C++ code to create text link to named destination?

[hcobb]

I'm currently using rectangle links that clip into the text that I want the user to click.

Does anybody have c++ code for Acrobat Pro DC to

1. Create a named destination to a page number that is currently valid, but allow the user to come in later insert pages in between and retain the destination.
2. On a different page add what appears to be (and prints as) ordinary text but is actually a link to the named destination.

Failing that, how do I turn my rectangular link annotations invisible so they don't interfere with the link text?

[Bernd Alheit]

1. you can create a plugin which adds the named destinations

[hcobb]

Yes, I am writing a plugin. Do you have any sample code that does this?

[Bernd Alheit]

Sorry, I don't have.

Links /are/ ordinary text. Links are an overlay on the page.

[hcobb]

Do you have any sample C++ to create invisible links?

[Test Screen Name]

Please don’t ask for samples. Are you having trouble finding the info you want in the documentation?

[hcobb]

Yes, the documentation for link options is very sketchy.  It shows how to make a colored rectangle only.

Which API do you use at the moment? I ask because there are multiple overlapping APIs. Are you trying to use only the plugin guide or are you using the API Reference too?

Here is the C++ code I am using currently to put a white rectangle around the link. Can I make it transparent instead?

  // Box around the link

  ASFixedRect initialRect;

  initialRect.left = ASInt32ToFixed(writeLeft);

  initialRect.top = ASInt32ToFixed(writeTop -5);

  initialRect.right = ASInt32ToFixed(endText +2);

  initialRect.bottom = ASInt32ToFixed(writeTop - lrint(1.5 * fontSize));

  PDPage gotoPage = PDDocAcquirePage(pdDoc, linkedPage);

  ASFixedRect destRect;

  PDPageGetCropBox(gotoPage,&destRect);

  PDViewDestination aViewDest=PDViewDestCreate(pdDoc,gotoPage,ASAtomFromString("XYZ"),&destRect,PDViewDestNULL,0);

  PDPageRelease(gotoPage);

  PDAction aAction= PDActionNewFromDest(pdDoc,aViewDest,pdDoc);

  PDAnnot aLinkAnnot = PDPageAddNewAnnot(pdPage, -2, ASAtomFromString("Link"), &initialRect);

PDLinkAnnotSetAction(aLinkAnnot, aAction);

PDColorValueRec colourWhite;

memset (& colourWhite, 0x00, sizeof (colourWhite));

colourWhite.space = PDDeviceRGB;

colourWhite.value [0] = fixedOne;

colourWhite.value [1] = fixedOne;

colourWhite.value [2] = fixedOne;

PDAnnotSetColor(aLinkAnnot, & colourWhite);

PDAnnotSetTitle(aLinkAnnot, linkText.c_str(), linkText.length());

PDEContentAddElem(pageContent, kPDEAfterLast, reinterpret_cast<PDEElement>(textObj));   

PDPageSetPDEContentCanRaise(pdPage, NULL);   //Set the content back into the page.

PDERelease(reinterpret_cast<PDEObject>(textObj)); // Done

This turned out to need a lot more research than I was expecting, though this is fairly typical. I created two link annotations in the UI. One with a visible border and one without. The only difference was the visible one had /Border [0 0 1] while the invisible one had /Border [0 0 0]. This could be done with the Cos layer, but I believe the simplest API is likely to be PDLinkAnnotSetBorder .

[hcobb]

Yes, that works. My revised code is then: (Note no color setting as the border has no width to color)

// Box around the link

  ASFixedRect initialRect;

  initialRect.left = ASInt32ToFixed(writeLeft);

  initialRect.top = ASInt32ToFixed(writeTop -5);

  initialRect.right = ASInt32ToFixed(endText +2);

  initialRect.bottom = ASInt32ToFixed(writeTop - lrint(1.5 * fontSize));

  PDPage gotoPage = PDDocAcquirePage(pdDoc, linkedPage);

  ASFixedRect destRect;

  PDPageGetCropBox(gotoPage,&destRect);

  PDViewDestination aViewDest=PDViewDestCreate(pdDoc,gotoPage,ASAtomFromString("XYZ"),&destRect,PDViewDestNULL,0);

  PDPageRelease(gotoPage);

  PDAction aAction= PDActionNewFromDest(pdDoc,aViewDest,pdDoc);

  PDAnnot aLinkAnnot = PDPageAddNewAnnot(pdPage, -2, ASAtomFromString("Link"), &initialRect);

PDLinkAnnotSetAction(aLinkAnnot, aAction);

_t_PDLinkAnnotBorder border;

PDLinkAnnotGetBorder(aLinkAnnot, &border);

border.width = 0;

PDLinkAnnotSetBorder(aLinkAnnot, &border);

PDAnnotSetTitle(aLinkAnnot, linkText.c_str(), linkText.length());

PDEContentAddElem(pageContent, kPDEAfterLast, reinterpret_cast<PDEElement>(textObj));   

PDPageSetPDEContentCanRaise(pdPage, NULL);   //Set the content back into the page.

PDERelease(reinterpret_cast<PDEObject>(textObj)); // Done

can you please send me the code for rectangular selection, i'm facing problem.

[Test Screen Name]

Why would you expect us to write your code for you?

[Chenchaiah5C1E]

Atleast explain the flow, How to select rectangular area/how to select text through arrow cursor.

I tried, Its not working.
