[jira] [Comment Edited] (PDFBOX-4743) Long rendering time of fonts
in a specific PDF
[ https://issues.apache.org/jira/browse/PDFBOX-4743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17018294#comment-17018294 ]

Hi Tilman.
I have added two new PDFs. One without the instructions to set a font and write text. And the other one without drawing instructions for images.
Without images is slow, without text is fast.
Best regards

> Hi Team.
>
> We have found a PDF that takes a long time to render images.
>
> After some checking, we found that the one page takes more than 2 minutes to render, but if we remove the font information and render the PDF without text, it takes 3 seconds.
>
> Just looking at the font information, it doesn't seem to be a lot of data. 3-5kb per font and there are only about seven fonts defined. So there must be something else that complicates things.

> Best regards
