Question

I know, I know… there are many others posts like this. I didn’t find what I was look for, let’s move on.

I break a PDF into images using this GhostScript implementation for C# and then try to load each image into a Bitmap, sometimes it gives me a Parameter is not valid error on this line:

[...]new Bitmap((Image)Image.FromFile(imagePath))[...]

Image.FromFile(imagePath) successfully returns an Image (though I think it’s returning a Bitmap) but then Bitmap’s constructor gives me the error. What am I doing wrong?

P.S.
I’m casting the result to Image because when I quick watch the result of Image.FromFile(…) it shows it as a System.Drawing.Bitmap (either way, cast, no cast, yields the same result).

Answer 1

Try using the Bitmap constructor that receives a path to the image like so:

var b = new Bitmap(imagePath);
