[jira] [Commented] (PDFBOX-4646) PDFToImage not working with certain formfields

["Tilman Hausherr (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-4646?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16926311#comment-16926311 ] 

Tilman Hausherr commented on PDFBOX-4646:
-----------------------------------------

The widget annotations have no appearance streams, that is why PDFBox doesn't show them. You could call {{doc.getDocumentCatalog().getAcroForm().refreshAppearances()}} to build them.

What really surprises me is that PDF.js shows them (although not in the correct color), because they don't generate missing appearance streams, or so I thought.

> Sometimes, PDFToImage would not render the values of PDF form annotation. I've attached the relevant files. The command I used is listed below. Note that I used a custom software to generate the form annotations in the pdf, but I have no problems viewing/editing the form fields in adobe reader, adobe acrobat, firefox, chrome, so I think this might be a bug in pdfbox. 
> java -jar pdfbox-app.jar PDFToImage -imageType jpg -dpi 140 cd_title_description_form.pdf
