Image vs Bitmap class

Question

Afternoon all,

As this is my first post, let me introduce myself, I am Kadrin. I'm a developer at a large corporation in the central United States and have been out of college for about 1 year.

Anyway, I've been reading up on my C# alot lately (my team is slowly moving over to C#) and am having troulbe understanding the differences between the Image class and the Bitmap class. Now I know Bitmap inherits the Image class but from what I understand both are very similar. Can anyone shed some light on this please?

Answer 1

The Bitmap class is the generalization of the Image class. The Image class is an abstract class;

The Bitmap class contains 12 constructors that construct the Bitmap object from different parameters. It can construct the Bitmap from another bitmap, and the string address of the image.

Answer 2

Image provides an abstract access to an arbitrary image , it defines a set of methods that can loggically be applied upon any implementation of Image. Its not bounded to any particular image format or implementation . Bitmap is a specific implementation to the image abstract class which encapsulate windows GDI bitmap object. Bitmap is just a specific implementation to the Image abstract class which relay on the GDI bitmap Object.

You could for example , Create your own implementation to the Image abstract , by inheriting from the Image class and implementing the abstract methods.

Anyway , this is just a simple basic use of OOP , it shouldn't be hard to catch.
