The command you mentioned is using the "pdfimages" utility, which is typically part of the Poppler PDF library. It is a command-line tool used to extract images from a PDF document.
Let's break down the command:
- "pdfimages" is the name of the utility.
- "-p" is an option or flag which stands for "preserve the original order of images" when extracting them from the PDF file. This ensures the images are saved in the same order as they appear in the PDF.
- "${filename-pdf}" is a placeholder for the input PDF file. You should replace this with the actual file name or path of the PDF file you want to extract images from.
- "${filename_prefix}" is another placeholder for the output image files. This allows you to specify a prefix for the extracted image files. For example, if you provide "image" as the prefix, the extracted images will be saved as "image-1.ppm", "image-2.ppm", and so on.
Overall, this command would extract images from the specified PDF file while preserving their original order, and save them with the provided prefix followed by a numeric index and the ".ppm" extension.
