## WordCloud ☁
#### A simplified way to create Wordclouds in Rust.
### Simple Example
```rust
use wordcloud::*;
use wordcloud::font::*;
let mut font_data = Vec::from(include_bytes!("font.ttf") as &[u8]);
let font_set = FontSetBuilder::new()
.push(Font::from_data(&mut font_data).unwrap())
.build();
let output_dimensions = Dimensions::from_wh(1000, 1000);
let wc = WordCloudBuilder::new()
.dimensions(output_dimensions)
.font(&font_set)
.build()
.unwrap();
let input_text = io::read_string_from_file("input_text.txt").unwrap();
let ranked = RankedWords::rank(input_text.split_whitespace().collect());
wc.write_content(ranked, 2000);
wc.export_rendered_to_file("output.svg").unwrap();
```
## Using Stopwords
```rust
use wordcloud::*;
use wordcloud::font::*;
// Create the default StopWords set using the "stopwords" crate feature
let stop_words = StopWords::default();
let input_text = io::read_string_from_file("input_text.txt").unwrap();
let ranked = RankedWords::rank(
input_text
.split_whitespace()
// filter out the StopWords using the iterator function
// a similar named function also exists for rayon's ParallelIterators
.filter_stop_words(&stop_words)
// filter out everything that is just a number
.filter(
|x| x.parse::().is_err()
)
.collect()
);
// ...
```
## Using Background Images
```rust
use wordcloud::*;
// ...
let image = image::load_from_memory(test_image).expect("image load failed");
let wc = WordCloudBuilder::new()
.dimensions(output_dimensions)
.font(&font_set)
.image(&image)
.build()
.unwrap();
// ...
```
