Dynamic BLOB Decompression?

stormdude

Hello,

We are accessing the Navision SQL server and retrieving the BMP data from an image field for use in a custom VB.NET application. It appears COMPRESSION is enabled, so our application cannot properly display the image.

We realize that turning off compression for the BLOB field will correct the problem, but we would like to avoid that if possible. Is there a method we can use to decompress the image data "on the fly"? Or is turning off compression the only solution people have been able to successfully implement?

Any assistance or direction is greatly appreciated!

Unfortunately there is no documentation on the compression method NAV Exe is using.

Sorry, we doesn't know how NAV compress the data in a BLOB. The only way we are know (see all the posts in this forum to this theme) is to disable the Compressed Property on the BLOB field.

I think I read that it is Base64 encoded (same like emails).
