recolor_vectors
Make non-image page content gray
Usage
pdftl
<input>recolor_vectors[<pages>...]output<output>
Details
The recolor_vectors operation converts color-setting instructions within PDF
content streams. Currently it only supports grayscale conversion. The UI is expected to change.
Note: This modifies vector path geometry, text coloring operators, and layout boundaries. Raster image payloads (XObjects) are skipped by this operation.
Examples
Convert non-image elements on pages 1-3 to grayscale
pdftl in.pdf recolor_vectors 1-3 output out.pdf
Convert non-image elements on all pages to grayscale
pdftl in.pdf recolor_vectors output out.pdf
