Hi Francesco,

The first thing you need to know is in what format the graphic files are in the Blob field

(ie, BMP, JPG, ICO or BMP).

Then you can load the image in the appropriate Envision object, for example, a

TBitmapGraphic for a BMP graphic. Lookup TBlobStream in the Delphi help to see how to load a

stream from a blob field. The will allow you to use the BitmapGraphic.LoadFromStream method.

Then assign the graphic to a TiffGraphic:


After just call

TiffGraphic.AppendToStream(FileStream), where FileStream is a TFileStream created on the

multipage tiff file you are creating.

Note that you will need to create and free the objects as necessary.

Best regards,
