PageFormat pf = printerJob.pageDialog(printRequestAttributes);
if (pf != null) {
pageFormat = pf; // user selected OK
// more code
syncPrintRequestAttributes();
// more code
}Before all this I setup printRequestAttributes with the following code. Basically when I load an image with an aspect ratio that requires a portrait orientation and trigger the pageDialog the page margins are all 1 inch by default - what I would expect. If I then select landscape, the margins stay at 1 inch in the dialog.
However, if I load an image that requires a landscape orientation the margins start out at left=3.5, right=1.0, top=0.25, bottom=0.25. If I toggle portrait in the dialog I then get left=0.25, right=0.25, top=1.0, bottom=3.5.
Going back to loading a portrait image, if I select landscape, then click the OK button in the dialog, I now get the same margin values and behavior as the paragraph above. Can anyone explain what is going on here?
I think for some reason I am unable to set in printRequestAttributes
As an aside, the accuracy gets skewed because the class MediaPrintableArea is implemented in int microns and the rest of Graphic2D is implemented in int 1/72 inches.
