Data Matrix Format is variable when increase Data Matrix data.
how to fix Data Matrix Format?

Hello,
Both Datamatrix are OK and well formed, unfortunatly there are many
options to generate some barcodes and I was unable to add much of them
due lack of time and there is no much people using the package and
maintain it is not, by now, a priority to me.
In order to generate the DataMatrix as you like it, squared, please open
the package source file "ubarcodes.pas", look for "procedure
TBarcodeDataMatrix.Generate" and change the function by this one:
---------------------------
procedure TBarcodeDataMatrix.Generate;
var
ErrorCode: integer;
begin
if Assigned(FQR) then begin
ZBarcode_Delete(FQR);
FQR:=nil;
end;
if Length(FText)>0 then begin
FQR:=ZBarcode_Create();
with FQR^ do begin
border_width:=1;
option_3:=DM_SQUARE;
end;
ErrorCode:=dmatrix(FQR,@FText[1],Length(FText));
if ErrorCode<>0 then begin
FLastErrorString:=FQR^.errtxt;
exit;
end;
end;
end;
--------------------------
Note the "option_3" as DM_SQUARE setting.
