Which piece of page content a render could not reproduce.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

PageContents

The page’s own content stream: nothing on the page was drawn.

Image

An image XObject or an inline image.

Form

A form XObject, and with it everything nested inside it.

XObject

A Do whose XObject resource is missing, is not a stream, or has no subtype this renderer knows how to draw.

Shading

A shading (sh or a shading pattern) this renderer could not load: a missing resource or a structural failure. All seven shading types paint.

Pattern

A pattern fill or stroke, painted as flat mid-gray instead of the pattern’s own content.

SoftMask

A mask that was ignored, so content the author masked out painted solid: an image /SMask or /Mask, or an /ExtGState /SMask.

BlendMode

A /BM blend mode painted as Normal. No longer produced — every ISO 32000 blend mode paints — but retained so report consumers keep compiling against the same set of kinds.

Annotation

An annotation appearance stream that was declared but could not be painted: unreadable, unparsable, or with no selectable state. Annotations that declare no appearance, and ones flagged Hidden or NoView, paint nothing by design and are not reported.

Glyph

A character code a painting font has no glyph for: the code advanced the text position but painted nothing. A single-byte code 0x20 is exempt — a space paints nothing whether or not the font maps it — while a two-byte 0x20 is a real CID and is reported. Text whose font paints at no tier (the GlyphPainting tier, or a load failure) is configured behavior and stays unreported; such a font still loads its metrics so the text advances.

TextClip

Text shown in a clipping rendering mode (Tr 4-7, ISO 32000-1 §9.3.6). The painting half of the mode is honored, but the glyph outlines never join the clipping path, so content the author clipped to the text paints unclipped.
