Image transparency in Appeon Web and Mobile

Hi All,

How are people handling the use of transparent PNGs in their Appeon Web and Mobile development?

We are creating some proof of concept apps to come up with some standards, i.e. common header and navigation icons, etc.

We are having a problem using Transparent PNGs on our objects.  I did find some old posts about Image transparency not being supported by Appeon, but these were from 2013.  Has this changed?

When we run our sample app via Powerbuilder on the desktop all the images appear correctly, see below.

When we run in the Appeon Workspace Emulator, our images seem to display everything below them.  Overlapping images are being displayed, even though their visibility is FALSE.  You can also see the Emulator background coming through.

When we run in the browser all the image backgrounds are Black!

Any advice on this would be appreciated.  Are Transparent Images supported yet?  or should we use a different option?

Have attached the Transparent PNGs that we are using.

Its also a mixed bag of support BTW. For example:

1) Animated GIF's work in PB, Appeon Web but not in Appeon Mobile.

2) The transparency property has no effect in the DW but transparent images work.

FWIW: Sometimes, I end up layering the effect within the image itself using GIMP in order to have the layered transparent image display properly in all three environments.
