D menu: frame before expansion
A 512x512 view of a restaurant menu card standing on a laid table, cutlery and glassware, warm evening light - the frame an outpainting tool is given, cropped from the published plate nss-d-menu_00001_.png. Its companion expands it to 704x704 with 96 pixels added on all four sides, and the boundary record in this group states the exact rectangle this image occupies inside that frame - so where it ended up can be checked rather than eyeballed.

Testing contract
Reference control- Scenario
- Feed this frame to an outpainting tool with the padding named in the boundary record, then find where this image ended up in what it returns.
- Expected result
- It is 512x512, and after a all-round expansion it must occupy exactly the rectangle 96,96,608,608. That is the claim worth testing: a tool that nudges or rescales the original by a few pixels still returns a picture that reads correctly.
What is a .png file?
PNG (Portable Network Graphics) is a raster image format using lossless DEFLATE compression. It supports full 8- or 16-bit-per-channel truecolor, palette, and greyscale modes with an optional alpha channel, but no animation. It is the standard choice for screenshots, logos, and graphics with sharp edges or transparency.
How to use this file
Use an example PNG to test image decoders, alpha-compositing, thumbnail generators, and format converters, or to verify that a pipeline preserves transparency and color depth on round-trip.
How to use this file for testing
“D menu: frame before expansion” is a deterministic Novus Examples fixture for Inpainting. Images with cut-out regions (rects, circles, corners, strips, irregular tears) and matching masks for testing inpainting, generative fill, content-aware fill, and object-removal pipelines.
Documented properties for this file: 512×512 · reference. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.
For image AI or enhancement tools, run the model or filter on this file and diff against the clean or ground-truth companion in the same group when available. Keep seeds and documented damage parameters in your evaluation notes so regressions are attributable.
Run your enhancement model on the degraded input and diff against the clean ground-truth companion in the same group; keep the documented degradation parameters and seed in your eval notes so scores are reproducible.

- pngA av f4: expanded canvasThe same view of head and shoulders portrait of an older white woman with short grey hair, plain cream background, expanded to 768x512 - 128 pixels added to the left and right, the symmetric case - so 33.3% of this frame is invented canvas. The original sits at pixels 128,0 to 640,512. Compare it INSET by 40 pixels: over that core it differs from the original by only 5.231/255, the VAE round trip, but over the whole rectangle by 6.293/255, because the pad deliberately feathers the original's outer edge into the new area. A test that expects the whole rectangle untouched fails on a correct tool.
