Math rendering

Example

The following maths code

<math> e^x = \sum_{n = 0}^{\infty} {x^n \over n!} = 1 + x + {x^2 \over 2!} + {x^3 \over 3!} + {x^4 \over 4!} + \cdots </math>

Gives the following output

[math]e^x = \sum_{n = 0}^{\infty} {x^n \over n!} = 1 + x + {x^2 \over 2!} + {x^3 \over 3!} + {x^4 \over 4!} + \cdots[/math]

Transparency

I replaced the line defining the ImageMagick convert command in /wiki/math/render.ml which makes it output a transparent PNG and also increases the quality by rendering the vector larger and downsizing with the default Mitchell filter. After making changes to render.ml, you must rebuild the texvc executable by issuing a make clean and make.

let cmd_convert tmpprefix finalpath = "convert -quality 100 -density 480 " \ ^ tmpprefix ^ ".ps -negate -unsharp 8 -resize 25% " ^ finalpath ^ " >/dev/null 2>/dev/null \ && convert " ^ finalpath ^ " -fill black -colorize 100% " ^ finalpath ^ ".png \ && composite -compose CopyOpacity " ^ finalpath ^ " " ^ finalpath ^ ".png " ^ finalpath
