Hello !
I need to DrawTextBox on top of a background image. So, I needed the box to be transparent.
How can I do that ?
Here's a test script :
OPTION EXPLICIT
DIM objQPDF,lni,lnt
DIM X1,Y1,W1,H1,A1,S1,TW
Set objQPDF = WScript.CreateObject("ISED.QUICKPDF")
objQPDF.unlockkey("yourkey")
objQPDF.NewDocument()
objQPDF.DocumentCount()
objQPDF.LoadFromFile("TEST037.PDF")
' YOU MAY GET TEST037.PDF from http://www.DES.online.unimep.br/au/pub/TEST037.pdf
lni=1
X1=objQPDF.GetFormFieldBound(lni,0)
Y1=objQPDF.GetFormFieldBound(lni,1)
W1=objQPDF.GetFormFieldBound(lni,2)
H1=objQPDF.GetFormFieldBound(lni,3)
A1=objQPDF.GetFormFieldAlignment(lni)
S1=objQPDF.GetFormFieldTextSize(lni)
lnt=objQPDF.FORMFIELDCOUNT()
for lni=lnt to 1 step -1
wscript.Echo objQPDF.GetFormFieldTitle(lni)
objQPDF.DeleteFormField(lni)
next
objQPDF.SetTextAlign(0)
objQPDF.SetTextSize(S1)
TW=objQPDF.GetTextWidth("JOSE ADRIANO BALTIERI")
CALL objQPDF.DRAWTEXTBOX(X1,Y1,W1,H1,"JOSE ADRIANO BALTIERI",0)
WScript.Echo objQPDF.SaveToFile("TEST037OUT.PDF")
WScript.Echo "OK !"
When I draw "JOSE ADRIANO BALTIERI", I needed it to be in transparent mode.
Any help ?

I've done this in the past, don't remember exactly how, maybe SetTransparency() function?

Yeah, I had seen that before but it doesnt work.
It sets the transparency of the TEXT itself but I need something to set the transparency of the BOX underneath....

I think your problem is with the form fields themselves. They aren't transparent, and are overwriting the image underneath. QuickPDF deletes them, but not the white background.
What you can do is use the PDF with the form fields to get your locations, but use the original PDF without the form fields to write your text on.

Yep, just validated this. Loaded the PDF in NitroPDF, removed the form fields, and saved. The white blocks are still there.
Whatever you're using to add the form fields is the actual problem.

Sorry, I dont get it.
You mean that the problem is on the PDF template itself or on my script ?
Should I use something else to draw my template then I'd be ok, is it ?
Thanks !

The problem is with the PDF template. The form fields are wiping out the image underneath. Deleting the form fields leaves the white blocks.
If you use the original PDF before you added the form fields, the problem will go away. Just get your field locations from the one with the form fields.
