libharu : Link Annotation

[newtofoxpro]

Is it possible to create "Link Annotation" with libhpdf.dll in vfp ?

I trying

Annot=HPDF_Page_CreateLinkAnnot(IndexPage,Rect,Dst)

stuck at "Rect

 

[TamarGranor]

What is libhpdf.dll? Can you show us what the documentation says about this call?

Hi,
FoxyPreviewer and FoxCharts call LibHPDF.Dll
What is your exact goal here?

Like the others, I am baffled by what you are trying to achieve. Your "Link annotation demo" says nothing to me.

Above code in C I trying to make it in VFP

So you've given us around 250 lines of C, and you expect us to figure out for ourselves what it does and then to translate it to VFP for you, without knowing what your goals are or why you want to do this.

Sorry.

I am trying to make pdf file by VFP. For an example

Pdf file has 10 pages. 1st page has text like

one
two
three
four

when I click on text "two" it should jump on page 2.

stuck at "Rect

 

[Koen Piller]

OK, clear, but why do you want to construct this kind of complicted PDF file with VFP?
Have you tried FoxyPreviewer which has a nice PDF-construction protocol? Maybe that is a good starter for you.

I see his problem, in the sample c source he needs to pass a structure (object) with four properties

    rect.left = tp.x - 4;
    rect.bottom = tp.y - 4;
    rect.right = HPDF_Page_GetCurrentTextPos (index_page).x + 4;
    rect.top = tp.y + 10;

    HPDF_Page_MoveToNextLine (index_page);

    dst = HPDF_Page_CreateDestination (page[0]);

    annot = HPDF_Page_CreateLinkAnnot (index_page, rect, dst);

Could you use a variation on this:

oRect = CreateObject("Collection")
oRect.additem(123456,"left")
oRect.additem(123456,"bottom")
oRect.additem(123456,"right")
oRect.additem(123456,"top")

Perhaps?

Thank you Griff

how to declare

declare integer HPDF_Page_CreateLinkAnnot in (m.dll) integer, ??????, integer


Yes. I am trying Index-Page & Details-Pages

Best Regards

I thought you were past there...

In VFP for Windows API calls we do things like this:

	DECLARE INTEGER ShellExecute IN SHELL32.DLL ;
		INTEGER handle,;
		STRING @sFile,;
		STRING @lp,;
		STRING @DIR,;
		STRING @dir1,;
		INTEGER ncmd

I would imagine it's similar for your .dll

Sorry, I may have misunderstood, you are wondering how to declare the ??? parameter to which you pass the Rect structure?

I'd probably look at the .h file for clues - I have no idea at this point.
