I created a picture control that supports rotate/flip:

It isn't a DataWindow picture control, a regular window control.

That's awesome Roland! You could still use a DWO though but process the image through your picture control (just hidden) to do the "work" and then transfer the image back to the DWO for zooming. ;-)

PowerBuilder does not have this capability, but there are many utilities available that will rotate a graphics image stored in a variety of formats. The Paint utility in Windows 10 does this.

In PB Help, search on "datawindow object properties" on the Index tab, press Enter, Miguel. A selection dialog pops up. Choose the item listed as "DataWindow Object Properties". On that Help topic there are three different ways the information is presented.

Escapement is a sub-property of the Font property for a DW object that displays text.

Thank you John! It's always been "an art" to find the correct information in the ever changing help files. (sometimes I go back to using the help file of 12.0, because I know the search string that will give me the correct information. In later version that might have changed).

regards.

Nevertheless ... can't seem to find the "escapement" attribute being documented for picture nor inkpicure objects. This is what I mean when I say "no one seems to bother to complete the documentation on all attributes". I think I have an open ticket somewhere asking to update the Tool for dwsyntax.

Thanks anyway!

regards.

I would really recommend ImageMagicK for that. I have built entire imaging systems using that open source software to basically do any image manipulation / conversion that I needed (on the fly) by calling IM from both PB Apps, Appeon Web Apps and IIS Web Services. Then I used the DWO for image display purposes to support Zooming. Here is a presentation that I did on some of those PB Imaging Apps for a PB conference ...

" If you display any column as a picture, you can use the "Escapement" property to rotate the DWO's data elements "

this doesn't work for me, at least not in the IDE using dw preview using a jpg.  (PB2019R3 2703)

  1. use column name and display as picture option, it has font so escapement is an option but it does not rotate (text does, not pictures)
  2. use compute with bitmap function, it has font so escapement is an option but it does not rotate
  3. use picture control.  Picture currently has the most options (invert and original size) but not escapement.

 

Also miguel- chris said he was displaying column as a picture, not using picture/ink with escapement.  so documentation seems correct for those.
