ADF Applications – Download DVT Charts in ADF 12c (and other technologies) by Pedro Curto


As we mentioned in past articles ADF 12.2.1 comes with several corrections of customer-reported and internal (unpublished) errors, along with new features that can be useful when developing applications. Recently we worked with ADF Visualization Components and we faced a big problem: there is no easy way to export a rendered DVT chart!
After doing some research in Oracle community and blogs we found that for ADF 11 there was one way: link

Unfortunately for ADF 12c the DVT class hierarchy was changed, and the previous method could not be used anymore. We did not find a way of using ADF classes to export the charts. The only suggestion was to use the <af:printablePageBehavior> to print the page. However, this will not fulfill the client’s needs so we had to try other ways.

With all these facts in consideration, we chose using JavaScript in order to export the charts generated by ADF. To clarify any misleading concepts, ADF charts are rendered as Scalable Vector Graphics (SVG).

This article will present a generic way to export and download the Scalable Vector Graphics as an image using JavaScript. In other words, the method presented can be used with ADF but also with other Application Development. Read the complete article lhere.
