  1. Is anyone managing to use the storyboard launch screen? Here it is only working with the original delphi color and image. When I try to change the background color or the image in the project options, it has no effect.

    Copy deployment across platforms

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

    Skia4Delphi

    Website: github.com/viniciusfbb/skia4delphi Skia4Delphi is a cross-platform 2D graphics API for Delphi based on Google's Skia Graphics Library (skia.org). Google's Skia Graphics Library serves as the graphics engine for Google Chrome and Chrome OS, Android, Flutter, Xamarin, Mozilla Firefox and Firefox OS, and many other products. Skia provides a more robust Canvas, being very fast and very stable, with hundreds of features for drawing 2D graphics, in addition to a text shaping engine designed to render texts in the most diverse languages with right-to-left support (such as the Persian language), full support for loading SVG files, support for creating PDF files, support for rendering Lottie files (verotized animations created in Adobe After Effects), integration with the GPU, among countless other cool features. Skia's idea is similar to Firemonkey's, the same codebase used in an OS will work the same on other platforms. It is also possible to design using the CPU in independent background threads. Skia also has native codecs, of course if you don't use the SKCodec class, when loading an encoded image it will give priority to using the platform's native codec, but it is possible to use its codec, for example for jpeg files it uses libjpeg-turbo and for png files libpng which maybe in certain environments may perform better than native. See some examples: Advanced shapes Advanced text rendering / shaping Svg Lottie files And much more...

    Skia4Delphi

    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.

    Skia4Delphi

    @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.

    Your Delphi verion does not support COMMAND

    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.
  7. @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.

    Your Delphi verion does not support COMMAND

    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.

    Your Delphi verion does not support COMMAND

    I did not know. Doesn't work even using msbuild? Even just for win32?
  10. 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.
  11. I'm preparing a new demo right now. It will also be part of the next release.
  12. 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.
  13. 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=
  14. What files have in your folder "Skia4Delphi\Library\Delphi10Sydney\Win32\Release\", after installation?
  15. @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"
  16. Yes, my brother and I are the authors. 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".
  17. Very strange. If you find any problems during use, open an issue so we can investigate further.
  18. Just reinstall the Skia4Delphi and the new platform will be available at installation.
  19. 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).
  20. @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.
  21. @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.

    Skia versus VCL for plotting points

    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: 27.11.2021_01.05.45_REC.mp4 27.11.2021_01.05.45_REC.mp4

    iOS 15.1

    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.

    how to cosume grpc in delphi vcl client?

    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
