# TeX Math to Image Conversion

This post functions as a quick development update on the **Math to Image Conversion Bot** (on Telegram), the **TeX math to image conversion** tool (at tools.timodenk.com), and the **API** that serves them both. The objective is to convert TeX math-code into images.

For example, the expression `\sum _{n=0}^{\infty }{\frac {f^{(n)}(a)}{n!}}\,(x-a)^{n}`

yields this image:This page on StackExchange gives a good overview about the math-expressions which can be used.

Both, the bot and the online tool, are using the same **API**. Source code and specification of which can be found on GitHub /Simsso/TeX2img-API.

The **Telegram** inline-bot let’s users send mathematical statements to their chat partner. Type `@math2img_bot`

into the input field, followed by the mathematical expression, to send rendered math images. Also, users can text the bot in a private chat and send expression or ask for examples with the `/sample`

command. The source code is available on Github /Simsso/Telegram-Math2Image-Bot. An example of usage is shown in the screenshot below.

The new **online tool** /tex-math-to-image-conversion simply converts a given expression into an image which can then be downloaded by the user. Supported file formats are SVG, PNG, BMP, and JPEG. This is what it looks like:
