[OpenJDK 2D-Dev] Clarification regarding PageFormat and Paper getImageable* functions orientation consideration

Hi all,


I am working on https://bugs.openjdk.java.net/browse/JDK-8203395  and this bug is about "PageFormat showing wrong printer margins in LANDSCAPE orientation" .

Application code it trying to print in Landscape and Portrait but both show same margins:

Margins default : 12,12,17,17
Margins OrientationRequested.LANDSCAPE : 12,12,17,17

The code of the application uses Paper object for getting margins :

PageFormat pf = printerJob.getPageFormat(aset);

       Paper paper = pf.getPaper();

       long paperTopMargin = Math.round(paper.getImageableY());
       long paperLeftMargin = Math.round(paper.getImageableX());
       long paperRightMargin = Math.round(paper.getWidth() - paper.getImageableWidth() - paperLeftMargin);
       long paperBottomMargin = Math.round(paper.getHeight() - paper.getImageableHeight() - paperTopMargin);

When I looked at the latest JDK code, PageFormat getImageable functions are taking into account Orientation and Paper getImageable functions are not , and hence we see the same output.

Using Page format object instead of Paper shows the correct output:

Margins default : 12,12,17,17
Margins OrientationRequested.LANDSCAPE : 17,17,12,12


My question is that should Paper getImageable* functions also need take into account orientation as per spec ?, or is the current behavior of them not considering orientation correct and why ?
