Code sample

// Open the PDF file.

long hVPDF = BiPDF.vpdf_OpenVectorPDFFile(szFileName, szPassword, 0);

int nPages = BiPDF.vpdf_GetNumberOfPages(hVPDF);

// Iterate through all pages.

for (int iPage = 0; iPage < nPages; iPage++)

{

// Retrieve the page size in Points (1/72 inches)

double dWidth = 0.0, dHeight = 0.0;

BiPDF.vpdf_GetPageSize(hVPDF, iPage, ref dWidth, ref dHeight);

// Start the search on the page.

BiPDF.vpdf_BeginSearch(hVPDF, szSearchPhrase, iPage);

// Iterate through all search results.

while (BiPDF.vpdf_GetNextSearchResult(hVPDF))

{

// One search result may consist of multiple rectangles,

// iterate through the rectangles.

int nRect = BiPDF.vpdf_GetSearchResultRectangleCount(hVPDF);

for (int iRect = 0; iRect < nRect; iRect++)

{

double dLeft=0.0, dTop=0.0, dRight=0.0, dBottom=0.0;

if (BiPDF.vpdf_GetSearchResultRectangle(hVPDF, iRect,

ref dLeft, ref dTop, ref dRight, ref dBottom))

{

// Process the results.

// Coordinates are in Points (1/72 inches),

// relative to the bottom left corner of the page.

...

}

}

}

// Finish the search

BiPDF.vpdf_EndSearch(hVPDF);

}

// Close the file.

BiPDF.vpdf_CloseVectorPDF(hVPDF);
