Consider using GrijjyDeployMan to add multiple files, you can add an entire folder instead of files by files.

All I actually want is to draw text that is orientated 90 degrees to the horizontally, ie vertical. No fancy paths to follow, just a straight line. I can currently do it by rotating the image first by 90 degress, writing the text horizontally, then rotate the image back -90 degrees.

The correct way is to rotate only the drawing you are doing, in this case the text. For this you must rotate by ISkCanvas:

uses
  System.Math, System.Math.Vectors, Skia;

procedure TForm1.SkPaintBox1Draw(ASender: TObject; const ACanvas: ISkCanvas;
  const ADest: TRectF; const AOpacity: Single);
var
  LDest: TPointF;
begin
  LDest := PointF(150, 50);
  ACanvas.Clear(TAlphaColors.Null);
  ACanvas.Save;
  try
    ACanvas.DrawSimpleText('Skia4Delphi 1', LDest.X, LDest.Y, TSkFont.Create, TSkPaint.Create);
    ACanvas.Rotate(90);
    LDest := LDest * TMatrix.CreateRotation(DegToRad(-90));
    ACanvas.DrawSimpleText('Skia4Delphi 2', LDest.X, LDest.Y, TSkFont.Create, TSkPaint.Create);
  finally
    ACanvas.Restore;
  end;
end;

Results:

Note: I made the adjustment of LDest with TMatrix.CreateRotation because when rotating the canvas, its X and Y of DrawSimpleText are also rotated.

@hsauro  What exactly do you want to do? Draw text around a circle? Do you have any image of what it would be like? Drawing text along a path is not trivial, but depending on what it is, we can try to make a non-morphing example, just using letter rotation.

Fix: I think he meant below Professional (Starter, Community and Trial).
I looked at each Feature Matrix of the RAD Studio versions and questioned him, the compilation via command line feature varies a lot from version to version including from update to update. Some in the Starter edition only have the command line for Win32, others not even for Win32.

@TimCruise Now all makes sense! Your installation did not generate dcus or bpls because Delphi 10.4.2 CE does not allow compilation via command line. We will solve this problem in the next version. Thank you so much for reporting.

One of the embardero consultants informed me here that neither the Comunity Edition nor the Professional version has the compilation via command line. He even said he's not sure, but he doesn't think even the trial version has it.

This is definitely too bad.

10.4.2 community edition does not have the command line compiler (10.3 did)

I did not know. Doesn't work even using msbuild? Even just for win32?

I believe that for general purposes, a great image format option would be WebP. It has the same performance as PNG but compresses 30% more in lossless mode. In lossy mode, it compresses 30% more than jpeg (with same quality) and still allows transparencies. It is a format that also allows animated images such as gif. It is supported by all browsers, many softwares, and even Windows 10 already displays thumbnails in folders.

As for the future, I would bet on Heif. There are already many libraries that support it but most in beta mode, like skia.

Compatibility is very important, I wouldn't bet on a format that image editors, viewers or browsers can't open.

I'm preparing a new demo right now. It will also be part of the next release.

The installer should have done this, it's working fine for dozens of developers. Something is blocking the build during installation, maybe an antivirus. Maybe you have run as administrator (which is not necessary) and windows defender blocked the build... Anyway, in a few weeks we will have a new version with a new installer and a code certificate that will avoid these blocks.

Ok. In the previous folder also does not have any files? "Skia4Delphi\Library\Delphi10Sydney\Win32\Release\"

If you don't have any files either, check your rsvars.bat, "C:\Program Files (x86)\Embarcadero\Studio\22.0\bin\rsvars.bat", if it contains the same content:

@SET BDS=C:\Program Files (x86)\Embarcadero\Studio\21.0
@SET BDSINCLUDE=C:\Program Files (x86)\Embarcadero\Studio\21.0\include
@SET BDSCOMMONDIR=C:\Users\Public\Documents\Embarcadero\Studio\21.0
@SET FrameworkDir=C:\Windows\Microsoft.NET\Framework\v4.0.30319
@SET FrameworkVersion=v4.5
@SET FrameworkSDKDir=
@SET PATH=%FrameworkDir%;%FrameworkSDKDir%;C:\Program Files (x86)\Embarcadero\Studio\21.0\bin;C:\Program Files (x86)\Embarcadero\Studio\21.0\bin64;C:\Program Files (x86)\Embarcadero\Studio\21.0\cmake;C:\Users\Public\Documents\Embarcadero\InterBase\redist\InterBaseXE7\IDE_spoof;%PATH%
@SET LANGDIR=EN
@SET PLATFORM=
@SET PlatformSDK=

What files have in your folder "Skia4Delphi\Library\Delphi10Sydney\Win32\Release\", after installation?

@TimCruise You will have to remove these two registries and reinstall skia4delphi. But to be sure, follow the steps:

1) Uninstall via GetIt (if you haven't already)

2) With your RAD Studio closed, delete these two skia records in "HKEY_CURRENT_USER\SOFTWARE\Embarcadero\BDS\21.0\Disabled Packages"

3) Go to Windows Configurations > Applications > search for Skia4Delphi (if found, uninstall it with your RAD Studio closed).

4) Check if the file "C:\Users\Public\Documents\Embarcadero\Studio\Skia4Delphi\unins000.exe" exists, if so, run it to uninstall.

5) Install the Skia4Delphi running the "Skia4Delphi_2.0.1_Setup.exe", because some uses have reported problems using out GetIt package in Sydney. In setup's platforms screen, select just the platforms that your IDE is already to compile.

6) After installation, try to run our sample "skia4delphi\Samples\Basic\FMX\Skia4Delphi_Basic.dproj"

Yes, my brother and I are the authors.

I even do not see this Skia menu item:

https://raw.githubusercontent.com/viniciusfbb/skia4delphi/main/Assets/Documents/enabling_project_dark.png

Right. I suspect that some unsuccessful install is hampering new installs, but I need more information:

1) Did you install only using installer (Skia4Delphi_2.0.1_Setup.exe) or did you try another method (GetIt or manual)?

2) Was there an error during an installation? If so, do you still have the Build.Logs.txt that is generated in the folder you installed skia4delphi in?

3) Access RegEdit.exe, and take a screenshot of "HKEY_CURRENT_USER\SOFTWARE\Embarcadero\BDS\21.0\Known Packages" and "HKEY_CURRENT_USER\SOFTWARE\Embarcadero\BDS\21.0\Disabled Packages".

I partially solve it.

I deselect the Win32 option and there is no more error. 

Very strange. If you find any problems during use, open an issue so we can investigate further.

Just reinstall the Skia4Delphi and the new platform will be available at installation.

And now, I am still facing these 2 errors after I have installed Skia from within RAD Studio.  How do I correct them?  

 

Now that's a mistake. Probably the folder you are installing requires administrator permission and you have not run the installer as an administrator.

The solution in this case is to uninstall and install in the default folder that the installer suggests (does not require admin permission).

@TimCruise 

There is but you need a macOS to install the SDK in your RAD Studio. It's even possible to run macOS on windows with VMWare, but that's probably illegal.

Anyway, with the SDK installed you'll only be able to compile, the simulator doesn't work, you'll have to have an iPhone too.

Without the SDK, you won't even be able to compile a blank project for the platform you want.

About the Skia4Delphi installer, basically it checks if it is possible to compile for the platform, so if your delphi is really ready to compile for the platform, then yes it will appear available to be selected in its installation.

@TimCruise

The installer automatically detects the platforms installed in your RAD Studio. Platforms that are disabled are those that have not yet configured the SDK in your IDE.

Install the SDK of the platform you want on your delphi and then reinstall Skia4Delphi.

Hello. I adapted your test with Skia4Delphi to directly access the pixels instead of painting the pixel. The result was 45 ms on win64.

procedure TfrmMain.Button3Click(Sender: TObject);

  procedure DrawMandelbrotPixmap(APixmap: ISkPixmap; X, Y, au, bu: Double; X2, Y2: Integer);
  var
    c1, c2, z1, z2, tmp: Double;
    i, j, Count, rgb: Integer;
    hue, saturation, value: Double;
  begin
    c2 := bu;
    for i := 10 to X2 - 1 do
    begin
      c1 := au;
      for j := 0 to Y2 - 1 do
      begin
        z1 := 0;
        z2 := 0;
        Count := 0;
        // count is deep of iteration of the mandelbrot set
        // if |z| >=2 then z is not a member of a mandelset
        while (((z1 * z1 + z2 * z2 < 4) and (Count <= 50))) do
        begin
          tmp := z1;
          z1 := z1 * z1 - z2 * z2 + c1;
          z2 := 2 * tmp * z2 + c2;
          Inc(Count);
        end;
        // The color depends on the number of iterations
        hue := count / 50;
        saturation := 0.6;
        value := 0.5;

        PCardinal(APixmap.PixelAddr[i, j])^ := HSLtoRGB(hue, saturation, value);
        c1 := c1 + X;
      end;
      c2 := c2 + Y;
    end;
  end;

var
  au, ao: Double;
  dX, dY, bo, bu: Double;
  LWidth: Integer;
  LHeight: Integer;
  LTimer: TStopwatch;
  LBitmap: TBitmap;
  LSurface: ISkSurface;
begin
  LTimer := TStopwatch.StartNew;
  LWidth := Image1.Width;
  LHeight := Image1.Height;
  LSurface := TSkSurface.MakeRaster(LWidth, LHeight);

  LBitmap := TBitmap.Create(LWidth, LHeight);
  try
    ao := 1;
    au := -2;
    bo := 1.5;
    bu := -1.5;
    // direct scaling cause of speed
    dX := (ao - au) / (LWidth);
    dY := (bo - bu) / (LHeight);
    DrawMandelbrotPixmap(LSurface.PeekPixels, dX, dY, au, bu, LWidth, LHeight);
    LBitmap.SkiaDraw(
      procedure (const ACanvas: ISkCanvas)
      begin
        ACanvas.DrawImage(LSurface.MakeImageSnapshot, 0, 0);
      end);
    Image1.Picture.Assign(LBitmap);
  finally
    LBitmap.Free;
  end;

  Showmessage(LTimer.Elapsed.TotalMilliseconds.ToString+' ms');
end;

However, your benchmark isn't accurate, you're basically changing pixel by pixel, it's not a good way to measure drawing library performance.

Also, tasks that change an image pixel by pixel almost always perform better by creating a shader to run on the GPU. This is another advantage of Skia4Delphi, as it allows you to create shaders at runtime through the Skia Shader Language (based on GLSL). Even now I'm preparing a VCL sample of an animated shader, see the performance:

Currently skia4delphi closed beta supports gif on all platforms. The next release will be available in 2 weeks.

Eric, what version of your PAServer? Is it 13.0.12.0? I couldn't confirm it, but someone reported in a whatsapp group that the PAServer patch 1 link on my.embarcadero.com is the link of the old version, 13.0.11.9...

So if that's your case, install the patch via getit and use the new PAServer which will be in the RADStudio directory.

I never worked with grpc but, AFAIK, you should use a client thats support http/2, and put in body the generated protocol buffer based on .proto file of the api service. You can make a delphi record based on .proto struct and use the Erik Van Bilsen serialization code https://github.com/grijjy/GrijjyFoundation/blob/master/Grijjy.ProtocolBuffers.pas
 

@Hans♫ I couldn't simulate your problem. I set up the same scenario you described in a blank project and the scroll worked perfectly. I also mounted on a TVertScrollBox and it worked perfectly. I'm using RAD Studio 11, but it works the same as in previous versions. Try simulating on a blank project to see where the problem is. I don't know what's going on, but maybe some other control is capturing the gesture...

This is strange because the scrollbox does not use mousedown, mouseup, it uses gestures, and with hittest or without hit test in the components above, it should work in the same way.
