Changelog

2026.08.23

• Fill image fixtures with fast, deterministic pixel data and ensure png_too_large exceeds the VWS size limit

• Fix the _make_image_file docstring to document height as height, not width

• Fill CMYK image fixtures with CMYK 4-tuples instead of RGB triplets

• Include pixel value 255 when filling random image fixtures

• Add a jpeg_too_large fixture exceeding the Cloud Recognition 2 MiB limit.

• Add a pixel_count_too_large fixture exceeding Vuforia’s pixel limit.

• • Truncate corrupted_image_file so Pillow cannot open or repair it.

• • Use BMP instead of TIFF for the unsupported bad_image_file format.

• • Add a greyscale JPEG variant to image_files_failed_state.

• • Share failed-state image params between the single and parametrized fixtures.

• Add an empty_file fixture returning a zero-byte BytesIO.

• Add a grayscale_jpeg fixture returning a valid greyscale JPEG.

• Add an rgba_png fixture returning an RGBA PNG with transparency.

• • Clarify that high_quality_image’s historical rating of 5 is observational, not guaranteed.

• • Document that bundled high-quality JPEGs are not re-scored against live Vuforia in CI.

• • Assert the two high-quality image fixtures differ as pixel arrays, not only as bytes.

• • Return a fresh BytesIO from cached image bytes on each fixture call.

• • Cache expensive generated image bytes so they are not rebuilt every test.

• • Assert fixture images have the expected Pillow format, mode, and dimensions.

• • Add a test that corrupted_image_file raises when opened with Pillow.

• Pass PNG and JPEG optimization flags when saving generated image fixtures

• • Fill CMYK fixtures with four-channel pixels so JPEG+CMYK saves correctly.

• Add pytest ids to image_files_failed_state params for clearer failure names

• Add a png_just_under_max_size boundary-good Target API size fixture.

• Add an exif_oriented_jpeg fixture with EXIF Orientation set.

• Add an animated_gif multi-frame GIF fixture.

• Add a webp_image fixture returning a valid WebP image.

• Branch _make_image_file pixel filling on color_space so CMYK and RGB paths are distinct

• • Re-export image fixtures from the package root with an explicit __all__.

• • Document typed fixture exports. The package already includes py.typed.

• • Cache packaged JPEG resource bytes instead of reloading on every fixture call.

• • Document that image_file_success_state_low_rating does not guarantee a low Vuforia rating.

• • Add Path fixtures that write high-quality images to temporary files.

• Add ClearNamespaceParser to the root Sybil conftest setup.

• Add application_metadata_near_size_limit base64 metadata fixture.
