Default Image Processing

Hi Rod

I have been reading the chapter on Image Processing to see if it can help with something I would like to do. Looks like the bitmap class is what I need to work with but.....

Here is what I want to do.

Create a class which contains the image file name, an key value, and the image itself as a bitmap (could be a jpg, gof or bmp)

Create an arraylist or similar to collect a bunch of these

Serialize them to disk

De-sericalize them back to the original class and use the information about the file name to add to a hashtable based on the key, plus store the image as a file on disk.

I guess this depends on the bitmap class being serializable but I cannot see that it is

thanks in advance

OK figured it out - bitmaps are serializable so creating a serializable class which contains the classification data and the bitmap works just fine. My test code imports a directory of images into a hashtable. serializes it to disk, deserializes the file and copies the images to a new folder. I notice that bitmap.save will just overwrite without warning if the file already exists so I need to add code for that
