Saving jpeg image with C#

Question

I have a code:

Image image1 = Image.FromFile(sOriginalImageFileName, true);
....
image1.Save(sNewFileName, image1.RawFormat);

It works good for png's. But opening the new jpeg files with Photoshop, I get

"Could not complete your request because the file specifies an unsupported JPEG precision"

What am I doing wrong? Thanks in advance.

Answer 1

使用ImageFormat枚举

image1.Save(sNewFileName, ImageFormat.Jpeg);
