Issues
There was a problem extracting the database on 13/11 due to duplicate entries in the math table, see 13 November 2006.
Example
The following maths code
|
<math>
</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 \
