 The reason to display this dialog is: somehow "just save" is

 Also, is it possible to have a "Save" or "Download" button on the
 preview box, rather than telling the user to right-click?

Re: [DISCUSSION] download whiteboard as png

[Daniel Ascher]

Works well! Thanks. I think this is a good solution. However in English, it
should read:

Please right click the image and choose "Save image as"

Thanks! Dan

 Hello All,

 Here are some details

 by default Tomcat has limitation of 2Mb for post data [1] (maxPostSize)
 You can change this in OM 4.0.x by changing conf/jee-container.xml
 You need to add
  
   
>>> value="4000"/>
   
  
 to ''

 This should fix Huge PDF download


 According to PNG download: it can be done "by click" BUT
 It will only 100% work if it will be dobe "via server" i.e.
 1) image will be prepared in client's browser
 2) uploaded to server
 3) then immediately downloaded
 This "server round trip" might be very expensive

 You can see how proposed pop-up dialog will look like [2]
 I can update demo-next with working prototype so you can try it :)

 Prepared image will have constant size something like 320x240, sort
 of preview :)
