Tests: Remove all file(GLOB) from CMakeLists in Tests Using a file(GLOB) to find all the test files in a directory is an easy hack to get things started, but has some drawbacks. Namely, if you add a test, it won't be found again without re-running CMake. `ninja` seems to do this automatically, but it would be nice to one day stop seeing it rechecking our globbed directories. 2021-09-02 05:44:24 +00:00			`set(TEST_SOURCES`

Tests: Add benchmarks for `JPEGLoader` I'm the author of the image. 2023-03-28 15:51:48 +00:00			`BenchmarkJPEGLoader.cpp`
LibGfx: Correctly round values when computing the luminosity of a Color Truncating the value is mathematically incorrect, this error made the conversion to grayscale unstable. In other world, calling `to_grayscale` on a gray value would return a different value. As an example, `Color::from_string("#686868ff"sv).to_grayscale()` used to return #676767ff. 2024-05-13 14:55:29 +00:00			`TestColor.cpp`
LibGfx: Add DeltaE() function 2023-04-30 00:35:57 +00:00			`TestDeltaE.cpp`
LibGfx: Prevent out of bounds access when scaling small Bitmaps Since the color interpolation requires two pixels in the horizontal and vertical direction to work, 1 pixel wide or high bitmaps would cause a crash when scaling. Fix this by clamping the index into the valid range. Fixes #16047. 2022-11-16 10:38:51 +00:00			`TestGfxBitmap.cpp`
Tests: Add a basic ICC profile test icc-v4.jpg is Meta/Websites/serenityos.org/happy/3rd/bgianf.jpg. There are a whole bunch of jpgs with v4 color profiles and I just picked one fairly arbitrarily. It looks like a fairly standard v4 matrix profile that in this form is also present in many jpgs taken by mobile phone cameras. It uses parametric curves. icc-v2.png is based on ./Documentation/WebServer_localhost.jpg since that is the only image in the repo with a v2 color profile. It also has all kinds of interesting and somewhat exotic tags, such as an 'dscm' (an Apple extension to have a description of type 'mluc', since normal 'desc' is required ot have type 'desc' in v2 files -- in v4, 'desc' has type 'mluc') tag of type 'mluc' that actually contains data in several languages and that exercises the non-BMP UTF-16BE decoder. It's however still also a fairly standard v2 matrix profile, which uses 'curv' instead of 'para' for its curves ('para' is v4-only). I converted that jpeg file to png, and cropped most of the image data to save on file size by running: sips -s format png --cropToHeightWidth 21 42 in.jpg --out out.png 2023-01-29 18:05:21 +00:00			`TestICCProfile.cpp`

Tests: Add TestImageWriter For now, it tests that webps roundtrip, but it's easy to add basic roundtrip testing for other image formats. 2024-05-05 00:44:07 +00:00			`TestImageWriter.cpp`
LibGfx: Add an implementation of the MedianCut algorithm This is useful to find the best matching color palette from an existing bitmap. It can be used in PixelPaint but also in encoders of old image formats that only support indexed colors e.g. GIF. 2024-05-14 09:24:33 +00:00			`TestMedianCut.cpp`
LibGfx: Fix off-by-some in Painter::draw_scaled_bitmap_with_transform() Before this, drawing a 1x1 bitmap scaled up to MxN would only fill M/2 x N/2 pixel, due to source_point going outside (0, 0). 2024-01-10 02:29:16 +00:00			`TestPainter.cpp`
LibGfx+Everywhere: Change `Gfx::Rect` to be endpoint exclusive Previously, calling `.right()` on a `Gfx::Rect` would return the last column's coordinate still inside the rectangle, or `left + width - 1`. This is called 'endpoint inclusive' and does not make a lot of sense for `Gfx::Rect<float>` where a rectangle of width 5 at position (0, 0) would return 4 as its right side. This same problem exists for `.bottom()`. This changes `Gfx::Rect` to be endpoint exclusive, which gives us the nice property that `width = right - left` and `height = bottom - top`. It enables us to treat `Gfx::Rect<int>` and `Gfx::Rect<float>` exactly the same. All users of `Gfx::Rect` have been updated accordingly. 2023-05-21 22:41:18 +00:00			`TestRect.cpp`
Tests: Add tests to verify alpha values are premultiplied when scaling 2023-03-10 17:29:00 +00:00			`TestScalingFunctions.cpp`
LibGfx/WOFF: Ensure header `totalSfntSize` matches expected value 2023-10-23 20:48:15 +00:00			`TestWOFF.cpp`
LibGfx/WOFF2: Tolerate incorrect `totalSfntSize` in WOFF2 header The specification says that this value is for reference only, so we should be able to load a file where this value is incorrect. 2023-10-24 06:54:20 +00:00			`TestWOFF2.cpp`
