Subject [jira] [Commented] (PDFBOX-4310) Remove all images from a page
Date Tue, 04 Sep 2018 19:03:00 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-4310?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16603460#comment-16603460

Tilman Hausherr commented on PDFBOX-4310:
-----------------------------------------

You need to also remove the invoke ("Do") in the content stream (only if the name references
an image, and not a form xobject), have a look at the PDF with PDFDebugger. But I doubt you
will be happy with the result. For example, image "Im7" also contains the image of a text
"Internet & democracy". The Berkman logo is a combination of images and vector graphics.

> Hello Apache contributors,
> I am looking forward to remove all images from a pdf page (= create a new page without
images from the original)
> For the moment, I am trying the following and it is not working. What's missing?
> {code:java}
> PDPage page = document.getPage(p);             
> PDResources resources = page.getResources();             
> resources.getXObjectNames().forEach((cosName) -> {             
> PDXObject image; 
> try { 
>    image = resources.getXObject(cosName);             
>    if (resources.isImageXObject(cosName)) {   
>      resources.getCOSObject().removeItem(cosName);           
>      page.setResources(resources);            
>      page.getCOSObject().removeItem(cosName);             
>    }
> } 
> catch (IOException e) { }             
> });
> {code}
> Best, A.
