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

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
