For example, you could use our Raster IO COM object to do that. Qasem Al-Lubani LEAD Technical Support www.leadtools.com    Report

My image is stored in database as image type. How to load this information into raster io? sould  I use loadbuffer or loadmemory function of raster io? could  you send me an example or few lines of code?      Report

You should also be able to use LoadBuffer and LoadMemory as well, but it depends on how the file is stored in memory.  For an explanation on which to use when, read the documentation on LoadBuffer.
