@Alexander Halser A few years ago I made a tutorial on how to explore iOS app crash, but the same applies to macOS as well. Take a look especially at Step 4 - Symbolizing the crash file.

@Riku23 Can you attach a demo? Are you using Skia? I’m asking this because Skia is rendering its own filters on RAD 12+, so you can get different results when Skia is enabled. Let me know if this is the case.

@John van de Waeter The performance with Skia was improved on RAD Studio 12.2. Also, the property Form.Quality affects the performance when Skia is enabled. Note: I recommend delete your project dcu output folder as it may contain old versions of Skia4Delphi from the open-source installation.

Seems related to “Display zoom” option of iOS. Issue reported here: https://github.com/skia4delphi/skia4delphi/issues/315

@XylemFlow are you using GlobalUseSkia := True;?

Also, the adaptive icon files, and all artwork generated files, are available at your project folder, in the subpath “.\<ProjectName>.Artwork\”. It is important to note that the adaptive icon and the vectorized splash are only generated when you use and SVG on the input of icon fields of the artwork generator. That is, if you use PNG image, it will generate all icons and splashs but not the android adaptive icon and android vectorized splash. If you found a real issue in the IDE and you have the steps to reproduce, please create a Jira for it, to improve future versions.

Try add GlobalUseMetal := True; on your dpr. iOSSim has one know issue related to OpenGL.

@Hans♫ I think that could be a Google Skia limitation or issue, so the right place to report bugs is on https://issues.skia.org/, instead on QP. However, I have already opened a new conversation in the Skia group to obtain more information about this: Poor quality of anti-aliasing on NVidia GPU (google.com)

@Hans♫ I used the same code you provided and got satisfactory results. Look: <No Skia> | <Skia + Vulkan> (Scale 100%) It is difficult to deduce what is happening if the same code is producing different results. That's why I think it would be interesting if we could test it on more machines. The project I used is attached: testVulkan.7z

@Hans♫ Do you have a blank project simulating this? I drew directly in the form's OnPaint using your example on a blank project and got the same result for all renders, except for the FMX GPU without Skia which seems to be bugged. scale 1x: scale 2.25x:

@Hans♫ Is this an image or a path? (we have to understand if the arrow is being drawn or resized) Can you share the source of this icon?

@Hans♫ Please check your Form.Quality because the AntiAlias is direct related to the current form quality: https://github.com/skia4delphi/skia4delphi/blob/093ec41b1b951c68cbccaa885a84c19242e09fb7/Source/FMX/FMX.Skia.Canvas.pas#L1571 The AntiAlias of raster is forced to be always true because some preliminar tests proved to be apparently faster.

@Stefan Glienke Could you add a version constant to Spring.pas? Something like: const Spring4DVersion = 2.0; to help us maintain code compatible with 1.x and 2.0 at the same time, as it would allow: {$IFNDEF DELPHI_12_UP} constructor THashSet<T>.Create(ACapacity: NativeInt); begin {$IF defined(Spring4DVersion) and (Spring4DVersion >= 2)} inherited Create(ACapacity, nil); {$ELSE} inherited Create; {$ENDIF} end; {$ENDIF} This is especially important for large teams/projects that share common code, where some projects and people use version 1.x while others use version 2.x, and the common code should support both.

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...

Hi @martincg! I answered you on another topic with the same issue. To preserve the old content of the bitmap when starts draw with skia, you should call Bitmap.SkiaDraw(..., False);

@martincg Bitmap.SkiaDraw have a second optional argument, AStartClean: Boolean, and when False you will not lost its content.

1) Enable Skia on your project (right click on project > Enable Skia; 2) GlobalUseVulkan on FMX.Types is default True on Android, so it will use Skia Vulkan on Android by default;

The current design of Vcl's TCanvas makes it unfeasible to create a wrapper that uses different libraries / different outputs. There is already a request to try to improve this and you can vote: [RSP-43149] Remodel TCanvas to allow injection of a different drawing backend - Embarcadero Technologies So currently, what can be done is to draw using the APIs directly from Skia, that is, using the document's SkCanvas, or you can draw in a TBitmap in the conventional Vcl way and in the end use: SkCanvas.DrawImage(Bitmap.ToSkImage, 0, 0); but I don't recommend this because you wouldn't have a vectorized PDF, and the texts couldn't even be selected/copied, as the PDF would be an image in fact.

From what I saw here, the bad quality seems to be only in the preview control. The output images are in good quality.

@PeterPanettone Please, report that on Quality Portal, it is an issue and should be fixed. As a "workaround", I strongly recommend using SVG: Radioactive SVGs which is working perfectly.

When you Run the app by the IDE, it will share the PATHs of the IDE with your program. IOW, in a project without Skia enabled, using skia controls, if you click on Run on the IDE, it will work fine (because the IDE have on it own PATHs the path to the sk4d.dll), but if you run the Project1.exe on the Windows Explorer, it will crash on startup due the lack of the sk4d.dll.

Additional info: On RAD 12 it is possible to encode animated WebP (better format than GIF). See DocWiki.

Maybe you have the "Webp Image Extensions" installed: https://apps.microsoft.com/detail/9PG2DK419DRG

Yes, this is relevant only for the .aab generation. Note: you can’t change the ‘condition’ on IDE side, you should open the dproj and add it manually. See one dproj with that: https://github.com/skia4delphi/skia4delphi/blob/eed4afbf8a34137a9bfa308bcb5ef87cee84abcb/Samples/Demo/FMX/Projects/RAD%20Studio%2011%20Alexandria/Skia4Delphi.dproj#L1182

Did you configure the paths in Tools > Options > Deployment > SDK Manager?
