    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...

    Determining text width

    Anyone know of a better way to determine the width as it would be displayed. Canvas.TextWidth is consistently giving back too a value that is around 15-20% too small. I'm using this in a custom control and have assigned the control's font to the canvas.. all to no avail. I have spent at least an hour searching for answers to this but got nowhere. I feel like I must be missing something obvious?

    Draw TBitmap

    I want to insert a bitmap on it's own left side again using canvas.drawbitmap function but actually this code does not do anything..... can't see my mistake here 😞 procedure InsertonMyleft(aBMP : TBitmap); var tempBMP: TBitmap; RecFull: TRectF; RecLeft: TRectF; begin tempBMP := TBitmap.Create; try aBMP.Canvas.BeginScene; tempBMP.Assign(localBMP); tempBMP.SaveToFile('c:\temp\debugme.bmp'); RecFull := RectF(0, 0, aBMP.Width, aBMP.Height); RecLeft := RectF(0, 0, round(aBMP.Width / 3), round(aBMP.Height / 1)); aBMP.Canvas.DrawBitmap(tempBMP, RecFull, RecLeft, 50, True); aBMP.Canvas.EndScene; aBMP.SaveToFile('c:\temp\debugme2.bmp'); finally tempBMP.Free; end; end;
