I have a nested main datawindow with several nested dw's inside. One of the nested dw's is a graph that is created via a blob object in its detail band.
I create a pdf (native!) using saveas. When I open the pdf the graphs shows for a second and then disappears. Using Acrobat pro (edit tool active), you can click in the space where the graph should be and get a box outline which you can drag down and the graph is there. In the main dw, I have selected the nested graph dw and right clicked and select Bring to Front. I did the same thing with the blob object on the nested dataobject but neither setting fixed the issue. I have listed powerbuilder version info at the bottom of this post. I don't think this a coding issue because I can retrieve the graph dw in the dw painter and do saverows as pdf and the behavior is the same - when you open the graphs shows but then disappears. I have attached this pdf.  Another FYI - this same datawindow worked fine in PB10.

 

Here are the blob properties:

Using PB21 and I have installed ghostscript 10.01.2 and setup the Sybase Datawindow PS printer. In my application object on PDF export tab, I have checked 'always use Native! PFD method for PDF export'. In the IDE I  open a datawindow in the painter and I have the following properties set:
I retrieve the dw and do Save Rows As PDF. In this scenario the pdf is successfully created - how can I verify that is using ghostscript (not Native!)?

Hi Paul,

I believe if you set the Application Object properties to use NativePDF! then it will use this setting regardless. That being said, if you have Adobe (reader) installed, you should be able to open the document, select properties and look at the PDF Producer field on the Description tab and confirm how it was generated. You can also use MS Edge or Chrome and look in the Document Properties section and it will show it as well.

Regards...Mark

You are correct Mark ... Them the NativePDF feature is then *always used* no matter what any DW object;s PDF Export Settings are).

After installing ghostscript, can someone please provide detailed instructions as to what else needs to be done in order to do a datawindows saveas to pdf using the Distill! method.

I have the application setting to always use Native on the PDF export tab. If I change an individual dataobject to use Distill! - does that override
the application setting for that dataobject? When you do a datawindow saveas, is there a way to know if it is using native or ghostscript?

Hi.

Set <your dw control>.Object.DataWindow.Export.PDF.Method = distill! just before performing saveas.

This is the way to choose the method to use to save as pdf.

Hi,

In PB 10.x you would have used GhostSript and not NativePDF. Try if that (GhostScript) still works. If it does, the please create a bug ticket for the NativePDF failing.

regards.
