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

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.

It seems that the widget always defaults back to WGS 84 Web Mercator Auxiliary Sphere and will not read any of the other proj files specified. I also dont see an aux xml file. Is this a known issue? Any chance to have an option to export the file to specific coordinate system within the widget?
