To pull the image out of blob filed

[Jayasri9]

I have an imd4 db file which consists of a lot of images in it. It is a read-only database. So, can anyone help me out to decompress these blob fields and pull the image out of it?

Did you put the images into your "blob" fields yourself? How?
Or do you want to extract thumbnails from an IMDB4 file? This could be done by converting the database to IMatch 5, open it and then use a script. Use the GetThumbnail method of the database class and the Image class to save it.

The plan is to either extract the image or at least the thumbnail of that image. I tried the conversion from imd4 to that which fits imatch5 but the conversion fails every time. It is probably because the database we have is really huge(imd4 file size is around 4 GB). Also give details on how using scripting can we convert the blob filed as an image. And if we get another copy of this database with write access will we be able to extract the images out?

A 4 GB database is not very large.

Please send me the up to 3 log files produced by the database converter. The names of these log files and where to find them are explained in the database converter help file (click on the HELP button in the dialog).

First thing to make sure is that the database completes the database diagnosis in IMatch 3 without error.

The log files may allow me to tell you what the problem is and how to successfully convert your legacy database.
