Thank you, Trevor, 
Kirill, try this syntax.

Trevor, our above syntax is not correct?
It seems the same logic and Revolution do not complain.

We do not store format of picture. We just store JPG or TIFF itself and all
other ADKs. Because it is possible recognize type of picture by its data.


Trevor, also we do not see in Revolution Examples any example that show work
of picture via RevDB. Does exists such example?

In fact I have many questions about this :-)

E.g. Do you use *b in real life?
you send pictures into RevDB using *b ?
Just I am not sure how then to recognize format of picture...

Well, for now we need make working Valentina Native API.


--------
We plan next syntax:
    
    set the imageData of imgage "pic2" to dataPic
    Picture_Set( fldRef, "dataPic" )


In v 1.x was similar code but picture have go just into BLOB field:

    set the imageData of imgage "pic2" to dataPic
    Binary_WriteData( fldRef, "dataPic" )

It is not good write into BLOB, because such pictures will not work in other
Valentina ADKs. Must be Picture column type...


--------------------
About BLOBs.

Does for Revolution developers have any sense and if they have such ability
in revolution itself prepare some binary data and store them into BLOB
column?

    set SOMETHING BINARY to data
    BLOB_WriteData( fldRef, "data" )
