use the Save method to save a graphic image as a Windows Metafile
Format (WMF) or Enhanced Metafile Format (EMF) file, the resulting file is
saved as a Portable Network Graphics (PNG) file instead. This behavior
occurs because the GDI+ component of the .NET Framework does not have an
encoder that you can use to save files as .wmf or .emf files."

Thanks, Ken,
I really didn't see that before.
Is there any way to conver jpg to emf, and load it in C#?

Many thanks,

if emf is vector based picture, you won't be able to save an image to a
bitmap format, which is pixel based format.

File is jpg format, not emf. What I want to do is to convert jpg image to
emf file.
