![]() ![]() ![]() My PDF files contain simple plots which consist of (a) data points only, (b) lines between data points (data points not plotted), or (c) both data points and lines. Pylab.savefig(outfile,bbox_inches='tight') I use a home-grown code whose starting point was an example code on matplotlib website. My goal is to reduce the plot files that I produce with matplotlib. These file sizes cause programs that use them to come to a grinding halt. I can generate files that are 100's of KB or even MBs. The problem is that the output files (the PDF files containing plots that are generated with matplotlib) are huge. I use matplotlib to generate x-y data plots i.e., 2-D plots. Write_log ( 'The file doesnt exist: ' + event. pathname ) ) # creating txt-markerį = open ( dir + event. name + '.rar.txt' ) # creating rar archive name + '.rar' ) # if TXT-marker exists, delete it too if os. name ) = '.pdf' : # if RAR-file already exists, delete it if os. pathname ) ) def process_IN_CLOSE_WRITE (self, event ) : pathname ) ) def process_IN_MOVED_TO (self, event ) : pathname ) ) def process_IN_MOVED_FROM (self, event ) : pathname ) ) def process_IN_DELETE_SELF (self, event ) : pathname ) ) def process_IN_DELETE (self, event ) : _call_ (event ) def process_IN_CREATE (self, event ) : ProcessEvent ) : def _init_ (self, callback ) :ĭef _call_ (self, event ) : if not suffix_filter (event ) : super (EventProcessor, self ). 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. Pyinotify is a Python module for monitoring filesystems changes. 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". Pay attention to the phrase "the file is ready to work": a file that is still in the process of being written When the pdf file appears and ready to work, archiving in rar will start.On a Linux server, this can be done by creating a watchdog script in Python 3Īnd the patool package. RAR compression provides nearly 20x PDF compression and is currently the best compression algorithm for pdf The most efficient way to save server space is to compress PDF to RAR. Storing large PDFs (over 2GB) wastes server space and causes problems when downloading with Google Chrome. ![]()
