Measure(string, double, CssData, EventHandler<HtmlStylesheetLoadEventArgs>, EventHandler<HtmlImageLoadEventArgs>) : Size

Measure the size (width and height) required to draw the given html under given max width restriction. If no max width restriction is given the layout will use the maximum possible width required by the content, it can be the longest text line or full image width.

html: HTML source to render
maxWidth: optional: bound the width of the html to render in (default - 0, unlimited)
cssData: optional: the style to use for html rendering (default - use W3 default style)

imageLoad: optional: can be used to overwrite image resolution logic

Devuelve: the size required for the html

MeasureHtmlByRestrictions(HtmlContainer, Size, Size) : Size

Measure the size of the html by performing layout under the given restrictions.

htmlContainer: the html to calculate the layout for
minSize: the minimal size of the rendered html (zero - not limit the width/height)
maxSize: the maximum size of the rendered html, if not zero and html cannot be layout within the limit it will be clipped (zero - not limit the width/height)

Devuelve: return: the size of the html to be rendered within the min/max limits

ParseStyleSheet(string, bool) : CssData

Parse the given stylesheet to CssData object. If is true the parsed css blocks are added to the default css data (as defined by W3), merged if class name already exists. If false only the data in the given stylesheet is returned.

stylesheet: the stylesheet source to parse
combineWithDefault: true - combine the parsed css data with default css data, false - return only the parsed css data

Devuelve: the parsed css data

Render(DrawingContext, string, Point, Size, CssData, EventHandler<HtmlStylesheetLoadEventArgs>, EventHandler<HtmlImageLoadEventArgs>) : Size

Renders the specified HTML source on the specified location and max size restriction. If .Width is zero the html will use all the required width, otherwise it will perform line wrap as specified in the html If .Height is zero the html will use all the required height, otherwise it will clip at the given max height not rendering the html below it. Returned is the actual width and height of the rendered html.
