The 0.005 constant was added to width and height because, apparently, for certain texts Matplotlib is returning a slightly underestimated bounding box, i.e., smaller than required. These math equations went viral for being much more complicated than they seemed. # Adjust the figure size so it can hold the entire text. Width, height = bbox.size / float(dpi) + 0.005 # Now we can work with text's bounding box. # Saving the figure will render the text. And it is more than just drills, MathBoard encourages students to solve problems, and not just guess at answers. MathBoard will allow you to configure the app to best match the abilities of your individual child/student. MathBoard is a highly configurable math app appropriate for all school aged children. This saves the figure twice, but as is common in any text engine, the correct bounding box and other parameters can only be correctly obtained after the text has been rendered. for iOS, tvOS, macOS, and Windows 8 & 10.

The trick is to render the text, then get its bounding box, and finally adjust the figure size and the vertical positioning of text in the new figure.

Is there nothing devoted to just outputting equations, that won't require me to worry about all the extra space or position of the text? Syntax: (expression, environment) Parameters: expression A string which uses the standard Python expression syntax. I believe I could create a very large (space wise) figure, write the formula in the middle of the blank plot, save it, and use pixel analysis to trim it to as small an image as possible, but this seems rather crude.Īre plots the only intended output of matplotlib?

Note that this appears a blank image look to the left side of the displayįraction at coordinate (0,0) truncated and surrounded by whitespace If my formula involves fractions, and thus requires downward space, it is truncated, like in the image below. The result of that code is usually a tiny bit of text in the bottom left corner of a huge, white, blank image. However, the pyplot module is primarily for displaying graphs and plots, not the samples of text like I need. What I'd like to do is take TeX code from my python program which represents a mathematical expression, and save it to an image that can be displayed in my PyQt GUI, rather than displaying the equation in ugly plain text. Using the python library matplotlib, I've found what suggests to be a solution to this question:ĭisplaying (nicely) an algebraic expression in PyQt by utilising matplotlibs TeX markup.
