Hi all, A generic question. I'm deploying my apps with an embedded SQLite DB. Each time I compile/deploy, that existing on device DB file is overwritten by the default one. It's fine for development. But how do you actually proceed if you want to deploy an update? If a user has the app already with personal data, I don't want her/him to lose that data. Testing whether the DB already exists is not possible since it's deployed each time within the new binary. One way would be to have all the code to check whether the DB exists. If not, programmatically create it and fill it with sample data. If it does, just check its version and apply possible structure upgrades? But it feels like this would embark a lot of code that may not really be useful. How do you guys deploy news versions of your apps without overwriting exists DBs? I especially think about iOS and Android devices. Thanks for any light. Steve
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...
angusj posted a topic in I made thisImage32 is a 2D graphics library written entirely in Delphi Pascal. It provides an extensive range of image manipulation functions and includes a polygon renderer that supports a wide range of filling options.
