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, at FText[1],Length(FText));
     if ErrorCode0 then begin
       FLastErrorString:=FQR^.errtxt;
       exit;
     end;
   end;
end;
--------------------------

Note the "option_3" as DM_SQUARE setting.

Hello,

Can you be more precise ? Which kind of width & height ? With StrictSize checked the widget size would be 1x, 2x, 3x,...,Nx to fill as much as possible of the print space keeping pixels exactly as expected by the format so no "half pixel" dots appears. Non StrictSize can be used if the generated image would be big enought that non expected pixels (lines, "half pixel") will not affect the read capability (usually bigger than 4x original size).
