Re: Page Overlay (IPO) Extension
Hi Jeremias, Thanks for your help. I have done few changes to the AFPPageSetupElement.java, and the offset coordinates are working infact. I just want to know more on your other point mentioned in your reply 'offset coordinates user-friendly'... There is some code I have found in *org.apache.fop.afp.AFPUnitConverter* , namely the method *public int[] mpts2units(float[] srcPts)* Is this the same method you are suggesting me to use to map the user-friendly offset coordinates to get converted into float values? Thanks, Venkat. Jeremias Maerki wrote: Venkat, first of all you probably need to subclass AFPPageSetupElement to add support for carrying the offset coordinates. AFPElementMapping would then also need to be changed. Then you'd need to move on to AFPDocumentHandler.handleExtensionObject where the extension is converted into calls into the AFP library. DataStream.createIncludePageOverlay would then also need to be extended. And so on and on... I guess one challenge is to make the specification of the offset user-friendly. I don't think it's acceptable to expect from the user to know what numeric value would need to be specified to get the right placing. Maybe you can reuse something from the FO property subsystem to parse arbitrary lengths, internally work with millipoints and then convert that to the final value.
