Hi,
here is a new version for the FlexViewer 2.2

The selection rectangle is now movable and resizable.

Erwan,

My image has a dark background.  Have you ever seen this behavior?  I haven't added any background color to my config.xml file.  Attached is a screen shot.

Thanks

Eric,
i think your layer is transparent and your flexViewer as a white background, is'n it ?

When you save the image, (try as JPG and as PNG please) does the image saved have a black background too ?

Thanks

Erwan

Erwan,

Yes, the saved image in jpeg shows as black.  The png format looks fine.
My FlexViewer has a white background.  The map services I use as Basemap layers are tiled - PNG8 & JPEG

Thanks
Eric

Eric,
coul'd you please post the REST end points of the basemap services used ?

Erwan.

Erwan,
I have 5 basemaps, none of which are publicly accessible.  I have all the basemaps tiled.  4 of the 5 are aerials and 1 is a "google-like" streets basemap.  How should I post the endpoints?  I have attached a PDF of one of them.

Thanks
Eric

Erwan,
Can you give me some guidance on why the background of the jpg image is black?
Thanks
Eric

Hi, thank you very much for this useful widget. I wondered if tehre was a way to include the Overview map into the image if this is displayed in the map?

Thanks again,

Caroline

@caroline1981 : Thanks for the suggestion, i'll include it in the TODO list.

@ericv : I reproduced your problem, whith a tiled service cached in a mixed format. I try to find a solution.

Edit : The JPEG Encoder in Action Script 3 does not support transparency .... you'll have to export in PNG if you need it.
