Re: PDF Export: adding the print options

Brian,

Good to make PDF export better, more professional. We uses the export a 
lot to deliver PDF to our professional print houses.
It works very wel, exept the lack off  "boxes" in the PDF file
TRIMbox = where to cut the printed result (needed for pinting)
BLEEDbox = is mostly TRIMbox + 5mm  (needed for printing)
MEDIAbox not realy needed
CROPbox not realt needed

we to the printing with the API and basic code

below our code with all the Filterdata we know off (maybe there are more ?)
so we need some  filter options to set the TRIMbox and the BLEEDbox

pdfHighResFilterData() = 
array((makepropertyvalue("UseLosslessCompression", false))
 AddPropertyValue(pdfHighResFilterData,"Quality",90) ' enkel als we 
UseLossLess FALSE is (dan is het jpg)
'AddPropertyValue(pdfHighResFilterData,"ReduceImageResolution",true)
'AddPropertyValue(pdfHighResFilterData,"MaxImageResolution",150) ' only 
if  reduceImages = TRUE and only  75, 150, 300, 600, 1200 available

oDoc.storeTOURL(path,oExport)

hope i helps
