[Gambas-user] Size of a picture

[rolf]

Hi everybody,

I would like to store a picture in a postgresql database. So every non char 
(i.e. A-Z, a-z, 0-9...) have to be quoted as octal numbers with two leading 
backslashes. Because the Replace function only works with strings I have to 
loop through the picture data and do the substitution by myself.

To do so, I need the number of bytes the picture has. How can I get this 
value?

Many thanks in advance
Rolf
