PDF keep the TrimBox after PDF rotation - itext

Question

I´ve came across a challenge of creating a trimbox in a PDF with portrait orientation and them rotate it to the landscape orientation, that i did.
pageDict.put(PdfName.ROTATE, new PdfNumber(rot + 270));
But my trimbox goes banana. When i define it again with the same coordinates and with the rotation that i defined the trimbox have the same look (perimeter) but the isn´t in the same place.
I´ve tried to define the trimbox calculating the new coordinates but the calculation don´t make much sense, because the calculations (supposed) are ok but the trimbox don´t appear in the place that was defined in the portrait orientation.
Say that i want to define a trimbox in portrait, say that inside is a picture, and when i rotate the page the trimbox continues to involve the same picture, how can this be done?
Anyone have any idea?
cheers
UPDATED:
This is the original TrimBox setted:
This is the TrimBox after doing the rotation of the PDF page:
What i want is to set keep the same TrimBox and in the same place independent if the page is rotated or not.
Cheers
UPDATED:
The rotation of the PDF is in the original POST.
The definition of the TrimBox is made by BIRT with a changed API made by us that defines the boxes, one is TrimBox and is made like this:
PdfArray array = (PdfArray) pageDict.get(PdfName.TRIMBOX);
PdfRectangle trimBox = new PdfRectangle(Float.parseFloat(array.getArrayList().get(0).toString()),Float.parseFloat(array.getArrayList().get(1).toString()),Float.parseFloat(array.getArrayList().get(2).toString()), Float.parseFloat(array.getArrayList().get(3).toString()));
pageDict.put(PdfName.TRIMBOX, trimBox);
About providing the files, i can´t because Stack don´t let me (need at least 10 reputation).
Cheers

I just compared the two files you provided in Adobe Acrobat. And it appears that the PDFs are just as they should be.
Test_Original.pdf:
Entries in page dictionary:
/MediaBox [0, 0, 666.29, 912.89]
/TrimBox [22, 22, 600, 400]
/BleedBox [22, 22, 600, 400]
/ArtBox [22, 22, 600, 400]
In Adobe Acrobat:
Test_After_ROTATED.pdf:
Entries in page dictionary:
/TrimBox [22, 22, 600, 400]
/MediaBox [0, 0, 666.29, 912.89]
/BleedBox [22, 22, 600, 400]
/ArtBox [22, 22, 600, 400]
/Rotate 270
In Adobe Acrobat:
Thus, everything is just fine, only the rotate was added in the page dictionary and, therefore, everything (including the trim box) is rotated.
Thus, I assume the program you use to display the trim box is somewhat limited when rotation is part of the game.
You mentioned BIRT. Maybe BIRT has its own set of information concerning the trim box stored somewhere else (according to the screenshots you used to have in your question with distances from top, left, right, and bottom). In that case those information might also have to be updated when rotating the PDF.
Or, as you use a changed API made by you that defines the boxes, maybe that API has to be told about rotation effects?
