Good morning!
I would like to know how to zoom in on an image in the userobject component, or
Set an image from the blob database in a datawindow.

Grateful.

Hi Marco;

  FWIW: in the past, I've built Apps with images inside a DataWindow as the DWO's are completely zoomable. HTH

Regards ... Chris

Excellent,
How do I set it when it comes from the bank?
Example:
SELECTBLOB img_assinatura
INTO :lb_assin
dw_3.Object.datawindow.AddPicture(lb_assin)
dw_3.Object.datawindow.SetPicture(lb_assin)

But it's not working.

Grateful.

Correct ... that won't work.

After the SelectBlob, you need to write the image contents to a file. Then assign the external path/file of the image file to the picture control / column that you wish to have it displayed.

The other alternative is to use a TableBlob based DWO approach.

You can also display an image in a web browser control which would make it much easier to resize or even open an external browser.  Be careful if there's any confidential info displayed, you will need to clean up the data files after you use them.
