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...

I use below code to get images from PDF document, this may help you
var pdfObject = JavaClasses.org_apache_pdfbox_pdmodel.PDDocument.load_3(fileName);
var pageArray = pdfObject.getDocumentCatalog().getAllPages().toArray(); // Get the collection of pages
var curPage = pageArray.oleValue[1];//use page number here
var arrofImages = curPage.getResources().getImages().values().toArray();
for(p = 0 ; p < arrofImages.length ; p++)
{
var curImage = arrofImages.items(p);
}
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);
a) It might help if you let us know where the mentioned error occurs;

Unable to read pdf : “dotNET.org_apache_pdfbox_pdmodel.PDDocument” is null or not an object
http://community.smartbear.com/t5/Functional-Web-Testing/Unable-to-read-pdf-dotNET-org-apache-pdfbox-pdmodel-PDDocument/td-p/94722> 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.
Hi,
> which jar are you using. Mine is 1.8.13
https://community.smartbear.com/t5/TestComplete-Desktop-Testing/Compare-pdf-files/m-p/122418#M6672 link describes some differences between PDFBox version 1.8.x and 2.x and may help.
