C# Converting a 1bit BMP to version 3.0

Question

I currently have a C# project given to me that requires the converting any image to a 1bit Bitmap Image.

So far so good. The code is working perfectly well.

When the coverted file is sent to another colleague who needs it for a program that I can only guess was coded on the ark it throws this error:

resource file res\icon3.bmp is not in 3.00 format 

How can I get my application to save in a 3.00 format? It's a bit of a head scratcher.

Answer 1

School boy error! Although the conversion code was fine and working perfectly the error was with the image.save! Even though I had a bitmap file - while analysing the header it was a PNG. Very strange. The code was this:

 image.Save(newfilename);

After some headscratching this solved the problem:

 n.Save(newfilename,ImageFormat.Bmp);

I hope this helps someone.
