Database Imaging

LEADTOOLS has specific features designed for the imaging database developer. VB data binding allows you to use the Visual Basic JET engine to store and retrieve image to/from any database supported by JET. LEADTOOLS has support for 32-bit ODBC, which allows you to work with any ODBC database. LEADTOOLS provides a customized OLE 2.0 in-place server which can store and retrieve images into/from any OLE client. Load/Save memory and Load/Save file offset functions provide low-level methods for working with databases.

You can use the database features to store images in any of the file formats supported by LEADTOOLS. LEADTOOLS' database support includes a wide variety of callback routines and features multipage support.  These features, when combined with the excellent compression options available in LEADTOOLS, provide a solid base for building robust database applications such as those used in fields like Real Estate, Law Enforcement and Internet on-line shopping.

You can maintain images in a database, using any valid file format to store an image in a long binary field. You can do so as follows:

• [ActiveX32 and VCL only] Use Open Database Connectivity (ODBC).

• [ActiveX32 only] Use OLE DB.

• [ActiveX with Visual Basic and VCL only] Use data binding.

• Use functions to read files from memory and write files to memory.

• [DLL and ActiveX] Use LEAD OLE server to embed or link images in any database that supports an OLE field.
