![]() Something you may test is explicitly adding default optional parameters to see if that works. That's why your original code was working fine. It shouldn't hurt to put in the empty quotes, but it isn't necessary if you explicitly state your parameter. I.e., since you put "resolution = 200" instead of just "200", Python should be able to figure out which parameter you are talking about. In your case, Python throws an error because you are defining parameter 6 in parameter 3's location.Įdit: I did some research and learned that you don't need to put in parameter space fillers if you explicitly state the parameter name in your code. ![]() Python isn't smart enough to figure out the order of parameters without explicitly telling it what is what. You don't need to put quotes in for parameters after the last one you have defined. The empty quotes are place markers.Įxample: (mxd, project, "", "", "", resolution = 200) Since resolution is the 6th parameter, you shouldn't place it directly after parameter 2 (out_jpeg). You need to include empty quotes for parameters you aren't changing. It seems like it changes every time I alter my script. The weird part is I can't seem to find any pattern or reason to the maps I'm getting these errors on. I've tried multiple tests to see if my syntax is wrong, and if the script is using too many resources and crashing, but haven't been able to figure out what my issue is. In the other form, I copy the () line over and over with the parameters for each map specified, as below: mxd = (r"Y:\Maps\map1.mxd") In one I loop through an array of directories and pull the individual mxd files into the export command, as below: for line in Direct:Ī(mxd, project, resolution = 200) I've tried two main ways of running this process. I've alternatively been getting a Visual C++ Runtime error saying python experienced an abnormal program termination, or the program throws an exception saying "AttributeError: PageLayoutObject: Error in executing ExportToJPEG" If you want to save matplotlib figures as individual files, you can do this with the savefig function.I'm attempting to writing a python script that will automate exporting a set of stock maps to JPEG from their mxd files, and I'm having some strange issues getting there. If you want to save figures in a single file, use the saveas function instead. Matplotlib is a python plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments across platforms. The course below is all about data visualization:ĭata Visualization with Matplotlib and Python Save figureįor those who didn’t know, matplotlib savefig creates a file of the current figure as a PNG (with transparency), and saves it to your filesystem. So Matplotlib can save plots directly to a file using savefig(). In this article we won’t cover the installation of matplotlib, if you want to install it see the installation faq. Savefig is useful when you need to save a figure for viewing outside of matplotlib, such as in another program, or when you want to use a vector graphics program (Inkscape, Illustrator, etc.) to modify it. It’s also useful if you want to save a copy of a figure in the same directory as your matplotlib script. ![]() It decides on the image format based on the extension. For example to save a jpg image named figure1. The figure image must have an extension of jpg, png, or pdf. The savefig() method is part of the matplotlib.pyplot module. ![]() This saves the contents of your figure to an image file. It must have the output file as the first argument. You can add the full path, relative path or no path. To change the format, simply change the extension like so: The most basic program you can do is just 5 lines of code: import matplotlib.pyplot as plt If you don’t define a path, it will save the image in the current working directory. If you use Linux, you can use the command below: You can open your file with any external image program, because it’s just a regular image. Or open it in an image or pdf viewer if you saved it as pdf A plot saved to a pdf Additional savefig optionsĪ number of new savefig options have been added to matplotlib. The options are: savefig(filename, dpi= None, format= 'png', bbox_inches= 'tight', pad_inches= 0.2, bbox= None, pad= None, dashes= None, loc= 'upper left', rot= 0, vmax= 'I', vmin= 'I', hmax= 'I', hmin= 'I') Graphmatica save as image pdf#
