Description

The ExtractJPEG program was born from a need to extract JPEG images from an old database file, for which the database software was no longer available. Without any knowledge of the way in which the images are stored, the program was designed simply to look for properly formatted JPEG file headers, and then extract any subsequent data as part of the JPEG image. This works well, provided that the images are stored in JPEG format and each image is stored as a complete record. In fact, in some database formats, there is a fixed size database record, or a maximum size limit on database records. In this case, large images might be broken up into many separate records, each containing part of the JPEG file. The ExtractJPEG program can still deal with this case, provided that all of the records associated with the image are stored consecutively in the database file. There may be other data, such as database record header information, between each segment of an image. ExtractJPEG can handle this case and put the image segments back together, removing the gap data between segments, provided that the user can enter a "segment size" and "gap size". For an unknown database, this may require some trial and error attempts at extracting images to get it right. It is possible, however, that the individual records making up a stored image are not located consecutively within the database file. In this situation, the application might only be able to extract part of the image data or corrupted bits.The program will attempt to extract valid image data only, it cannot find the original file name of the stored JPEG images. The image files output by this process will all have the ".jpg" extension and will have the output file name selected by the user, but each will have a unique image number appended to the file name. Requirements:

· 1MB free hard disk space, plus extra space for storing extracted image files.
· An image viewer program to view any images that are extracted.
