    DIgital sign of pdf

    Hello,

    I think you should find (or develop) and install a browser plugin that specializes in this.
    And additionally use JS libraries that work with cryptography.

    Many web apps allow the user to select a digital certificate and to do some operations, even signing documents.

    I need to do it without installing anything in client side. I'll keep searching.

    Regards

    Hello

    I need to implement a process to add a digital signature to an existing PDF. The user must be able to select a local certificate (in client machine) and the app must sign the pdf file with this certificate.

    Thanks in advance

    uniChart Set Color On BarSeries

    in General

    Posted

    I have two bar series created in design. Not stacked.
    If I assign different brush colors C1 and C2 to them, when running, all bars in both series appear with color C1.
    It does not work assigning colors in design time nor in run time.
    And in the legend still appear original colors.

    Thx in advance

    With the latest builds I couldn't reproduce. Can you please upgrade to the latest builds?

    Sorry, but now I have 3 apps in production and upgrading suposes to buy a license renovation, plus rebuild and review all apps.

    Probably I'll update Unigui after this summer.

    Thanks anyway.

    Please repeat the "Generate Data" button and click each time on first "Get Image" Button.

    If you don't see rubbish (in Y labels) and overlapped bars in image (like in this image), then we can be sure that the problem is in the Unigui/Sencha version. In this case I'd like to know if I can patch just this component, so I can not update my Unigui version by now.

    I'm using Unigui 1.0.1424 (proffesional, registered to  atorregrosa@tricom.es) and Delphi 10.3.

    PD The Second "Get Image" button was for testing if I can get the image directly from object, but it only works in client side, not in server side (and I can't change the filename and destination folder).

    Thx in advance

    Hello. Here you are a simple sample: A chart, two series (Bars), a UniImage and two buttons. Rubbish appear when series has less records than previous.

     

    unit Main;

    interface

    uses
      Windows, Messages, SysUtils, Variants, Classes, Graphics,
      Controls, Forms, uniGUITypes, uniGUIAbstractClasses,
      uniGUIClasses, uniGUIRegClasses, uniGUIForm, uniButton, uniChart, uniImage,
      uniGUIBaseClasses, uniPanel;

    type
      TMainForm = class(TUniForm)
        UniChart1: TUniChart;
        UniImage1: TUniImage;
        UniBarSeries1: TUniBarSeries;
        UniBarSeries2: TUniBarSeries;
        UniButton1: TUniButton;
        UniButton2: TUniButton;
        procedure UniButton1Click(Sender: TObject);
        procedure UniChart1ChartImage(Sender: TUniCustomChart; Image: TGraphic);
        procedure UniButton2Click(Sender: TObject);
      private
        { Private declarations }
      public
        { Public declarations }
      end;

    function MainForm: TMainForm;

    implementation

    {$R *.dfm}

    uses
      uniGUIVars, MainModule, uniGUIApplication;

    function MainForm: TMainForm;
    begin
      Result := TMainForm(UniMainModule.GetFormInstance(TMainForm));
    end;

    procedure TMainForm.UniButton1Click(Sender: TObject);
    var t, q : integer;
    begin
        UNiChart1.SeriesList[0].Clear;
        UNiChart1.SeriesList[1].Clear;
        t:=random(10)+1;
        for q:=1 to t do begin
          UNiChart1.SeriesList[0].Add(random(100),inttostr(q));
          UNiChart1.SeriesList[1].Add(random(100),'');
        end;
    end;

    procedure TMainForm.UniButton2Click(Sender: TObject);
    begin
        UniChart1.SaveImage;
    end;

    procedure TMainForm.UniChart1ChartImage(Sender: TUniCustomChart; Image: TGraphic);
    begin
        UNiImage1.Picture.Assign(Image);
    end;

    initialization
      RegisterAppFormClass(TMainForm);

    end.

    I attach some screen captures. Please note that in screen chart appears right, but when I generate PNG by saveimage procedure this file has "rubbish".

    I have several apps in production, so I don't want to upgrade unless I am sure this error is fixed.

    Chart #1 (screen) - 2 series, 3 records

    image.thumb.png.4871c6f0faecd2850b9718b266c5836d.png

    Chart #1 (PNG image)

    image.png.be722a1f717d47075084aaa3a5d8b08a.png

    Chart #2 (screen) - 2 series, 1 record

    image.thumb.png.6ca4a7d03066e0b365977accae64a852.png

    Chart #2 (PNG) - Here you can see "rubbish" from previous chart (in bars and in left vertical axis)
