While the clipping logic was correct (current v/s new clipping path), the clipping path contents weren't. This commit fixed that. We calculate the clipping path in two places: when we set it to be the whole page at graphics state creation time, and when we perform clipping path intersection to calculate a new clipping path. The clipping path is then used to limit painting by passing it to the painter (more precisely, but passing its bounding box to the painter, as the latter doesn't support arbitrary path clipping). For this last point the clipping path must be in device coordinates. There was however a mix of coordinate systems involved in the creation, update and usage of the clipping path: * The initial values of the path (i.e., the whole page) were in user coordinates. * Clipping path intersection was performed against m_current_path, which is in device coordinates. * To perform the clipping operation, the current clipping path was assumed to be in user coordinates. This mix resulted in the clipping not working correctly depending on the zoom level at which one visualised a page. This commit fixes the issue by always keeping track of the clipping path in device coordinates. This means that the initial full-page contents are now converted to device coordinates before putting them in the graphics state, and that no mapping is performed when applied the clipping to the painter. |

SerenityOS
Graphical Unix-like operating system for x86-64 computers.
About
SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.
Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.
You can watch videos of the system being developed on YouTube:

Features
- Modern x86 64-bit kernel with pre-emptive multi-threading
- Browser with JavaScript, WebAssembly, and more (check the spec compliance for JS, CSS, and WASM)
- Security features (hardware protections, limited userland capabilities, W^X memory,
pledge
&unveil
, (K)ASLR, OOM-resistance, web-content isolation, state-of-the-art TLS algorithms, ...) - System services (WindowServer, LoginServer, AudioServer, WebServer, RequestServer, CrashServer, ...) and modern IPC
- Good POSIX compatibility (LibC, Shell, syscalls, signals, pseudoterminals, filesystem notifications, standard Unix utilities, ...)
- POSIX-like virtual file systems (/proc, /dev, /sys, /tmp, ...) and ext2 file system
- Network stack and applications with support for IPv4, TCP, UDP; DNS, HTTP, Gemini, IMAP, NTP
- Profiling, debugging and other development tools (Kernel-supported profiling, detailed program analysis with software emulation in UserspaceEmulator, CrashReporter, interactive GUI playground, HexEditor, HackStudio IDE for C++ and more)
- Libraries for everything from cryptography to OpenGL, audio, JavaScript, GUI, playing chess, ...
- Support for many common and uncommon file formats (PNG, JPEG, GIF, MP3, WAV, FLAC, ZIP, TAR, PDF, QOI, Gemini, ...)
- Unified style and design philosophy, flexible theming system, custom (bitmap and vector) fonts
- Games (Solitaire, Minesweeper, 2048, chess, Conway's Game of Life, ...) and demos (CatDog, Starfield, Eyes, mandelbrot set, WidgetGallery, ...)
- Every-day GUI programs and utilities (Spreadsheet with JavaScript, TextEditor, Terminal, PixelPaint, various multimedia viewers and players, Mail, Assistant, Calculator, ...)
... and all of the above are right in this repository, no extra dependencies, built from-scratch by us :^)
Additionally, there are over two hundred ports of popular open-source software, including games, compilers, Unix tools, multimedia apps and more.
How do I read the documentation?
Man pages are available online at man.serenityos.org. These pages are generated from the Markdown source files in Base/usr/share/man
and updated automatically.
When running SerenityOS you can use man
for the terminal interface, or help
for the GUI.
Code-related documentation can be found in the documentation folder.
How do I build and run this?
See the SerenityOS build instructions. Serenity runs on Linux, macOS (aarch64 might be a challenge), Windows (with WSL2) and many other *Nixes with hardware or software virtualization.
