* Validate width and height inputs
- Fixes#157
* Add window size check to `imgui-winit` demo
- There is really nothing better that can be done in this case.
- The surface, buffer, and world sizes must all be non-zero.
- A zero-length surface would (previously) panic in `wgpu`.
- A zero-length buffer would panic with the new assertions.
- A zero-length world would cause a divide-by-zero panic when drawing.
- Was originally resizing the pixel buffer with `PhysicalSize` units, which is definitely incorrect. (The pixel buffer is created with `LogicalSize` units.)
- Updated the World struct to retain its own size information.
- This issue can be seen when creating a window and pixel buffer that have differing sizes; the image will be stretched to fill the window.
- If the window supports the resize callback to correct the image aspect ratio, resizing the window will correct the matrix immediately, adding the black border as expected. This is a jarring effect when the texture size ratio is not an integer.
- This bug also causes issues with the new `resize_buffer()` API.
- The dependencies are a mess!
- Had to fork `imgui-wgpu`, which sits between 0.12 and 0.13 (has support for `winit` 0.24, but not `wgpu` 0.7)
- This is a temporary fix for CI, until https://github.com/Yatekii/imgui-wgpu-rs/pull/44 is merged and a new release of `imgui-wgpu` is out
- The WIP `wgpu` 0.7 update in https://github.com/parasyte/pixels/pull/134 will be needed for `imgui-wgpu` 0.14
- Update MSRV for `imgui` 0.7
This method is needed to let the user of the API configure the texture
format of the target texture/render texture that the surface texture is
rendered on. This texture format is hardware/platform dependent.
For example, this method makes it possible to use the pixels crate on
Android because Android seems not to use the previously hard-coded
texture format wgpu::TextureFormat::Bgra8UnormSrgb.
* Add Dear ImGui example
- Closes#90
* Change argument order to match `render_with`
* Remove unnecessary borrow
* Refactor error messages
* Add a space
* Refactor Gui field privacy
* Add a menu bar and allow the about window to be closed
- The local bool is necessary because the menu bar closures are not allowed to borrow `self` for mutable access while `imgui::Ui<'ui>` is alive.
- The token-based menu bar lifetime is even more verbose than this.
- I don't want to publish this crate.
- Can't publish pixels 0.2.0 if it depends on an internal unpublished crate.
- This requires allowing unsafe code, and removing the safety dance badge.
* WIP: Render API v2
* Fix doctests
* Expose all of PixelsContext (#110)
* Fix ScalingRenderer::new() taking &mut Device
* Replace getters with direct access to &mut PixelsContext
* Fix wrong reference type
* Fix unneeded mut
* Remove unnecessary mutable borrow, resurrect the shorter getter methods
* Initial port to wgpu master (0.6)
Surface creation is broken (see examples)
Does not support compressed textures
* Fix SurfaceTexture and examples
* Add support for compressed texture formats
* resize doesn't need mutability
* Update documentation
* Update wgpu
* Prepare release
* Goodbye Travis! Thanks for all the fish
