Andreas Kling	3873b1d8cf	LibWeb: Create XML document object for SVG-as-image ... It's not enough to just use the XML parser, we also have to make sure the DOM document we produce is an actual XML document. Fixes #5966	2025-08-23 14:01:37 +01:00
Tim Ledbetter	aadd563592	LibWeb: Replace usages of dynamic_cast with as and as_if	2025-08-22 20:26:09 +02:00
Andreas Kling	3c808de270	LibWeb: Use XML parser for SVG-as-image documents ... We were already using the XML parser for SVG files when opening at the top level. This patch makes things consistent by using the same code path when parsing SVG-as-image. We also make some tweaks in SVG presentation attribute handling since we can no longer rely on the HTML length attribute parsing quirk when parsing width/height attributes.	2025-08-22 11:35:59 +02:00

Tim Ledbetter	1d745884be	LibWeb: Parse the shape-rendering property	2025-08-19 09:47:28 +01:00
Tim Ledbetter	ad06ac0d58	LibWeb: Implement the color-interpolation property for SVG gradients ... This changes the operating color space for gradient `<linearGradient>` and `<radialGradient>` elements.	2025-08-17 10:51:05 +02:00
Timothy Flynn	70db474cf0	LibJS+LibWeb: Port interned bytecode strings to UTF-16 ... This was almost a no-op, except we intern JS exception messages. So the bulk of this patch is porting exception messages to UTF-16.	2025-08-14 10:27:08 +02:00
Andreas Kling	bd7599ccfc	LibCore: Remove macro-generated EventReceiver::try_create(...) factories ... We can just use the infallible factory everywhere instead.	2025-08-11 16:55:25 +02:00
Tim Ledbetter	b15c4cccbf	LibWeb: Ignore non-element nodes when evaluating filters ... This prevents an unknown filter debug message would be printed for comments.	2025-08-08 23:54:17 +01:00
Sam Atkins	4e92ab52e3	LibWeb/CSS: Rename CSSKeywordValue -> KeywordStyleValue ... The typed-om CSSKeywordValue will need to be a separate class.	2025-08-08 15:19:03 +01:00
Sam Atkins	c57975c9fd	LibWeb: Move and rename CSSStyleValue to StyleValues/StyleValue.{h,cpp} ... This reverts 0e3487b9ab. Back when I made that change, I thought we could make our StyleValue classes match the typed-om definitions directly. However, they have different requirements. Typed-om types need to be mutable and GCed, whereas StyleValues are immutable and ideally wouldn't require a JS VM. While I was already making such a cataclysmic change, I've moved it into the StyleValues directory, because it *not* being there has bothered me for a long time. 😅	2025-08-08 15:19:03 +01:00
Andreas Kling	34ec33d71c	LibWeb: Don't treat SVG "use clone" removals as "use source" removals ... We were failing to discriminate between DOM removals happening to SVG elements cloned as part of an SVG use element instantiation. When a "use source" element is removed, all clones of that source must be updated to reflect the change. But when a "use clone" element is removed, that's fine. This was causing the surprising disappearance of use element subtrees, seen for example on https://cal.com/	2025-08-07 22:15:36 +02:00
Andreas Kling	42802b0785	LibWeb: SVG use element shadow roots should be closed, not open ... This goes against the spec but matches all other browser engines.	2025-08-07 22:15:36 +02:00
Jelle Raaijmakers	85ad99b98a	LibWeb: Implement <feMerge> SVG filter	2025-08-07 16:41:12 +02:00

Jelle Raaijmakers	7162c73b6c	LibWeb: Add SVGUnitTypes ... The empty `.h` is required since our generated bindings currently always try to include one.	2025-08-06 23:05:56 -04:00
Jelle Raaijmakers	cd1cf75f7b	LibWeb: Unbreak SVGFilterElement compilation ... This was caused by an undetected merge conflict.	2025-08-06 15:47:44 +02:00
Tim Ledbetter	1dd3608960	LibWeb/SVG: Apply SVGFeBlendElement blend mode ... Previously, the blend mode was always assumed to be `normal`.	2025-08-06 15:21:03 +02:00
Jelle Raaijmakers	3d613a2ac4	LibWeb: Simplify SVGFilterElement::gfx_filter() ... No functional changes.	2025-08-06 14:00:31 +01:00
Jelle Raaijmakers	400a36aac1	LibWeb: Warn about unknown SVG filters ... This might give some debug noise, but it's better than remaining silent.	2025-08-06 14:00:31 +01:00
Timothy Flynn	04d32deb52	LibWeb: Port SVGFormattingContext to UTF-16	2025-08-05 15:13:36 +02:00

Callum Law	344d6199da	LibWeb: Use correct colors for SVGFEFloodElement::flood_color ... Previously we would always render floods as black, we now use the computed color. We also now support relative lengths within any `calc`s present.	2025-08-04 11:29:05 +01:00
Callum Law	3b52b1139a	LibWeb: Support relative lengths in stop-color calcs	2025-08-04 11:29:05 +01:00
Idan Horowitz	bb6855c849	LibWeb: Add a getter for the default image bitmap of SVGImageElement ... The default image bitmap is the first frame for animated bitmaps, and the only frame for non-animated bitmaps.	2025-08-03 21:47:48 +02:00
Timothy Flynn	50fed1d65c	LibWeb+LibWebView+WebContent+UI: Port the document title to UTF-16	2025-08-02 10:10:14 -07:00
Aliaksandr Kalenik	61114f6d16	LibWeb: Rename PaintContext to DisplayListRecordingContext ... PaintContext dates back to a time when display lists didn't exist and it truly represented "paint context". Renaming it to better align with its current role.	2025-08-01 05:25:56 -04:00
Tete17	223b1cc704	LibWeb: Add barebones SVGAnimationElement class ... Many wpt test on trusted-types relay on this class being defined to even begin the test as it declares some event handlers. This is not really an implementation but the most basic setup needed to run the tests.	2025-07-30 15:51:35 +01:00
Andreas Kling	77abe2a84d	LibWeb: Allow ImageProvider subclasses to visit additional GC edges ... More prep work for CSS content:image.	2025-07-28 22:46:27 +02:00
Andreas Kling	0e94c4e270	LibWeb: Allow ImageProvider to not have a corresponding DOM node ... This is prep work for CSS content:image.	2025-07-28 22:46:27 +02:00
Timothy Flynn	5c561c1a53	LibWeb: Port node text content to UTF-16	2025-07-28 18:30:50 +02:00
Aliaksandr Kalenik	8569124b87	LibWeb: Fix scroll state refresh in cached display list for iframes ... 6507d23 introduced a bug when snapshot for iframe is saved in `PaintNestedDisplayList` and, since display lists are immutable, it's not possible to update before the next repaint. This change fixes the issue by moving `ScrollStateSnapshot` for nested display lists from `PaintNestedDisplayList` to `HashMap<NonnullRefPtr<DisplayList>, ScrollStateSnapshot>` that is placed into pending rendering task, making it possible to update snapshots for all display lists before the next repaint. This change doesn't have a test because it's really hard to make a ref test that will specifically check scenario when scroll offset of an iframe is advanced after display list is cached. We already have `Tests/LibWeb/Ref/input/scroll-iframe.html` but unfortunately it did not catch this bug. Fixes https://github.com/LadybirdBrowser/ladybird/issues/5486	2025-07-26 11:53:21 -04:00
Tim Ledbetter	d38fac7518	LibWeb/SVG: Ignore view boxes with negative width or height	2025-07-22 00:52:24 +02:00
Tim Ledbetter	a990de65e4	LibWeb: Implement SVGViewElement ... This identifies a particular region of an SVG image, which can then be linked to by an SVG fragment identifier.	2025-07-22 00:52:24 +02:00
Tim Ledbetter	1263d58689	LibWeb: Ignore zero width when calculating SVG intrinsic aspect ratio ... Previously, an SVG with width of zero would have am intrinsic aspect ratio of zero. With this change, if an SVG has a width or height of zero, the intrinsic aspect ratio is determined by the SVG's viewbox.	2025-07-21 11:29:25 +02:00
Timothy Flynn	9582895759	AK+LibJS+LibWeb+LibRegex: Replace AK::Utf16Data with AK::Utf16String	2025-07-18 12:45:38 -04:00
Timothy Flynn	a43cb15e81	LibJS+LibWeb: Replace JS::Utf16String with AK::Utf16String	2025-07-18 12:45:38 -04:00
Sam Atkins	8538186ca5	LibWeb/SVG: Add serialization of Paths ... CSS users (like the `path()` function) need to be able to serialize their path data in a canonical form.	2025-07-17 13:59:23 -04:00
Sam Atkins	6b53454b68	LibWeb/SVG: Move path data into Path.{h,cpp} ... More things need this than just the `<path>` element, so let's avoid having to include `SVGPathElement.h` in places that don't need it. Minor changes at the same time: - Wrap it in a Path class - Specify underlying type for PathInstructionType - Make a couple of free functions into methods - Give PathInstruction an operator== No functionality changes.	2025-07-17 13:59:23 -04:00
Tim Ledbetter	4dd538e708	LibWeb/SVG: Prefer href to xlink:href attribute on images	2025-07-12 13:13:47 +02:00
Tim Ledbetter	93a35895ae	LibWeb/SVG: Don't crash when changing SVG image href ... Previously, a segfault could occur if `m_resource_request` was replaced before its callbacks were invoked.	2025-07-12 13:13:47 +02:00

Jelle Raaijmakers	ffcf91cd30	LibWeb: Correct initialization order for SVGFE*Element ... We should first set the prototype before initializing our base, otherwise e.g. attributes will simply not work.	2025-07-11 11:25:59 +01:00
