# expkg-zone58:image.thumbnailator
An XQuery interface to the image thumbnail generator library
[thumbnailator](https://github.com/coobird/thumbnailator) for BaseX 8.6.2+.
Tested against BaseX 8.6.2
Features size, scale, caption, rotate, flip, colorize, watermark. More details at [doc](doc/readme.md)
## Usage
Images are input and output as `xs:base64Binary` items. Inputs typically come from `fetch:binary`
which allows for file and http sources. Outputs may be saved with `file:write-binary` or `db:store`
### Simple
Create a thumbnail of given size
```xquery
import module namespace t="expkg-zone58:image.thumbnailator";
fetch:binary("http://images.metmuseum.org/CRDImages/ep/original/DT46.jpg")
=>t:size(80,60)
=>t:size(80)
```
or scale to a fraction of the original
```xquery
import module namespace t="expkg-zone58:image.thumbnailator";
fetch:binary("file:///Z:/recordings/radio/Book%20of%20the%20Week/image.png")
=>t:scale(0.25)
```
