Hi Martin, I think we had a look at this issue at some point last year, as far as I remember, transparencies aren't very well supported with the pdf-image plugin. I think the best way to implement them would be to use transparency groups to that you can better control layered transparencies. However, I haven't looked at how easy/hard any of this would be to implement.
We investigated this a long time ago, so I could be wrong, but from your findings it looks like I'm not far off the mark. Sorry if that's not really of any help to you, Mehdi On 6 September 2012 10:46, Martin Edge <martin.e...@intellimail.com.au>wrote: > Hi,**** > > ** ** > > Wondering if I could get some advice on how to address the issue whereby > if a PNG is used within a PDF with a transparent background, and that image > is then put within a PDF, where then we rely on pdf-image to convert > (because ultimately I want to have the output use the less printer-resource > hungry postscript) – that the transparency is converted to a black colour. > **** > > ** ** > > Obviously the easiest answer is to just not use transparency, but I am > dealing with PDFs supplied from external clients, so it would be better if > I have a way of managing this.**** > > ** ** > > Ultimately what I am using this for is to generate flyer sheets for > printing, where I am taking a base PDF as initial artwork, and then adding > personalised address information for each recipient. **** > > ** ** > > Thanks in advance,**** > > Martin**** > > ** ** > > [image: Description: Description: intellimail_logo_small]**** > > *Martin Edge* > > > > **** > > ** ** > > ** ** >
