Can't get SaveImage to work

Hi.
I have a TIWCGJQMSignature and a TIWCGJQMImage on a form.
In the forms OnCreate i load the signature from a field in my database and export it to the image.
I can see the image on screen but i can't save it to file. I step in to the source code and when it executes to
"if (AFileName <> '') and Assigned(FPicture) and (not FPicture.Empty) then
SaveImageToFile(AFileName,FPicture.Picture);"
It skips saving to file because FPicture.Empty=True.
Any suggestions?
Sören A.

When you export TIWCGJQMSignature to image, the image is setted by data on user browser, and doesn't fill the Picture property.
We will try to find the solution for this asap.
Best Regards.

Hi and thanks for remote help with my installation problem.
I just wanted to check on this issue. Is it resolved yet? I still can't get it to work in version 1.7.0.2989

Hi Soren,
Please check "SaveAsImage" procedure in JQMSignature at current release.
delphi code
IWCGJQMSignature.SaveAsImage('C:\yoo.png');Best Regards.

Yes, saving directly from the signature component is even better. However, i run the procedure but can't find any image file after. Do i need some special properties or permissions set?

It should work, maybe you don't have permissions on folder.
Best Regards.

Nope.
I'm saving it to WebApplication.UserCacheDir and the application can save other files there...
Could you send me a simple demo of this? For mobile that is.
