说明
pdftoppm converts PDF document pages to image formats (PPM, PGM, PBM, PNG, JPEG, TIFF). Part of the poppler-utils package, it renders each page as a raster image at the specified resolution. Output files are named with the provided prefix followed by a page number (e.g., image-001.png). Use -singlefile for a single page without numbering. The tool is commonly used for creating thumbnails, preparing PDFs for OCR, or converting documents for image-based workflows.
