The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Breaking Changes

• Window::set_inner_size has been replaced with Window::request_inner_size. This function now matches winit's underlying request_inner_size behavior. The function returns an option containing the new size if the size was able to be applied before the function returns.

  This new function properly updates the inner_size and outer_size when the underlying window is resized immediately. Notably, this happens on Wayland but may happen on some other platforms as well.

  Users who are using Kludgine directly should invoke Kludgine::resize to apply the new size.

• Window::winit now returns an Arc-wrapped winit Window.

• WindowBehavior::render no longer returns a bool. Closing the window can be done through the RunningWindow parameter.

• DrawableExt::scale now accepts a parameter that can be an f32, (f32, f32), or Point<f32>. This change allows independent scaling of the x and y axis.

• Text has made its fields private.

Added

• StrokeOptions::upx_wide returns stroke options for a given unsigned pixel stroke width.

• LazyTexture, CollectedTexture, AnyTexture, TextureCollection, and Texture now implement PartialEq.

• PendingApp::on_unrecoverable_error is a new function that allows applications to take control when an unrecoverable error occurs. Previously, these errors would panic, and the provided implementation is a panic.

• App::execute executes a closure on the main event loop thread.

• Shape has several new functions to create textured shapes:

  • Shape::textured_round_rect
  • Shape::textured_rect
  • Shape::textured_circle

• Renderer::draw is a new function that allows attaching arbitrary drawing operations to a Drawing. The drawing calls will be clipped to the current clipping rectangle.

• Kludgine::texture_format and Kludgine::multisample_state are new functions that return the configuration specified when Kludgine was initialized.

• RenderingGraphics::pass() and RenderingGraphics::pass_mut() give access to the underlying render pass.

• Text::align allows specifying a cosmic_text::Align setting and a width to perform the alignment within.

Fixed

• Plotters integration now strokes paths offsetting by half of the stroke width to ensure proper subpixel alignment.
• Plotters integration text drawing now honors anchor positioning, rotation, and properly sets the line height based.

v0.11.0 (2024-09-14)

Breaking Changes

• App is a new type that replaces the previous type alias pointing to appit::App. The previously exported type wasn't able to be used beyond passing it as a parameter for opening additional windows. This new type exposes additional winit information including monitor configurations.
• Window::ocluded has had its spelling fixed and is now Window::occluded.
• Window::position has been renamed to Window::outer_position
• Window::set_position has been renamed to Window::set_outer_position.

Fixed

• Window now calls winit's pre_present_notify() before presenting the surface.
• WindowHandle's Clone implementation no longer requires its generic parameter to implement Clone.
• Temporarily worked around a Wayland-only issue where window resize events are not being generated from explicit window sizing requests.

Added

• PendingApp::on_startup executes a callback once the event loop has begun executing.
• Monitors, Monitor, and VideoMode are new types that offer information about the monitor configurations available to the application. This information can be retrieved from an App or ExecutingApp.
• WindowBehavior::moved is invoked when the window is repositioned.
• Window::outer_size is a new function that returns the window's size including decorations.
• Window::inner_position returns the position of the top-left of the content area of the window.
• App::prevent_shutdown() returns a guard that prevents the application from closing automatically when the final window is closed.
• WindowBehavior::initialized is invoked once the window has been fully initialized.
• WindowBehavior::pre_initialize is invoked before wgpu is initialized on the window.

v0.10.0 (2024-08-20)

Breaking Changes

• Added Zoom setting to [Kludgine], allowing a second scaling factor to be applied to all scaled operations. This change has affected these APIs:

  • [Kludgine::resize()]: Now takes an additional parameter zoom.
  • [Kludgine::scale()]: Now returns an effective scale combining zoom and DPI scaling.
  • [Kludgine::dpi_scale()]: A new function returning the currently set DPI scale.
  • [Kludgine::zoom()]: A new function returning the current zoom value.
  • [Kludgine::set_zoom()]: A new function setting just the zoom value.
  • [Kludgine::set_dpi_scale()]: A new function setting just the DPI scale.
  • [`Graphics::set_zoom()]: A new function setting the zoom level for a graphics context.

Added

• CornerRadii now implements figures::Round.

v0.9.0 (2024-07-22)

Breaking Changes

• wgpu has been updated to 22.0.0.
• cosmic-text has been updated to 0.12.0.

Added

• WindowBehavior::memory_hints is a new trait function that controls the memory hints wgpu is initialized with. The provided implementation returns wgpu::MemoryHints::default().

v0.8.0 (2024-05-12)

Breaking Changes

• Frame::render_into no longer takes a Graphics parameter, but instead accepts the wgpu::Queue and wgpu::Device parameters directly. Using Graphics causes lifetime issues in some rendering workflows.

• The render module has been renamed to drawing to match the type it contains. The old name was a remnant from when Drawing used to be named Rendering, which was incredibly confusing with Renderer types around as well.

• This crate now supports wgpu 0.20.0.

• This crate now supports cosmic-text 0.11.2.

• This crate now supports image 0.25.1.

• These WindowBehavior functions have had a &Self::Context parameter added to them, ensuring each function where Kludgine is requesting information from the implementor either receives an &self or an &Self::Context:

  • WindowBehavior::power_preference()
  • WindowBehavior::limits()
  • WindowBehavior::multisample_count()

• SpriteSheet::new() now takes an additional parameter: gutter_size. Passing Size::ZERO will cause the returned sprite sheet to be the same as before this change.

  This new parameter allows using sprite sheets that have been exported with consistent spacing between each sprite.

• These APIs now require exclusive references to the application:

  • WindowBehavior::open
  • WindowBehavior::open_with

• These events have been renamed to match winit's nomenclature:

  • WindowBehavior::touchpad_magnify -> WindowBehavior::pinch_gesture
  • WindowBehavior::smart_magnify -> WindowBehavior::double_tap_gesture

Changed

• All &Appplication bounds now are ?Sized, enabling &dyn Application parameters.
• Color now exposes its inner u32 as public.

Added

• WindowBeahvior::pan_gesture is a new event provided by winit.
• Kludgine::id() returns the instance's unique id.
• Kludgine::REQUIRED_FEATURES specifies the `wgpu::Features`` that Kludgine uses.
• Kludgine::adjust_limits() adjusts wgpu::Limits to ensure Kludgine will function.
• Texture::multisampled allows creating a Texture that can be used as a multisample render attachment.
• Texture::copy[_rect]_to_buffer are convenience helpers for copying image data to a wgpu::Buffer.
• Texture::wgpu() returns a handle to the underlying wgpu::Texture.
• Texture::view() returns a wgpu::TextureView for the entire texture.
• A new feature plotters enables integration with the excellent plotters crate. Renderer::as_plot_area() is a new function that returns a plotters::DrawingArea.
• Kludgine::rebuild_font_system() is a new function that recreates the cosmic_text::FontSystem, which has the net effect of clearing font-database related caches.
• WindowBehavior::present_mode() allows a window to pick a different presentation mode. The default implementation returns wgpu::PresentMode::AutoVsync.

Fixed

• Drawing::render() no longer makes any assumptions about the current clipping rectangle when drawing is started.
• Color correction for Srgb is now being done more accurately using the palette crate. This affects colors being applied to textures as tints and shape drawing, but the Srgb handling of textures themselves remain handled purely by wgpu.
• Drawing text with an empty first line no longer panics.

v0.7.0

Breaking Changes

• UnwindSafe has been removed from the bounds of WindowBehavior::Context, and various types may or may no longer implmement UnwindSafe. The underlying requirement for this has been removed from appit.
• Texture::lazy_from_data and Texture::lazy_from_image have been refactored into constructors of a new type: LazyTexture::from_data/LazyTexture::from_image.
• include_texture! now returns a LazyTexture instead of a Texture.
• SharedTexture::region() has been removed. TextureRegion::new() is the replacement API that allows creating a region for any ShareableTexture.
• Sprite::load_aseprite_json now accepts impl Into<ShareableTexture> instead of &SharedTexture. In theory, no code will break from this change due to trait implementations.
• SpriteSheet::texture is now a ShareableTexture.

Added

• app::PendingApp is a type that allows opening one or more windows before running an application.

• app::App is a handle to a running application.

• app::Window::app() returns a handle to the application of the window.

• WindowBehavior::open[_with]() are new functions that allow opening a window into a reference of an App or PendingApp.

• CanRenderTo::can_render_to() is a new trait that checks if a resource can be rendered in a given Kludgine instance.

  This is implemented by all types in Kludgine that utilize textures.

• LazyTexture is a new texture type that supports being shared across different windows/wgpu rendering contexts by loading its data on-demand. LazyTexture::upgrade() loads a SharedTexture that is compatible with the given graphics context.

• ShareableTexture is a texture type that can resolve to a SharedTexture. Currently this is either a SharedTexture or a LazyTexture.

• RunningWindow::close is allows closing a window.

Fixed

• Internally, text drawing now uses weak references for the glyph handles to prevent wgpu resources from being freed if a MeasuredText was being held.
• Each window now has its own wgpu::Instance instead of sharing a single instance between windows.
• Each Window frame now waits until it's fully rendered before yielding back to the windqow loop.
• When a Window has a 0 dimension, it will no longer try to redraw. This presented as a panic when a window was minimized.
• Subpixel alignment of text rendering is no longer accounted for twice. Additionally, TextOrigin::Center rounds the offset calculated to the nearest whole pixel.
• A workaround has been added that caused clipping on the OpenGL backend to only use the final scissor rect.

v0.6.1 (2023-12-19)

Fixed

• A panic "Unsupported uniform datatype! 0x1405" has been resolved that occurred on some devices where push constants were being emulated and only signed integers were unspported.
• #66: A rounding error has been fixed when calculating the text width would cause the line width to be rounded down in some cases.
• If wgpu reports a SurfaceError::Lost, the create_surface() call is now correctly made on the main thread rather than the window thread. Thanks to @Plecra for reviewing the unsafe code and noticing this issue. This review also led to further reductions in the amount of unsafe code and improved the safety comments.

v0.6.0 (2023-12-18)

This version is a complete rewrite. While some code was copied across, this library now directly depends upon wgpu instead of using easygpu, and it has an API inspired by wgpu's Encapsulating Graphics Work article.

v0.5.0 (2023-04-28)

Breaking Changes

• set_always_on_top/with_always_on_top/always_top have been replaced with set_window_level/with_window_level/window_level respectively. This change was due to upgrading to the latest winit.
• The MSRV has been updated to 1.64.0 due to nested dependency requirements.
• These feature flags have been renamed:
  • serialization has become serde
  • tokio-rt has become tokio
  • smol-rt has become smol

Changes

• Updated easygpu to v0.5.0.
  • wgpu has been updated to v0.16.0
• winit has been updated to v0.28.3
• palette has been updated to v0.7.1

Fixes

• Returning a scale from Window::additional_scale now works.
• CloseResponse is now exported.

Added

• Scene::set_additional_scale has been added to set the scaling factor between Points and Scaled. This allows application-level scaling in addition to the DPI scaling Kludgine already does.

v0.4.0 (2023-01-27)

Changes

• Updated easygpu to 0.4.0:
  • wgpu has been updated to 0.15.0.

v0.3.1 (2022-11-06)

Changes

• Updated rusttype to 0.9.3:
  • ttf-parser has been updated to 0.15.2.
  • Versions of rusttype are now pinned to prevent transient dependency upgrades breaking compilation.

v0.3.0 (2022-11-06)

Changes

• Updated easygpu to 0.3.0:
  • wgpu has been updated to 0.14.0.
  • winit has been updated to 0.27.4.

v0.2.0 (2022-07-31)

Changes

• Updated easygpu to 0.2.0:
  • Updated wgpu to 0.13.1
  • Updated lyon_tessellation to 1.0.1

v0.1.0 (2022-02-02)

Changes

• Switching off of pre-release version numbering. They just add more pain than they're worth.
• Updated dependencies to wgpu 0.12

Fixes

• Fixed incompatibility with image crate update.
• Changed dependency versions to be less lenient.

v0.1.0-dev.6 (2021-12-07)

Fixes

• Fixed issue where render_one_frame would freeze in headless environments (#53).

v0.1.0-dev.5 (2021-12-06)

Changed

• Updated dependencies for compatability with wgpu 0.11.1.
• Implemented Sprite alpha rendering. The APIs already existed, but the alpha value was being ignored.

v0.1.0-dev.4 (2021-10-31)

Added

• Sprite::current_frame immutably retrieves the current frame. This is equivalent to calling Sprite::get_frame(None) but can be used in non-mutable settings.

v0.1.0-dev.3 (2021-10-11)

Changes

• Updated easygpu and easygpu-lyon, which moves Kludgine onto wgpu 0.11.

v0.1.0-dev.2 (2021-10-11)

Added

• WindowCreator and WindowBuilder now support initial_position.

Breaking Changes

• WindowCreator and WindowBuilder now use Points as the unit for initial_size. When creating the window, we now request the logical size rather than pixels, correspondingly.

Fixes

• Redrawing while resizing is done with more expediency. Previously, we were waiting for the OS to ask for us to redraw after resizing, rather than forcing a resize.

v0.1.0-dev.1 (2021-09-01)

Breaking Changes

• Added WindowHandle, which allows interacting with the window after it has been built. This parameter is passed into nearly all Window trait functions now.
• WindowCreator now takes &self parameter for all methods. There was no reason for these methods to be static, and it prevented a window from being able to control how it was built based on its initial configuration.

Fixes

• Rendering a SpriteSource using a Point without specifying a Size now renders it at Scaled resolution. This restores the behavior before the parameters were switched to Displayable.

v0.1.0-dev.0 (2021-08-22)

Breaking Changes

• Removed all user interface code, and spun off a new user interface project, Cushy.
• Split Kludgine into three crates:
  • kludgine-core: The rendering aspects of Kludgine. Can now be used for headless rendering as well.
  • kludgine-app: The windowing/event handling layer of Kludgine.
  • kludgine: An omnibus crate that marries the two with one crate include.
• Now uses figures for its math types. If you're using functionality that was in euclid but is no longer available in figures, please submit an issue. We may not add all requested functionality, but as long as it extends one of the types figures already has, it likely will be added upon request.
• Introduced unstable-apis feature flag. The plan for this flag is to offer a way to provide APIs that are still under heavy development to be used without forcing semver updates when the APIs change. After 1.0, breaking changes to unstable-apis will be one of the factors that causes minor version increments.
