Hi,

Make sure all of your pictures have the same width x height ratios.

Set your datawindow to pixels instead of PB Units.

Adjust the size in pixels of the column to be exactly the same as the picture's. (or at least the same proportions).

Hi King;

  Is your DataWindow using the following approach ...

• A Column where the "Display as Picture" property is set.
• A real Image object control within the DWO
• Table BLOB type DWO

if you use a picture control on the datawindow, you can have it use the 'original size'.  That is the closest thing you have directly in the datawindow to sort of tell you what the aspect ratio is.

Using that, or some other process, you would need to calculate the size (width/height) and use that to determine the aspect ratio.  At runtime you would have to change the width/height of the column/compute based on that ratio to get it to display correctly.

you should send appeon an enhancement request to have the datawindow to do that automatically (keep the aspect ratio)

Thank you for your reply. I use "Display as Picture" in datawindow so that there is no "Original size" option for the object. If I use picture object in datawindow, how can I dynamic change the picture filename in each row? Thank you!
