maltaisn closed PDFBOX-4853. ---------------------------- Fix Version/s: 3.0.0 PDFBox Resolution: Fixed > PDPageContentStream doesn't extend PDAbstractContentStream > ---------------------------------------------------------- > > Key: PDFBOX-4853 > URL: https://issues.apache.org/jira/browse/PDFBOX-4853 > Project: PDFBox > Issue Type: Improvement > Reporter: maltaisn > Priority: Minor > Fix For: 3.0.0 PDFBox > > > Hi, > > I'm not sure if this is the right place to post this. I tried the FAQ mailing > list 2 weeks ago and didn't get any response so I'll try here. > > I'm creating a PDF with transparency groups so I need to use > PDFormContentStream, but also PDPageContentStream when not drawing to a > transparency group. Transparency groups can be arbitrarily nested so I keep a > stack of the current content stream to know which one to write to. > > However, what prevents me to keep the stack is that PDPageContentStream and > PDFormContentStream have no common interface despite sharing nearly all the > same methods. Is there any reason for this? I see there's already > PDAbstractContentStream that's being implemented by PDFormContentStream, > PDAppearanceContentStream PDPatternContentStream, but not by > PDPageContentStream... Why? > Currently this forces me to do [something like > that|https://pastebin.com/p2FJw6GN] (Kotlin code) to artificially create an > interface for both. It's pretty ugly. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@pdfbox.apache.org For additional commands, e-mail: dev-h...@pdfbox.apache.org
