PDF Transparency issue

[RussellSenior]

I'm using a filled area with transperancy set at 50% to give a go/no-go box in Didem Report.  When copying to the clipboard, this works as expected. However, when exporting to PDF, the filled area is opaque, and I cannot see my data. I have attached two files from the same Diadem report.

Any suggestions how to fix it?

Hi RussellSenior,

For transparency support in PDF you need at least DIAdem 2011. In addition you need to set the REPORT parameters "Output to printer with transparency" and "Output print data as graphic". You can edit both settings in the REPORT parameters:

Ah, thank you very much!  

Just for my future reference:

ReportPrintTransparency=True
ReportPrintAsGraphic=True

I've been experimenting with this for a while, and the output as transperancy option doesn't seem to change the situation.  The output as graphic does fix it, BUT, the file size is now about 1MB per PDF page bigger.  So a 3 page PDF goes from 153KB to 3,649KB, which is quite a difference. Any ideas how to get PDF transperancy WITHOUT print as graphic?

With the variables

PDFOptimization
PDFResolution

you should be able to reduce the file size of the PDF.

Hi Russell,

In other words, you DO have to export as a graphic to get the transparency (in DIAdem 2012 and earlier), but you might be able to reduce the overall size of the resulting PDF file with those 2 properties. Here's an example of what we're talking about:

PDFResolution = "72 DPI"  '  "2400 DPI" ,  "default"
PDFOptimization = TRUE
PDFFontsEmbedded = FALSE
PDFJPGCompressed = "high"
