The makedatauri macro constructs a data URI from a block of text and an associated ContentType. It is commonly used within stylesheets to generate an inline image or font.
! Parameters
|!Position |!Name |!Description |!Default |
|1st |text |Text to be converted to a data URI | |
|2nd |type |ContentType of text | |
! Examples
A trivial example to show how the macro works:
```
<<makedatauri "HelloThere" "text/plain">>
```
<<makedatauri "HelloThere" "text/plain">>
A user-defined macro such as this would typically be used within a stylesheet:
```
\define datauri(title)
<$macrocall $name="makedatauri" type={{$title$!!type}} text={{$title$}}/>
\end
```
Then one can write CSS rules like this:
```
background: url(<<datauri "$:/themes/tiddlywiki/starlight/ltbg.jpg">>);
```
