pdftocairo:tldr:f9433
The command "pdftocairo" is being used to convert a PDF file into JPEG image format.
Here's a breakdown of the command:
-
"pdftocairo": This is the name of the executable program or command-line tool that is being used to perform the PDF to image conversion. It could be a utility or program specific to your operating system.
-
"${filename-pdf}": This is a placeholder indicating that you need to provide the actual filename of the PDF file you want to convert. Replace "${filename-pdf}" with the actual name of the PDF file, including the file extension ".pdf".
-
"-jpeg": This flag is an option passed to the "pdftocairo" command, specifying that the output should be in JPEG image format. This option tells the program to convert the PDF file into multiple JPEG images. Each page of the PDF will be converted into a separate JPEG file.
Once you have the actual command with the PDF filename, for example:
pdftocairo mydocument.pdf -jpeg
The "pdftocairo" program will read the PDF file and convert it into a set of JPEG images, where each page of the PDF is represented as a separate JPEG file.
