Download the software source and code to save an image from the site

In this post, I've provided you with a source and code ready for download that shows how to render an HTML document as an image using a WebBrowser object and a ViewObject.Draw method that, according to MSDN, draws a representation of an object in the specified device context. Slow, depicts. Before I start, I just want to mention that the results obtained were identical to those obtained from commercial libraries, so I hope this helps someone.

Below is a brief description of the parameters that the Draw method takes (this is the only method we will use):

• UInt32 dwDrawAspect - Specifies the drawing aspect. Valid values ​​are taken from DVASPECT enumerations. DVASPECT2 In this example, I'm using DVASPECT.CONTENT so the value sent is 1.
• int lindex - the part of the object of interest for the draw operation. Currently, only -1 is supported.
• IntPtr pvAspect - Pointer to additional information
• IntPtr ptd - describes the device for which the object is to be rendered. We will render for the default target device, so the value passed will be IntPtr.Zero.
• IntPtr hdcTargetDev - Information field for the target device indicated by the ptd parameter.
• IntPtr hdcDraw - The device context to draw on.
• red Rectangle lprc Bounds - the size of the captured image
• ref Rectangle lprcWBounds - the area of ​​the WebBrowser object we want to capture.
• IntPtr pfnContinue- pointer to a calling function (not used here).
• UInt32 dwContinue- value to pass as a parameter to the function (not used here).
