SVG images support by param.

Now you can add a SVG image content in a spec if you add name parameter to the image in the config.yaml and a map with the images content:

config.yaml:{
	...
	!image
		name:image1
}

spec: {
  	....
	images:{
		image1:{content: _svgContent}
	}
}
Dynamic images pages layout.

A new layout has been added to let you print a different number of pages dinamically. This version has tested only with images and text as content of the pages generated dynamically, but should work well with maps.
