[V4RB] VPicture challenges

[Pedro fp]

G'day Folks

Project I'm working on is an ID photo database using Valentina & I'm 
having trouble with the picture field.
In a variety of ways, including drawing it to a canvas, I've tried 
testing that the picture object returned from theFile.openAsPicture is 
not nil, always yielding a positive result. However the picture never 
seems to go into my database.

I have a class importItem which has properties for the picture (a RB 
picture object) & the person's name. As I loop through a folder 
selected I create an array of importItem objects from any JPEG files 
found in that folder. That array is then passed to a method of the 
Valentina base object that creates the new records.

Setting a breakpoint immediately before passing the array shows that 
the picture property for all items is not nil. However the blob file of 
my database remains the same size (100 KB) both before and after the 
import. Then when I try to retrieve the pictures nil is always 
returned.

The constructor for my picture field is ...
     fPhoto = new VPicture( "photo", 20 * 1024 )

(I have also used 1024, the default value, as the 2nd parameter)

The picture is set to the new record using ...
     me.fPhoto.setPicture( batch( i ).photo, 80 )

(batch is the array of importItem objects)

The data is retrieved using ...
     dRow( i ).icon = data.PictureField( "photo" ).getPicture

Any clues to what I'm doing wrong? Or where I should look for the 
problem?
Also, can anyone offer a guide to selecting an appropriate value for 
the segment size in the constructor of my VPicture field?

Cheers, Pedro :-)
