Author Topic: Image stream (Read 3929 times)

The Image constructor accepts Stream as one of the overloads.
I have an embedded image (a png file) and I'm loading it into a stream with Assembly.GetManifestResourceStream("name");

Then I make an image from that stream but it throws an error.
Object reference not set to an instance of an object.

If I use a .bmp image then it works fine.
Is there any way to load a png image?

Where does this happen? For which variable? Are you sure that the returned stream for your png image is a valid one (ie. no error happened)?

The error is on this line

Image img = new Image(stream);

The problem might be that Stream stream = a.GetManifestResourceStream("name.png");
doesn't know how to convert a png to a stream.
Keep in mind I don't know what I'm talking about, just guessing.

Same for me, never used streams in C# :lol:

But I think that this error means that you have an uninitialized object.
