SQL Server Developer >> Extracting BLOBs and drawing on vb.net form?

Hi

I am newbie to graphics and want to perform the following task

I have signatures drawn on the form using xy coordinates(similar to drawing in a paint brush) and stored in 'image' datatype of sql server 2000 table. I want to extract them from database table and draw on a vb.net form as X & Y points/coords and make an image of signature again. Also, Can anyone tell me how is the data stored in image datatype? I mean, binary data, hexadecimal data etc. If so, how to convert them into integers of xy coords/points? Can anyone help me in this

Your help/ suggestions is greatly appreciated

Thanks
P

SQL Server Developer >> Extracting BLOBs and drawing on vb.net form? You want to use the article below to help you extract the blob into an image
obj. You then place the image on the form based on whatever coord.
