Only in the 1.1 development compiler. The 1.0 compiler doesn't support

Qword is 64 bit, that will not work, but Cardinal (=DWord) should work.
But you can just as well use the 'pointer math' approach and declare
tQPixelArray = ^tQPixel;
Arr : TQPixelArray;
will do what you expect. Only the memory management you must do
