[jira] [Commented] (PDFBOX-2849) implement appearance generation
for buttons
[ https://issues.apache.org/jira/browse/PDFBOX-2849?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14609048#comment-14609048 ]
Maruan Sahyoun commented on PDFBOX-2849:
----------------------------------------
For existing PDButton fields PDButton fields an appearance generation shouldn't be necessary as 'only' the correct appearance has to be set for display as can bee seen by the above code. Appearance generation when setting a value is only necessary for variable text fields.
