Use cases

Debug text renderingUnderstand why text does not appear, is reversed, or is in the wrong place (matrices, clipping, order).
Identify displayed imagesIdentify which resources (XObject) are drawn on a page and in what order (Do operator).
Technical analysis / reverseStudy a PDF generated by a third-party tool to understand its content structure (ops and parameters).

What you get

A JSON per page listing the operators and their operands (execution order preserved).

Actionable information to write detection rules (e.g., pages without text, presence of transformations, etc.).

Limits and points of attention

Very technical output: it reflects the PDF description language, not a "human" representation of the content.
Streams may be compressed/filtered: extraction depends on the engine's ability to decode them.
En PDF grandes, la exportación puede ser voluminosa: apunte a una página/rango si es posible.

Frequently asked questions

Does this replace text extraction?

No. It is a debugging tool: it shows low-level operations, not the reconstructed text.

I see a lot of "q" and "Q", is that normal?

Yes: these are very frequent graphic state (stack) saves/restorations.

¿Para qué sirve "cm"?

Es una transformación (matriz) aplicada al sistema de referencia: a menudo la causa de posiciones/rotaciones inesperadas.

Tip

Debug tip: look for sequences around "Tj/TJ" (text) and "Do" (XObject) to understand the actual display order on the page.
