Page 1 Visual Quality Probe

Foreground diff: dark pixels are shared foreground, red is source-PDF-only foreground, and blue is HTML-only foreground.

Color heatmap: white pixels are background or excluded antialiased edges, gray is a close color match, and yellow through dark red indicates increasing perceptual color difference.

Fixture Expectations

These statements were extracted from the source PDF and describe the intended result.

The shadings should look like the reference imagelike the reference image
a + b: must be rendered to solid Black (100C100K) rectangles a + b: must be rendered to solid Green rectangles
c + d: must be rendered to solid Cyan rectangles
a + b: must be rendered to solid Red rectangles
c + d: must be rendered to solid White rectanglesIf a check mark is visible in the upper right corner then DeviceN is respected (= GOOD).

Checks


passed page-dimensions: Browser page dimensions match the PDF page dimensions.
passed text-run-count: The browser DOM contains the same number of text runs as the extracted layout.
passed word-boundaries: Rendered HTML text preserves word boundaries at the current threshold.
needs-review text-image-overlap: 2 text run(s) overlap rendered image boxes.
needs-review text-vector-overlap: 109 text run(s) overlap large rendered vector boxes.
passed visual-foreground-mask: PDF and browser foreground masks match within the current review thresholds after allowing a small renderer/browser rounding delta.
needs-review visual-color-difference: PDF and browser colors differ severely across a material share of stable foreground interiors.
