how can I find a particular image in a PDF?

Hi all,   I have 10 PDFs, my requirement is that I have to search a specified image in these PDFs, and validate if it is present or not and if present, get the page number where the image was found...

Hi,

 

Thanks for the help. I am getting the an error : Object doesn't support this property or method

 

 

function test()

{

 

strPDFPath = "J:\\Documents\\PV.ps.pdf"

strImagePath = "J:\\Documents\\expectedgrapgh.png"

objFile = JavaClasses.java_io.File.newInstance(strPDFPath)

objDoc = JavaClasses.org_apache_pdfbox_pdmodel.PDDocument.load_2(objFile);

 

 

arrPages = objDoc.getDocumentCatalog().getPages();

//var pageArray = pdfObject.getDocumentCatalog().getAllPages().toArray(); // Get the collection of pages

 

 

for(var i=1; i<=arrPages.getCount(); i++)

{

pageObj = objDoc.getPage(i);

arrofImages = pageObj.getResources().getImages().values().toArray();　//getting error at this line

imgMap = pageObj.getResources().getXObject();

imgArray = imgMap.values().toArray();

//imageObj = imgArray.items(imgIndex);

 

 

for(var j = 0 ; j < imgArray.length ; j++)

{

curImage = imgArray.items(p);

shankar_r :

> var curImage = arrofImages.items(p);

Wondering in what format the image is stored to the curImage variable? Is it Base64 encoded byte array or something else? Have you tried (and, hopefully succeeded in) to convert it to something compatible with TestComplete's Picture object?

    Below is the sample how i did image comparison with expected image and PDF image

     

    curImagePath = "c:\pdfimages/pdfimage1.png";

var curImage = arrofImages.items(p);
curImage.write2file_2(curImagePath );

var actualImage = Utils.Picture;
actualImage.LoadFromFile(curImagePath);

//Load the expected image
var expectedImage = Utils.Picture;
expectedImage.LoadFromFile(imagePath);


if(Regions.Compare(expectedImage,actualImage))
{ Log.Checkpoint("Passed");}else{
Log.Error("Failed");}

      I see, thank you a lot, Shankar!
      Format is handled internally by PDFBox. Sounds good for me.
