[jira] [Commented] (PDFBOX-3353) Create appearance streams for
annotations
[ https://issues.apache.org/jira/browse/PDFBOX-3353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16445901#comment-16445901 ]
Tilman Hausherr commented on PDFBOX-3353:
-----------------------------------------
Work on PDFBOX-4199 made me have a closer look at the caret annotation AP. It is two Bézier curves, goes from bottom left, top middle to bottom right and then closes. The intermediate points are (horizontal middle, bottom) and (horizontal middle, vertical middle). /RD is created by Adobe Reader but it is unclear how it is calculated. The value has also an influence on the BBox, the matrix and the line width.
