[jira] [Commented] (PDFBOX-3523) PDFBox renders images 5 times
slower and bigger
[ https://issues.apache.org/jira/browse/PDFBOX-3523?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15547859#comment-15547859 ]
Tilman Hausherr commented on PDFBOX-3523:
-----------------------------------------
Please show the PDF, the old and the new code segment and explain what files you get that are "5 times bigger". Because "slower" I might believe, but not "bigger".

> Key: PDFBOX-3523
> URL: https://issues.apache.org/jira/browse/PDFBOX-3523
> Project: PDFBox
> Issue Type: Improvement
> Affects Versions: 2.0.3
> Environment: Java version 1.8
> Ubuntu Linux&Windows 10
> Reporter: Vasiliy Sadokhin
> Labels: performance
>
> We recently migrated PDFBox from 1.8.13 to 2.0.3. We found that it becomes 5 times slower to get a PDF page image and the image is 5 times bigger than PDFBox 1.8 did. For example, It took about 200ms and now it takes more than 1 second, the result size was less 200Kb and it's 1Mb now.
> We specified BufferedImage.TYPE_3BYTE_BGR for PDFBox 1.8 and we have no way to do it with 2.x. It might be a reason.
