-----------------------------------------------------------
[~tilman] i emailed you the pdf since i could not find a sample 270 degree page
pdf that gets displayed as upright landscape.
i figure my problem is my quad coordinates. for portrait, it works correctly.
but if 270 degrees and i recalculate the quad coordinates, this is my code
LEGEND
-----------------
pos[0] = x
pos[1] = y
pos[2] = width
pos[3] = height
-----------------
and Util.transformY is a convenience method to convert my top y to lower y.
{code:java}
if (rotation == 270) {
// x,y = 1,2
quad[c++] = Util.transformY(pageSize, pos[1]) - pos[3];
quad[c++] = pageSize.getWidth() - pos[0] - pos[2];
// x,y = 3,4
quad[c++] = Util.transformY(pageSize, pos[1]);
quad[c++] = pageSize.getWidth() - pos[0] - pos[2];
// x,y = 5,6
quad[c++] = Util.transformY(pageSize, pos[1]) - pos[3];
quad[c++] = pageSize.getWidth() - pos[0];
// x,y = 7,8
quad[c++] = Util.transformY(pageSize, pos[1]);
quad[c++] = pageSize.getWidth() - pos[0];
}
{code}
