I've looked at the scanline demo and it works fine on Mac OS X.
My question is when I try to use the code in my project using Delphi
compatability mode, I get the error listed below...
var
lRow : Pointer;
ScanLineImage : TLazIntfImage;
begin
for j := 0 to Height - 1 do
begin
lRow := ScanLineImage.GetDataLineStart( j );
i := 0;
while ( i < Width - 1 ) do
begin
PByte(lRow)[i] := 0; // Error : Array type required
end;
end;
end;
Why and is there a fix for this?
in objfpc mode you can access any typed pointer as an array like:
var
p: PWord;
begin
...
p[someindex] := 12345;
Should I define lRow as a PByteArray?
In delphi mode, Yes.
Unless you want to compile this in Delphi, there is no reason to use
delphi mode. You can, if needed, use a different mode per unit.
