SVG cloud word.

This lib generate SVG cloud word?

At the moment it only outputs to a PNG file, but in theory it wouldn't be hard to modify it to support SVG.

	fn generate_from_word_positions(
	rng: &mut WyRand,
	width: u32,
	height: u32,
	word_positions: Vec<Word>,
	scale: f32,
	background_color: Rgba<u8>,
	color_func: fn(&Word, &mut WyRand) -> Rgba<u8>
	) -> RgbaImage {
	// TODO: Refactor this so that we can fail earlier
	if !(0.0..=100.0).contains(&scale) {
	// TODO: Idk if this is good practice
	// println!("The scale must be between 0 and 100 (both exclusive)");
	exit(1);
	}
	let mut final_image_buffer = RgbaImage::from_pixel((width as f32 * scale) as u32, (height as f32 * scale) as u32, background_color);
	for mut word in word_positions.into_iter() {
	let col = color_func(&word, rng);
	if scale != 1.0 {
	word.font_size.x *= scale;
	word.font_size.y *= scale;
	word.position.x *= scale;
	word.position.y *= scale;
	word.glyphs = text::text_to_glyphs(word.text, word.font, word.font_size);
	}
	text::draw_glyphs_to_rgba_buffer(&mut final_image_buffer, word.glyphs, word.font, word.position, word.rotated, col);
	}
	final_image_buffer
	}

This function could be changed to place the words in an SVG file since all the necessary data is there: word, font size, x, y.

Cool! i am starting change here will try make this feature. Still not working yet

Looks good! Excited to try it out.

I checked out your branch and was able to modify it to get an SVG word cloud. Everything is slightly off because of the rendering differences between theab_glyph library used for calculating word positions and SVG though. Let me know if you're interested in trying to take this further and I can make a PR on your repo with the code.

This feature would be dope! have not found any other wordcloud implementation supporting svg

Hello @isaackd Yes, I am interested in help. If you can do the PR to fix it I'll be happy. I can generate the svg but I still can't create the cloud itself.

Yes, I couldn't generate the svg, now I can't create the cloud.
I want to create another function to allow me to generate only svg and keep the png generation function as it is today.
