LaTeX equivalent to Google Chart API

问题:

I'm currently looking at different solutions getting 2 dimensional mathematical formulas into webpages. I think that the wikipedia solution (generating png images from LaTeX sourcecode) is good enough until we get support for MathML in webbrowsers.

I suddenly realized that it might be possible to create a Google Charts API equivalent for mathformulas. Has this already been done? Is it even possible due to the strange characters involved in LaTeX-code?

I would like to hit an url like latex2png.org/api/?eq="E = mc^2" and get the following response:

edit: Thanks for the answers sofar. However, I am already aware of several tools to generate png images from latex source code (both online and from my commandline), but what I was looking for was a simple way to get the image via an Http GET request. Perhaps such a service does not exist.

Update

As @hughes (and others) pointed out, the previous Google Chart API has been deprecated.

The example I wrote still works as of Sept 2015, but a new one shall be used now (documentation):

http://chart.googleapis.com/chart?cht=tx&chl=%5CLaTeX

Old answer

Google Chart can do it (Documentation):

http://chart.apis.google.com/chart?cht=tx&chl=%5CLaTeX

I'm using this with Google Docs, because it doesn't support math yet.

72pines.com More readable then chart.apis.google:

or chart.apis.google with background color changed

or chart.apis.google with background color transparent and resized

You could try the Online image generator for mathematical formulas for a start.

mathurl is a mathematical version of TinyURL.com. It allows you to reference LaTeXed mathematical expressions using a short url. For example, http://mathurl.com/?5v4pjw will show [LaTeX output Image] which you can then edit. More details on mathurl’s help page

I just ran across MathJax on Ajaxian:

MathJax seems to have a chance at being a practical solution that offers a high quality display of LaTeX and MathML math notation in HTML pages.

The output is remarkably beautiful, and it's all pure HTML and CSS, which makes it scalable and selectable. Performance is currently a bit sluggish, but this is recognized.

回答5:

There is a modern service called "mathtran" which provides a robust and fast way to this sort of thing: http://www.mathtran.org/

The big caveat is that only TeX math commands are allowed; AMSLaTeX, in particular, is not supported.

回答6:

As everyone has said, there are many services that do this already. Here is another easy one that I've used a number of times (and you can install it locally on your server if necessary):

回答7:

I'd take a good look at how the MediaWiki LaTeX support does it and borrow from there.

回答8:

Please check out this site for a way to create TeX documents without any software installed. You can then snippet the result image with any screen capture method and embed the resulting image into a any website.

Go to http://sharelatex.com

The software is free to use, but you need to register to create documents.
