Marcus Korinth created PDFBOX-5809: -------------------------------------- Summary: PDDocument#importPage slowed down by factor 1300 Key: PDFBOX-5809 URL: https://issues.apache.org/jira/browse/PDFBOX-5809 Project: PDFBox Issue Type: Bug Affects Versions: 3.0.2 PDFBox Reporter: Marcus Korinth
We are using the *PDDocument#importPage* Method in our own splitter where we split pages from a _SourceDocument_ to a _TargetDocument_. In order to do so we first extract the page by using the following code: {code:java} final PDPage sourcePage = sourceDocument.getPage(pageNumber); {code} Immediatly afterwards we are calling: {code:java} final PDPage targetPage = targetDocument.importPage(sourcePage); {code} This approach worked just fine with *pdfbox 2.0.26*. We decided to upgrade to version *3.0.2* since it takles a lot of the problems. Unfortunately the *PDDocument#importPage* method slowed down by around 1300 times. In Version *2.0.26* it took 15ms in an average. With the latest *3.0.2* it takes 20000 ms in average. That is a huge deal breaker as we usually have to split documents which have several thousand pages. Note: The same applies when using *PDDocument#addPage*. Note: The problem does not appear in *3.0.1*. But we can't use that since it has other major problems which breaks our application. I have prepared an example document with which you can replicate the issue. Due to the file size limitation I had to prepare a WeTransfer-Link for you: https://we.tl/t-lfN2wz7cAs -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@pdfbox.apache.org For additional commands, e-mail: dev-h...@pdfbox.apache.org
