Hi

Hi,

I used to manipulate 8bit bitmap scanlines and pixels in the folowing way.

type
PConstRGB8s = ^TConstRGB8s;
TConstRGB8s = Packed Array[0..cMaxPixelWidth-1] of Byte;
TPConstRGB8sArray = Packed Array of PConstRGB8s;


.....
var
aScanlines : TPConstRGB8sArray;

....

Setlength( aScanlines, bmp.Height);
for i:=0 to bmp.Height-1 do
aScanlines[i] := bmp.Scanline[i];

...
someByteValue := aScanLines[0]^[0]; // access violation here in Win64


It works fine in win32 plateform.

Then I compile it in win64, show no error.
But after I run it, it show accees violation when step into "someByteValue := aScanLines[ay]^[ax];";

Can someone help?

Thanks.

Daniel
