Topic: Problem with PDEElementIsAtRect
Conf: (P-PDF) Developers, Msg: 82528
From: jlinfante

Hello.
I'm a newer in depelopment of plug-in.
I need to build a prototype to tell to my boss about pdf potenciality. I suppose, next, my boss pay the "developer license or similar" for me.
My english is bad, please excuseme.
My problem is:
I'm developed a tool. I select the tool. I click on a pdf with a lot of PDEElements (PDEPath stroke). Then, I receive the x, y coordinates of mouse click. Then, I execute a loop searching on all PDEElements, where is the PDEElement it is touched.
But, the response of "PDEElementIsAtRect" is false, all times.
I attach the code.
Can you help me, please?

The fragment of code is (based in SnapZoom sample):
----------------------------------------------------------
ACCB1 ASBool ACCB2 SnapZoomDoClick
(AVTool tool, AVPageView pageView, ASInt16 xHit,
ASInt16 yHit, ASInt16 flags, ASInt16 clickNo)
{
ASFixed currentZoom;
ASFixedRect apertureRect, apertureRect1;
AVGrafSelect pepe;
ASInt16 width, height;
ASFixedPoint p;
ASBool bEndedOperation = false;

AVDoc avDoc;
PDDoc pdDoc;
int pageNum;
PDPage pdPage;
PDEContent pdeContent;
PDEElement pdeElement;
int j;
AVRect rect;
char Texto[128];

DURING
AVPageViewBeginOperation (pageView);
AVPageViewDevicePointToPage(pageView, xHit, yHit, &p);

apertureRect.right=p.h + 100000;
apertureRect.left=p.h - 100000;
apertureRect.bottom=p.v + 100000;
apertureRect.top=p.v - 100000;

avDoc=AVAppGetActiveDoc();
pageView=AVDocGetPageView(avDoc);
pdDoc=AVDocGetPDDoc(avDoc);
pageNum=AVPageViewGetPageNum(pageView);
pdPage=PDDocAcquirePage(pdDoc, pageNum);
pdeContent=PDPageAcquirePDEContent(pdPage, gExtensionID);

sprintf(Texto, "right=%d left=%d bottom=%d top=%d", apertureRect.right,
apertureRect.left, apertureRect.bottom, apertureRect.top);
AVAlertNote(Texto);
sprintf(Texto, "NumElems=%d", PDEContentGetNumElems(pdeContent));
AVAlertNote(Texto);
for(j=0; j {
pdeElement=PDEContentGetElem(pdeContent, j);
if(PDEElementIsAtRect(pdeElement, apertureRect)==TRUE)
{
AVAlertNote ("You click on a object!!!");
AVPageViewRectToDevice(pageView, &apertureRect, &rect);
AVPageViewDrawRectOutline(pageView, &rect, 1, NULL, 0);
break;
}
}
