Today I developed a little program to verify finger prints gathering from the FR 500 finger print reader. I used several APIs to develop the program.

These APIs all are difficulty. There are several types defined and macros. I have to get their usages from several sample project, and make them in a whole.

There is steps to get and verify a finger feature.

1. initial a device context, verifing context and so on;

2. get a bitmap from a finger reader;

3. extract a finger feature from the bitmap;

4. verify a finger feature.

5. free the device context, verifing context and so on.

In these steps, I have to use several APIs. We can wraps them into a package.
