 The internal core html container Use GDI+ text rendering to measure/draw text. Init. Raised when the set html document has been fully loaded.
Allows manipulation of the html dom, scroll position, etc. Raised when the user clicks on a link in the html.
Allows canceling the execution of the link. Raised when html renderer requires refresh of the control hosting (invalidation and re-layout). There is no guarantee that the event will be raised on the main thread, it can be raised on thread-pool thread. Raised when Html Renderer request scroll to specific location.
This can occur on document anchor click. Raised when an error occurred during html rendering.
 There is no guarantee that the event will be raised on the main thread, it can be raised on thread-pool thread. Raised when a stylesheet is about to be loaded by file path or URI by link element.
This event allows to provide the stylesheet manually or provide new source (file or Uri) to load from.
If no alternative data is provided the original source will be used.
 Raised when an image is about to be loaded by file path or URI.
This event allows to provide the image manually, if not handled the image will be loaded from file or download from URI. The internal core html container Use GDI+ text rendering to measure/draw text.
 GDI+ text rendering is less smooth than GDI text rendering but it natively supports alpha channel thus allows creating transparent images. While using GDI+ text rendering you can control the text rendering using , note that using doesn't work well with transparent background. the parsed stylesheet data used for handling the html Gets or sets a value indicating if anti-aliasing should be avoided for geometry like backgrounds and borders (default - false). Gets or sets a value indicating if image asynchronous loading should be avoided (default - false).
True - images are loaded synchronously during html parsing.
False - images are loaded asynchronously to html parsing when downloaded from URL or loaded from disk.
 Asynchronously image loading allows to unblock html rendering while image is downloaded or loaded from disk using IO ports to achieve better performance.
Asynchronously image loading should be avoided when the full html content must be available during render, like render to image. Gets or sets a value indicating if image loading only when visible should be avoided (default - false).
True - images are loaded as soon as the html is parsed.
False - images that are not visible because of scroll location are not loaded until they are scrolled to. Images late loading improve performance if the page contains image outside the visible scroll area, especially if there is large amount of images, as all image loading is delayed (downloading and loading into memory).
Late image loading may effect the layout and actual size as image without set size will not have actual size until they are loaded resulting in layout change during user scroll.
Early image loading may also effect the layout if image without known size above the current scroll location are loaded as they will push the html elements down. Is content selection is enabled for the rendered html (default - true).
If set to 'false' the rendered html will be static only with ability to click on links. Is the build-in context menu enabled and will be shown on mouse right click (default - true) The scroll offset of the html.
This will adjust the rendered html by the given offset so the content will be "scrolled".
 Element that is rendered at location (50,100) with offset of (0,200) will not be rendered as it will be at -100 therefore outside the client rectangle. The top-left most location of the rendered html.
This will offset the top-left corner of the rendered html. The max width and height of the rendered html.
The max width will effect the html layout wrapping lines, resize images and tables where possible.
The max height does NOT effect layout, but will not render outside it (clip).

 GDI vs. GDI+ text rendering
Windows supports two text rendering technologies: GDI and GDI+.
GDI is older, has better performance and looks better on standard monitors but doesn't support alpha channel for transparency.
GDI+ is newer, device independent so work better for printers but is slower and looks worse on monitors.
HtmlRender supports both GDI and GDI+ text rendering to accommodate different needs, GDI+ text rendering methods have "GdiPlus" suffix in their name where GDI do not.
 Rendering to image
See https://htmlrenderer.codeplex.com/wikipage?title=Image%20generation
Because of GDI text rendering issue with alpha channel clear type text rendering rendering to image requires special handling.
Solid color background - generate an image where the background is filled with solid color and all the html is rendered on top of the background color, GDI text rendering will be used. (RenderToImage method where the first argument is html string)
Image background - render html on top of existing image with whatever currently exist but it cannot have transparent pixels, GDI text rendering will be used. (RenderToImage method where the first argument is Image object)
Transparent background - render html to empty image using GDI+ text rendering, the generated image can be transparent. Text rendering can be controlled using , note that doesn't render well on transparent background. (RenderToImageGdiPlus method)
 Overwrite stylesheet resolution
Exposed by optional "stylesheetLoad" delegate argument.
Invoked when a stylesheet is about to be loaded by file path or URL in 'link' element.
Allows to overwrite the loaded stylesheet by providing the stylesheet data manually, or different source (file or URL) to load from.
Example: The stylesheet 'href' can be non-valid URI string that is interpreted in the overwrite delegate by custom logic to pre-loaded stylesheet object
If no alternative data is provided the original source will be used.
 Overwrite image resolution
Exposed by optional "imageLoad" delegate argument.
Invoked when an image is about to be loaded by file path, URL or inline data in 'img' element or background-image CSS style.
Allows to overwrite the loaded image by providing the image object manually, or different source (file or URL) to load from.
Example: image 'src' can be non-valid string that is interpreted in the overwrite delegate by custom logic to resource image object
Example: image 'src' in the html is relative - the overwrite intercepts the load and provide full source URL to load the image from
Example: image download requires authentication - the overwrite intercepts the load, downloads the image to disk using custom code and provide file path to load the image from.
If no alternative data is provided the original source will be used.
Note: Cannot use asynchronous scheme overwrite scheme.

The max height does NOT effect layout, but will not render outside it (clip).
can exceed the max size by layout restrictions (unwrap-able line, set image size, etc.).
Set zero for unlimited (width/height separately).
 ScrollOffset:
This will adjust the rendered html by the given offset so the content will be "scrolled".
Element that is rendered at location (50,100) with offset of (0,200) will not be rendered at -100, therefore outside the client rectangle. LinkClicked event
Raised when the user clicks on a link in the html.
Allows canceling the execution of the link to overwrite by custom logic.
If error occurred in event handler it will propagate up the stack. StylesheetLoad event:
Raised when a stylesheet is about to be loaded by file path or URL in 'link' element.
Allows to overwrite the loaded stylesheet by providing the stylesheet data manually, or different source (file or URL) to load from.
Example: The stylesheet 'href' can be non-valid URI string that is interpreted in the overwrite delegate by custom logic to pre-loaded stylesheet object
If no alternative data is provided the original source will be used.
 ImageLoad event:
Raised when an image is about to be loaded by file path, URL or inline data in 'img' element or background-image CSS style.
Allows to overwrite the loaded image by providing the image object manually, or different source (file or URL) to load from.
Example: image 'src' can be non-valid string that is interpreted in the overwrite delegate by custom logic to resource image object
Example: image 'src' in the html is relative - the overwrite intercepts the load and provide full source URL to load the image from
Example: image download requires authentication - the overwrite intercepts the load, downloads the image to disk using custom code and provide file path to load the image from.
If no alternative data is provided the original source will be used.
 Refresh event:
Raised when html renderer requires refresh of the control hosting (invalidation and re-layout).
There is no guarantee that the event will be raised on the main thread, it can be raised on thread-pool thread. RenderError event:
Raised when an error occurred during html rendering.
 Main adapter to framework specific logic. parser for CSS data the root css box of the parsed html list of all css boxes that have ":hover" selector on them Handler for text selection in the html. Handler for downloading of images in the html the text fore color use for selected text the back-color to use for selected text the parsed stylesheet data used for handling the html Is content selection is enabled for the rendered html (default - true).

Is the build-in context menu enabled (default - true) Gets or sets a value indicating if anti-aliasing should be avoided for geometry like backgrounds and borders Gets or sets a value indicating if image asynchronous loading should be avoided (default - false).
 Gets or sets a value indicating if image loading only when visible should be avoided (default - false).
 is the load of the html document is complete the top-left most location of the rendered html the max width and height of the rendered html, effects layout, actual size cannot exceed this values.
Set zero for unlimited.
 Gets or sets the scroll offset of the document for scroll controls The actual size of the rendered html (after layout) the top margin between the page start and the text the bottom margin between the page end and the text the left margin between the page start and the text the right margin between the page end and the text Init. parser for CSS data Raised when the set html document has been fully loaded.
Allows manipulation of the html dom, scroll position, etc. Raised when the user clicks on a link in the html.
Allows canceling the execution of the link. Raised when html renderer requires refresh of the control hosting (invalidation and re-layout). There is no guarantee that the event will be raised on the main thread, it can be raised on thread-pool thread. Raised when Html Renderer request scroll to specific location.
This can occur on document anchor click. Raised when an error occurred during html rendering.
 There is no guarantee that the event will be raised on the main thread, it can be raised on thread-pool thread. Raised when a stylesheet is about to be loaded by file path or URI by link element.
This event allows to provide the stylesheet manually or provide new source (file or Uri) to load from.
If no alternative data is provided the original source will be used.
 Raised when an image is about to be loaded by file path or URI.
This event allows to provide the image manually, if not handled the image will be loaded from file or download from URI. the parsed stylesheet data used for handling the html Gets or sets a value indicating if anti-aliasing should be avoided for geometry like backgrounds and borders (default - false). Gets or sets a value indicating if image asynchronous loading should be avoided (default - false).
True - images are loaded synchronously during html parsing.
False - images are loaded asynchronously to html parsing when downloaded from URL or loaded from disk.
 Asynchronously image loading allows to unblock html rendering while image is downloaded or loaded from disk using IO ports to achieve better performance.
Asynchronously image loading should be avoided when the full html content must be available during render, like render to image. Gets or sets a value indicating if image loading only when visible should be avoided (default - false).
True - images are loaded as soon as the html is parsed.
False - images that are not visible because of scroll location are not loaded until they are scrolled to. Images late loading improve performance if the page contains image outside the visible scroll area, especially if there is large amount of images, as all image loading is delayed (downloading and loading into memory).
Late image loading may effect the layout and actual size as image without set size will not have actual size until they are loaded resulting in layout change during user scroll.
Early image loading may also effect the layout if image without known size above the current scroll location are loaded as they will push the html elements down. Is content selection is enabled for the rendered html (default - true).
If set to 'false' the rendered html will be static only with ability to click on links. Is the build-in context menu enabled and will be shown on mouse right click (default - true) The scroll offset of the html.
This will adjust the rendered html by the given offset so the content will be "scrolled".
 Element that is rendered at location (50,100) with offset of (0,200) will not be rendered as it will be at -100 therefore outside the client rectangle. The top-left most location of the rendered html.
This will offset the top-left corner of the rendered html. The max width and height of the rendered html.
The max width will effect the html layout wrapping lines, resize images and tables where possible.
The max height does NOT effect layout, but will not render outside it (clip).
can be exceed the max size by layout restrictions (unwrapable line, set image size, etc.).

If the "br" tag is after inline box then the anon block will have zero height only acting as newline, but if it is after block box then it will have min-height of the font size so it will create empty line. the current box to correct its sub-tree used to know if the br is following a box so it should create an empty line or not so it only move to a new line Correct DOM tree if there is block boxes that are inside inline blocks.
Need to rearrange the tree so block box will be only the child of other block box. the current box to correct its sub-tree Rearrange the DOM of the box to have block box with boxes before the inner block box and after. the box that has the problem Split bad box that has inline and block boxes into two parts, the left - before the block box and right - after the block box. the parent box that has the problem the box to split into different boxes the left block box that is created for the split Makes block boxes be among only block boxes and all inline boxes have block parent box.
Inline boxes should live in a pool of Inline boxes only so they will define a single block.
At the end of this process a block box will have only block siblings and inline box will have only inline siblings. the current box to correct its sub-tree Check if the given box contains only inline child boxes in all subtree. the box to check true - only inline child boxes, false - otherwise Check if the given box contains inline and block child boxes. the box to check true - has variant child boxes, false - otherwise Parses the source html to css boxes tree structure. the html source to parse Add html text anon box to the current box, this box will have the rendered text
