Let's create the pdf_watchdog.py file, where we will write our Python code.įirst of all, we need to define script encoding, import libraries and define some variables.Ĭlass EventProcessor (pyinotify. Patool is a library for creating, extracting, testing archives, including in the RAR format. pyinotify binds these system calls and provides an implementation on top of them offering a generic andĪbstract way to manipulate those functionalities.įollow the official documentation to install pyinotify. Inotify is an event-driven notifier, its notifications are exported from kernel space to user space through three Pyinotify relies on a Linux Kernel feature (merged in kernel 2.6.13) called inotify. import PyPDF2 pdf 'YOUR PDF FILE PATH.pdf' pdf PyPDF2.PdfFileReader (pdf) page0 pdf.getPage (0) page0.scaleBy (0.5) float representing scale factor - this happens in. Pyinotify is a Python module for monitoring filesystems changes. This answer is really long overdue, and maybe the older versions of PyPDF2 didnt have this functionality, but its actually quite simple with version 1.26.0. We need the following Linux file system events: To do this, Linux has several file-specific events. Here it is important to track the moment when the file is completely ready and formed for further actions.įor example, it may turn out that the file is not yet fully copied to the directory. signaling to any external system that the archive is successfully ready.įor example, if the external system is Oracle, and you want to write the RAR file into database field.After the successful creation of the rar archive, a text file will be created, which will be a kind of marker.You need to wait, the file will be completely written to the disk, and only then you can work with it (otherwise the broken file will be archived, which then cannot be read). To disk cannot be called "ready to work". I tried reducing the dpi, however that do not change the pdf file size. However, on saving them as png file: ,dpi300) and then converting them to pdf using linux convert command the files are small. ![]() Pay attention to the phrase "the file is ready to work": a file that is still in the process of being written When I am saving the figure as a pdf file: ,dpi300) the figure size are quite big.
