Timothy Flynn	f3146d3320	LibGfx: Implement a UTF-16 Color stringifier	2025-07-28 12:25:11 +02:00
Arran Ireland	9a8599f265	LibGfx+LibMedia+LibWeb: Use new Matrix subscript operator	2025-07-28 09:15:23 +02:00
Arran Ireland	423e944a92	LibGfx+LibWeb: Upgrade to multi-arg subscript operator in Matrix ... See the following for more details: https://en.cppreference.com/w/cpp/language/operators.html#Array_subscript_operator	2025-07-28 09:15:23 +02:00
Rocco Corsi	d322c3a21f	LibGfx: VulkanContext coverity reports integer_overflow on index ... Coverity static analysis reports that the code that scans the queue families for one that has the graphics bit, can be -1 if none are found, which could cause a problem when the -1 (signed) value is used later as an index in a uint32_t (unsigned) variable. Its not immediately clear how often this could occur, not finding a queue family with the graphics bit, but adding some protecting just in case.	2025-07-27 23:38:49 -04:00
Timothy Flynn	0e9b694058	LibGfx: Support UTF-16 text shaping ... We can achieve this with templating the string view type, and then just piping the view into the correct `hb_buffer_add_utf*` API.	2025-07-25 18:16:22 +02:00
Jelle Raaijmakers	a9862d60bf	LibGfx: Add Color::from_utf16_string()	2025-07-24 07:18:25 -04:00
Kenneth Myhra	09f336bf8f	LibGfx: Use static_cast instead of C-style cast	2025-07-20 12:30:43 +12:00
Jelle Raaijmakers	0f642ecb5c	LibGfx: Replace Bitmap::visually_equals() with ::diff() ... This produces more granural information on the actual pixel errors present between two bitmaps. It now also asserts that both bitmaps are the same size, since we should never compare two differently sized bitmaps anyway.	2025-07-17 12:59:11 +01:00
Jelle Raaijmakers	144eac44fb	LibGfx: Remove Font::pixel_size_rounded_up() ... The remaining callsites were removed in the previous commit.	2025-07-15 19:05:36 +01:00
Andreas Kling	a4fb21308d	LibWeb: Don't add range data for FontCascadeList with no Unicode ranges ... This fixes a bunch of WPT crashes in /html/canvas/offscreen/text/	2025-07-15 10:06:10 +02:00
Andreas Kling	0fece0650e	LibGfx: Let FontCascadeList quickly reject out-of-range code points ... By keeping track of the enclosing range around all Unicode ranges of a FontCascadeList entry, we can quickly reject any code point that's outside all ranges. This knocks font_for_code_point() from 7% to 3% in the profile when scrolling on https://screenshotone.com/	2025-07-14 19:05:25 +02:00
Lucien Fiorini	635adc8aa7	LibWeb/SVG: Implement resolution for a subset of SVG filters	2025-07-09 18:07:12 +01:00
Aliaksandr Kalenik	c18314b942	LibWeb+LibGfx: Replace BackingStore with PaintingSurface ... Now, when Skia backend context is available by the time backing stores are allocated, there is no need to have a separate BackingStore class. This allows us to get rid of BackingStore -> PaintingSurface cache.	2025-07-04 16:12:47 +02:00
ayeteadoe	d897bfae91	CMake: Rename all_generated target to better convey intent	2025-07-03 23:19:41 +02:00
ayeteadoe	25f5936dee	CMake: Rename serenity_* helper functions/macros to ladybird_*	2025-07-03 23:19:41 +02:00
Timothy Flynn	62d9a84b8d	AK+Everywhere: Replace custom number parsers with fast_float ... Our floating point number parser was based on the fast_float library: https://github.com/fastfloat/fast_float However, our implementation only supports 8-bit characters. To support UTF-16, we will need to be able to convert char16_t-based strings to numbers as well. This works out-of-the-box with fast_float. We can also use fast_float for integer parsing.	2025-07-03 09:51:56 -04:00
Jelle Raaijmakers	180bb0fc5d	Everywhere: Remove LibRIFF	2025-07-02 12:01:12 +01:00
ayeteadoe	2119ea982e	LibGfx: Enable in Windows CI	2025-06-26 19:35:14 -06:00
Jelle Raaijmakers	2687246808	LibGfx: Use NonnullRefPtr<Bitmap> for frame descriptors ... This makes it a bit easier to reason about where bitmaps should be available.	2025-06-25 22:54:48 +12:00
Tim Ledbetter	e69d9fb331	LibGfx: Destroy FontConfig string iterator after use ... This avoids a memory leak in `FontDatabase::font_directories()`.	2025-06-25 08:59:49 +02:00
Sam Atkins	423cdd447d	LibWeb+LibGfx: Apply editorial punctuation/whitespace/markup fixes ... Corresponds to d426109ea1 and fd08f81d06	2025-06-25 03:12:19 +12:00
Tom Lynch	b3d459f4de	LibGfx: Nearest neighbor scaling for ScalingMode::SmoothPixels	2025-06-23 16:05:52 +02:00
Luke Wilde	ffae0d8b2d	LibGfx/AVIF: Always reduce decoding output to a bit depth of 8 ... Gfx::Bitmap only supports a bit depth of 8, therefore we refused to load AVIF images which didn't have this bit depth. However, we can tell the libavif decoder to reduce the output depth by setting avifRGBImage.depth to 8. This allows us to support any input depth. Makes images load on https://www.ikea.com/ which uses Cloudflare Images to re-encode their images to 16-bit AVIF.	2025-06-18 14:27:24 +02:00
Colin Reeder	d4a5d16d27	LibGfx: Explicitly link against fontconfig	2025-06-17 16:55:50 -06:00
Shannon Booth	766cbf4937	LibGfx: Remove dependency on LibURL ... This was previously a dependency (from ICC, if I recall correctly), but this no longer appears to be the case.	2025-06-17 20:54:03 +02:00
Jelle Raaijmakers	46a46a1c61	LibGfx+LibWeb: Append glyphs in LineBoxFragment run more efficiently ... Since we know the number of glyphs we're going to append, ensure the LineBoxFragment run's capacity once and perform unchecked appends.	2025-06-17 17:03:33 +02:00
Jelle Raaijmakers	5ac067c804	LibGfx: Inline Font::pixel_metrics() ... Calls to this method were showing up in profiles.	2025-06-17 17:03:33 +02:00
Jelle Raaijmakers	df20ac0f3c	LibGfx: Optimize Gfx::measure_text_width() ... Instead of constructing a GlyphRun, just add the X advances of all glyphs to determine a text's width.	2025-06-17 17:03:33 +02:00
Jelle Raaijmakers	631c857301	LibGfx: Only determine glyphs info once in TextLayout ... We were calling into `hb_buffer_get_glyph_infos()` twice and setting up an unused `Vector<hb_glyph_info_t>`.	2025-06-17 17:03:33 +02:00
Jelle Raaijmakers	e80914a399	LibGfx: Use Vector::extend() to extend fonts in FontCascadeList ... This only grows the capacity once, if required.	2025-06-17 17:03:33 +02:00
Jelle Raaijmakers	7d1ee3a2fa	LibGfx+LibWeb: Perform unchecked appends related to text layout ... Use unchecked appends in places where we know for certain the vector has enough capacity.	2025-06-17 11:55:28 +02:00
Jelle Raaijmakers	6710aa102a	LibGfx: Return NonnullRefPtr in Gfx::shape_text() ... We always return a glyph run here.	2025-06-17 11:55:28 +02:00
Viktor Szépe	19f88f96dc	Everywhere: Fix typos - act III	2025-06-16 14:20:48 +01:00
aplefull	bfc79a403d	LibGfx: Fix ICC v2 profiles with table-based L* curves ... Skia's SkColorSpace::Make() doesn't seem to like ICC v2 profiles containing table-based L* transfer curves. Now we use skcms_ApproximateCurve() to convert these tables to parametric curves that Skia supports in case Skia's SkColorSpace::Make() fails.	2025-06-16 11:31:42 +02:00
Jelle Raaijmakers	dd4d7d0939	LibGfx: Ensure capacity for glyph runs in TextLayout ... We can reserve the capacity for new glyph runs since we already know the glyph count.	2025-06-13 17:31:18 +02:00
Jelle Raaijmakers	4b6489917b	LibGfx: Disable tech(variations) font support for now ... We apparently don't support it in the right way, since it causes the wrong font to display on https://ladybird.org.	2025-06-12 11:04:37 +01:00
Andrew Kaster	a267743095	LibGfx: Avoid importing FilterImpl into swift ... This header uses skia directly, and is not needed in swift.	2025-06-11 11:54:52 -06:00
Timothy Flynn	18718e0876	Meta: Sort all python imports	2025-06-09 11:25:14 -04:00
Timothy Flynn	34e178d0e7	LibGfx: Convert single quote string to double quotes ... Caught via ruff. Not sure why black didn't catch this one previously.	2025-06-09 11:25:14 -04:00
Sam Atkins	5a1c73d7e2	LibGfx+LibWeb: Update definitions of supported font formats and features ... Based very scientifically on what's listed here: https://harfbuzz.github.io/what-does-harfbuzz-do.html I've moved the code into LibGfx because including a HarfBuzz header directly from LibWeb is a little unpleasant. But the Gfx::FontTech enum follows the CSS definitions for font features for simplicity. TrueType collections are supported. SVG and Embedded OpenType are not, but they're not widely supported by other browsers so that's fine. Most of the features are completely supported by HarfBuzz, so we can just return true. Graphite support is optional (and it appears we use a build of HarfBuzz without it) but there's a define we can check. Incremental Font Transfer is a whole separate thing that we definitely don't support yet.	2025-06-05 12:10:29 +01:00
Lucien Fiorini	0fcb574041	LibGfx+LibWeb: Turn Gfx::Filter into a SkImageFilter wrapper	2025-06-01 23:22:10 +02:00
Andrew Kaster	6f9e56870e	CMake: Exclude GlobalFontConfig.h from autogenerated clang module ... This header file is never included by any other headers, and including it would require adding the fontconfig include paths to the swift interop header generation, which is not desirable.	2025-05-30 15:21:17 -06:00
Andrew Kaster	17b7f192c4	LibGfx: Add a strict CMake check for the libpng apng patch	2025-05-30 15:21:07 -06:00
blukai	3ab50be36a	LibGfx: Improve logical separation of font_directories' ifdefs ... in addition to what was proposed in https://github.com/LadybirdBrowser/ladybird/pull/4830#discussion_r2101301978	2025-05-26 12:14:29 -06:00
blukai	e356a4bd01	LibGfx: Rely on fontconfig(if enabled) for font directory resolution ... this commit also introduces GlobalFontConfig class that is now responsible for fontconfig initialization. it seems sane, even thought FcInit's docs state that if the default configuration has already been loaded, this routine does nothing.	2025-05-26 12:14:29 -06:00
blukai	4b3691ff39	LibCore+LibGfx: Move font_directories from LibCore to LibGfx ... the goal is to rely on fontconfig for font directory resolution. it doesn't seem like it would be appropritate to call to fontconfig funcs from within the LibCore. i'm not 100% confident that FontDatabase is the correct place.. seems okay?	2025-05-26 12:14:29 -06:00
blukai	6e00a38099	LibGfx: Enable otf fonts	2025-05-26 12:14:29 -06:00
Timothy Flynn	2f9957c618	Everywhere: Format all python files with black	2025-05-22 16:21:42 +02:00
Timothy Flynn	7280ed6312	Meta: Enforce newlines around namespaces ... This has come up several times during code review, so let's just enforce it using a new clang-format 20 option.	2025-05-14 02:01:59 -06:00
aplefull	7da2339c89	LibGfx: Properly skip IDAT chunks without fcTL in APNG files ... In the previous fix, we were still drawing IDAT data to the reference frame even when no fcTL was present. This would cause rendering issues when subsequent frames use APNG_BLEND_OP_OVER blending mode, as they would composite over the incorrect reference frame. This commit adds a simple check to properly skip any frame without an fcTL chunk.	2025-05-09 21:45:29 +02:00
