HI,
     I am generating a Qrcode via an API, which returns the Qrcode as a BMP file. This file a insert into a Scalerichview as per the function given below. After inserting, the this  image is seen as a dot. I am able to click this image and change the properties. After that is image is show correctly. I am using this in an editor. Ataching the properties image for reference. I understand this has something to do with the style may be.
The following is the function
procedure TTextEditorNewForm.InsertQrCode(cCertId:String);
var mStream : TMemoryStream;
    bmp     : TBitmap;
begin
  mstream  := TMemoryStream.Create;
  try
    IdHttp2.Get('http://172.16.15.10:5002/getcertificate/'+ cCertId,mstream);
    mstream.Position := 0;
    AdvPicture1.Picture.LoadFromStream(mstream);
    AdvPicture1.Picture.SaveToFile(ExtractFilePath(Application.ExeName)+'certid.bmp');
  finally
    FreeAndNil(Mstream);
  end;
  bmp := TBitmap.Create;
  bmp.LoadFromFile(ExtractFilePath(Application.ExeName)+'certid.bmp');
  with TextEdit.RichViewEdit do begin
    //AddTextNL(' ',rvsKeyword,0,0);
    AddTextNL(' ',rvsNormal,0,0);
    AddPicture('', bmp, -1);
    SetItemExtraIntProperty(ItemCount - 1, rvepImageHeight, 30);
    SetItemExtraIntProperty(ItemCount - 1, rvepImageWidth , 30);
    //AddTextNL(' ',rvsKeyword,0,0);
    AddTextNL(' ',rvsNormal,0,0);
    Format;
  end;
end;
Kindly help.
Thanks in advance

Obviously, it happens because not pixels, but twips or EMU are used as measure units, so 30 is a too small size.
Change the resizing code to:

Code: Select all

Re: QrCode Inserted as bmp
By the way, is smooth scaling OK for these QrCodes? Maybe I should add a property to an image item to disable smooth scaling?
