Deterministic images with known properties for regression-testing resize, crop, convert, and filter pipelines.
Each card starts with one representative test file. Choose a use case, search, or filter to find a specific profile; a card’s variant menu contains its related samples.

Color And Metadata
A 16-bit (deep-colour) grayscale PNG holding a smooth 0–65535 gradient, for testing high-bit-depth support and spotting banding when a tool truncates to 8-bit.
Greyscale Set
A 16-step greyscale wedge from pure black to pure white, for testing tone reproduction, banding, and monitor calibration.
Greyscale Set
A flat 50% grey card (rgb 128,128,128), a reference for white balance and exposure testing.
Background Removal
A left-to-right alpha gradient over a solid colour, for testing how a viewer or compositor renders partial transparency.
Edge Cases
An 8-frame looping animated GIF of a moving dot. Tests animation handling, first-frame extraction, and GIF parsing.
Color And Metadata
The fruit still life as a baseline (sequential) JPEG, paired with a progressive JPEG of identical content for testing decode order and progressive-rendering support.
Greyscale Set
A pure black-and-white checkerboard, useful for testing scaling, aliasing, and edge handling.
Background Removal
A coffee mug photographed on a clean studio-white background: the easy input for a background remover, paired 1:1 with its transparent cut-out for scoring.
Colourize Set
Greyscale input for colourizing the fruit scene. Pair with the colour ground truth in this group.
Colourize Set
Greyscale input for colourizing the mug scene. Pair with the colour ground truth in this group.
Colourize Set
Greyscale input for colourizing the plant scene. Pair with the colour ground truth in this group.
Conditioning Maps
Colour ground-truth for the apple conditioning suite. Every map in this group is derived from this exact image, so a guided model's output can be scored against it.
