Simon Hausmann	9a4924fbbb	wgpu: Added support for wgpu 27 with Skia ... cc #9605	2025-10-06 19:10:31 +02:00
Ashley	a3a3844cef	feature/fontique - switch femtovg over and use a default fontdb for usvg (#9426) ... * Use default fontdb for usvg * Start adapting femtovg * Use DesignFontMetrics from sharedfontique * Restore fallback fonts * [autofix.ci] apply automated fixes * Add allow(dead_code) tag * [autofix.ci] apply automated fixes * Tiny comment change --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>	2025-09-24 16:54:09 +02:00
Simon Hausmann	0bb29cb5c2	wgpu: Improve backend avoidance ... - For Skia, also opt out of the WGPU GL backend - we're not attempting to map it to Skia. - For FemtoVG, avoid GL as well, because it produces artefacts.	2025-08-22 17:26:21 +02:00
Simon Hausmann	4f7bc76f1b	skia-wgpu: Avoid the vulkan backend on Windows ... ... as we don't enable the Vulkan feature by default with skia on Windows, because it's not in the binaries and thus would force everyone to build skia (which is a PITA on Windows).	2025-08-22 17:26:21 +02:00
Simon Hausmann	fd28676ab6	wgpu: Fall back to software rendering if there are no GPU-backed WGPU adapters ... Fixes #9164	2025-08-19 14:57:21 +02:00
Simon Hausmann	8ed0fd327e	wgpu: Switch to WGPU 26	2025-08-05 17:27:00 +02:00
Simon Hausmann	351324ae29	wgpu: Centralize setup ... By moving the adapter/device/etc. selection code into the wgpu_25 module, the setup code can be shared between FemtoVG and Skia (in the near future).	2025-08-03 13:23:47 +02:00
Tasuku Suzuki	3d7f616dee	Add conic gradient support for all backends (#9021) ... - Implement @conic-gradient(color angle, ...) syntax - Center is always at rectangle center (no center_x/center_y parameters) - 0 degrees starts at north (12 o'clock position) - Support Slint angle units: deg, rad, turn - Software renderer: Full native implementation - Qt backend: Native support with angle offset correction - Skia backend: Native support with angle offset correction - FemtoVG backend: Fallback to solid color (first gradient stop) ChangeLog: Added support for `@conic-gradient` Fixes #3957	2025-08-02 09:14:33 +02:00
Simon Hausmann	3101104f5c	Switch from WGPU 24 to WGPU 25 ... - Use a version of FemtoVG that uses WGPU 25 - Rename the unstable-wgpu-24 feature and wgpu_24 module - Fetch bevy from a revision on master branch that switches to WGPU 25 - Move the bevy example out of the common workspace: That way users of the repo don't get bevy pulled from git, unless they want to build the bevy example.	2025-07-09 11:30:05 +02:00
Olivier Goffart	01e6177d08	Reduce the size/alignment of Image ... Use u32 for the timestamp store as the cache key, this is enough precision so that there is no practical risk of ducplicates And remove the Path from no_std as this is not used in this version	2025-06-26 18:45:37 +02:00
Simon Hausmann	2725766772	WGPU: Make WGPU24 variant of GraphicsAPI non-exhaustive ... This way we can add the surface texture in a future release without breaking compatibility.	2025-06-13 17:04:17 +02:00
Olivier Goffart	8db7db9571	core: Revert the change to use "C-unwind" calling convention ... This broke the build on zephyr ``` /usr/bin/ld: /home/runner/work/slint/slint/build/zephyr/NSI/home/runner/work/slint/slint/build/zephyr/zephyr.elf.loc_cpusw.o:(.data.DW.ref.rust_eh_personality[DW.ref.rust_eh_personality]+0x0): undefined reference to `rust_eh_personality' ```	2025-06-12 15:29:23 +02:00
Simon Hausmann	2d6ebc7df7	Move TryFrom::try_from<wgpu::Texture> for Image into the wgpu_24 module	2025-06-12 14:24:58 +02:00
Simon Hausmann	5d40fa167e	WGPU: Add missing derive_more::Error derivation for wgpu24::TextureImportError ... cc #8631	2025-06-12 14:24:58 +02:00
Simon Hausmann	7af9eec820	wgpu: Export the error type for TryFrom<wgpu::Texture> for Image as slint::wgpu_24::WGPUTextureImportError ... cc #8631	2025-06-12 14:24:58 +02:00
Olivier Goffart	af573e6401	vtable: Don't automatically add extern C	2025-06-06 14:47:46 +02:00
Olivier Goffart	f91b61c8ee	corelib: Remove the extern call in the vtable for wasm ... In fact, remove it for non-C++ Because wasm doesn't support C-unwind. And actually warns about incompatible ABI for the rest Fixes #8449	2025-06-06 14:47:46 +02:00
Olivier Goffart	23962b3e25	Upgrade cbindgen and use unsafe(no_mangle) attributes (#8539) ... To be compatible with the 2024 edition, we need to wrap the `no_mangle` attribute in `unsafe()`. The parsing for that in cbindgen was only added in the version 0.28, but we couldn't upgrade cbindgen before because of a regression in cbindgen 0.27 that prevented us from upgrading. Now that cbindgen 0.29 is released with a fix, we can prepare for the 2024 edition	2025-05-26 11:21:33 +02:00
Simon Hausmann	35c972c227	Add example of rendering a Bevy scene into Slint (#8380)	2025-05-19 15:25:40 +02:00
Simon Hausmann	2f2478d1ea	WGPU: Clean up public API ... - Create a `slint::wgpu_24` module - Re-export `wgpu` in it - Place the WGPU config types used by the `BackendSelector::require_wgpu_24` function in it, and remove the 24 infix. As an upside, this also adds the feature guard to the docs at least for the `wgpu_24` module.	2025-04-30 15:54:06 +02:00
Simon Hausmann	da5e7d5b22	WGPU: Add support for using WGPU textures in Slint ... This adds a `unstable-wgpu-24` feature that exposes WGPU types in the GraphicsAPI enum, adds `require_wgpu_24()` to the backend selector, and adds a conversion from `wgpu::Texture` to `slint::Image`. The `require_wgpu_24()` function in the selector will be extended in the future (before the next release) to permit specifying additional aspects of the WGPU configuration.

Nigel Breslaw	7c0b212a6a	fix: to-hsv() should not return a negative hue value (#8077) ... Internally a hue could be in negative degrees. The resulting color was fine, however using to-hsv() would then expose this negative value. This ensure the internal value is positive. Some tweaks were needed to help tests pass but a real fix would be proper color comparisons. Floating point issues turn up when converting from hex to floats.	2025-04-09 10:58:07 +03:00
Nigel Breslaw	ffce61ca97	HSV should wrap hue values otherwise it outputs an invalid hue of black (#8024) ... Fix by wrapping around at 360. Added tests. Updated the docs.	2025-04-03 12:33:40 +03:00
Olivier Goffart	09e2b18ea3	Fix documentation of image formats ... Shortly before 1.10, we dicided not to enable most format by default. But the documentation was not updated to reflect that Closes #6574	2025-03-25 12:27:39 +01:00
Simon Hausmann	df6c99871d	Change TargetPixelBuffer's draw_texture function to take a data structure instead of many arguments	2025-02-24 17:02:10 +01:00
Yuri Astrakhan	2567880db8	Fix clippy::empty_line_after_doc_comments	2025-02-08 11:39:18 +01:00
Yuri Astrakhan	05f4fc0cde	Auto-fixed clippy::needless_return ... `__CARGO_FIX_YOLO=1` is a hack, but it does help a lot with the tedious fixes where the result is fairly clear. See https://rust-lang.github.io/rust-clippy/master/index.html#needless_return ``` __CARGO_FIX_YOLO=1 cargo clippy --fix --all-targets --workspace --exclude gstreamer-player --exclude i-slint-backend-linuxkms --exclude uefi-demo --exclude ffmpeg -- -A clippy::all -W clippy::needless_return cargo fmt --all ```	2025-02-07 09:46:49 +01:00
Yuri Astrakhan	bcb2953f00	Auto-fixed clippy::unnecessary_map_or ... This is a hacky approach, but does help a lot with the tedious fixes. See https://rust-lang.github.io/rust-clippy/master/index.html#/unnecessary_map_or ``` __CARGO_FIX_YOLO=1 cargo clippy --fix --all-targets --workspace --exclude gstreamer-player --exclude i-slint-backend-linuxkms --exclude uefi-demo --exclude ffmpeg -- -A clippy::all -W clippy::unnecessary_map_or cargo fmt --all ```	2025-02-07 09:02:31 +01:00
Yuri Astrakhan	5356fdcf89	Fix clippy issues, plus a few manual cleanups ... * Run `cargo clippy --fix` * `BackendSelector` is easier to instantiate with auto `Default`	2025-02-06 17:28:51 +01:00
Yuri Astrakhan	61de4d56b0	Fix all format arg inlining ... Ran this command: ```shell cargo clippy --fix -- -A clippy::all -W clippy::uninlined_format_args ```	2025-02-06 10:16:20 +01:00
Olivier Goffart	c98d234b9e	Janitor: Always use `#![no_std] for runtime lib ... And call `extern crate std` when the feature is enabled. I've read this is the good practice on how to do it. So that the std prelude is no longer included automatically. There is then less difference between std and and no-std build which should avoid surprises in the CI when we use things from the prelude. The downside is that there is a bit of churn in the tests	2025-01-27 19:22:00 +01:00
Olivier Goffart	fbaa18aafc	Docs: Update docs for image ... Link to the API docs from the image type.	2025-01-15 08:03:00 +01:00
Simon Hausmann	2ec0522151	Fix panic in FemtoVG and Skia renderers with certain drop shadows ... If the effectively drop shadow size would be zero, the FemtoVG and Skia item renderers would panic. The following test-case reproduces this: ```slint export component Test inherits Window { Rectangle { drop-shadow-color: black; drop-shadow-offset-x: 1px; drop-shadow-blur: -0.5px; width: 0.5px; height: 0.5px; background: blue; } } ``` ChangeLog: [Renderers] Fix panic with FemtoVG and Skia renderers for certain drop shadows.	2025-01-06 12:40:44 +01:00
Olivier Goffart	4e7bbcf2ba	Try to improve rendering (positioning) of signed field distance font. (#6868) ... * WIP: swrenderer: use fixed point for the pixmap font coordinate * swrenderer: signed distance field: move the glyph to the middle * swrenderer: round the advance instead of truncating it in distance field * swrenderer: actually align the gplyph on the sub-pixel precision sub-pixel within the source. * swrenderer: adapt the threshold for signed distance field sqrt(2) is the distance to the diagonal, seems like this gives sharper fonts * Fix bug in the elision, and re-upload the screenshort the screenshot changed because the afvanced is now rounded intead of truncated	2024-11-30 23:03:31 +01:00
Simon Hausmann	a7a3b3f9ee	Changelog: C++: Add slint::Window::take_snapshot() ... Corresponds to the Rust API.	2024-11-13 12:38:36 +01:00
Simon Hausmann	a98d4709be	Move printer demo and energy-monitor into new top-level demos/ folder ... These are showing off use-cases for Slint, but they're not examples showing individual Slint features. Also removed the old printerdemo while at it.	2024-10-25 12:09:32 +02:00
Olivier Goffart	d8ab4e4600	Signed DistanceField font rendering in swrenderer ... Note that this is still disabled in the compiler with no way to enable it with public API	2024-10-23 09:12:30 +02:00
Simon Hausmann	0b028bfb6f	Add support for a font-metrics property to Text/TextInput. (#6452) ... The struct held provides access to the design metrics of the font scaled to the font pixel size used by the element. ChangeLog: Slint Language: Added font-metrics property to `Text` and `TextInput`. Closes #6047	2024-10-05 17:00:46 +02:00
Tobias Hunger	8c25d44a49	core: Fix some clippy warnings ... Just disable the clippy warning about unnecessary cast: All current occurances are due to Coord being an alias to f32 almost all the time and the cast is necessary when it is not.	2024-10-02 17:05:05 +02:00
Simon Hausmann	7db5024c52	Generate bindings of Image::to_rgb8/to_rgba8/to_rgba8_premultiplied f… (#6405) ... ChangeLog: [C++] Add `Image::to_rgb8/to_rgba8/to_rgba8_premultiplied` pixel buffer accessors. Fixes #6399	2024-10-01 10:55:11 +02:00
Simon Hausmann	386710cd6d	Fix repeated loading of an image by path if the file was changed since last time ... Fixes #6030	2024-09-04 17:19:42 +02:00
Simon Hausmann	882cbd1541	Add comment to make SharedImageBuffer non_exhaustive when it ever becomes public	2024-07-08 16:58:06 +02:00
Tobias Hunger	e74745c68a	backout of commit 402f7ea649 ... rgb crate has eben fixed upstream, remove the temporary work-around again.	2024-07-08 15:38:23 +02:00
Simon Hausmann	402f7ea649	Work around build breakage in rgb 0.8.42 ... See https://github.com/kornelski/rust-rgb/issues/116 for details cc #5574	2024-07-08 11:52:57 +02:00
Simon Hausmann	e35d05f6b9	API Review: Remove SharedImageBuffer from public API and rename Window::grab_window() to take_snapshot() ... Use SharedPixelBuffer as return value for take_snapshot() and provide counter-parts to from_rgb* in Image as to_rgb*	2024-07-05 20:46:55 +02:00
Tobias Hunger	f78ea5e7cf	janitor: Fix clippy "field assignment outside of initializer ... ... for an instance created with Default::default()"	2024-06-24 14:59:47 +02:00
Tobias Hunger	09e9cdebb1	janitor: Fix clippy "duplicated attribute"	2024-06-24 14:59:47 +02:00
Tobias Hunger	571ee7a0bb	janitor: Fix clippy "parameter is only used in recursion"	2024-06-24 14:59:47 +02:00
Olivier Goffart	c89ea56abb	Update a bunch of dependencies ... Bigger change is cause by resvg/usvg which now takes the font database in a Arc, so we must store it in a Arc ourself to cheaply lend it to usvg	2024-06-23 16:47:13 +02:00
Simon Hausmann	db3d726886	Make it possible to retrieve a SharedImageBuffer for a slint::Image in Rust ... This change exposes functionality of already existing internal API that all renderers use to obtain pixels for upload to the screen - so it's rather well tested. This also exposes the `SharedImageBuffer` API, an enum that represents different SharedPixelBuffer encodings.	2024-06-11 07:46:57 -07:00
