CefSharp.OffScreen

An offscreen instance of Chromium that you can use to take snapshots or evaluate JavaScript.

Contains the last rendering from Chromium.

Need a lock because the caller may be asking for the bitmap while Chromium async rendering has returned on another thread.

Size of the Chromium viewport. This must be set to something other than 0x0 otherwise Chromium will not render, and the ScreenshotAsync task will deadlock.

Create a new OffScreen Chromium Browser

Initial address (url) to load The browser settings to use. If null, the default settings are used.

Immediately returns a copy of the last rendering from Chrome, or null if no rendering has occurred yet. Chrome also renders the page loading, so if you want to see a complete rendering, only start this task once your page is loaded (which you can detect via FrameLoadEnd or your own heuristics based on evaluating JavaScript). It is your responsibility to dispose the returned Bitmap. The bitmap size is determined by the Size property set earlier.

Starts a task that waits for the next rendering from Chrome. Chrome also renders the page loading, so if you want to see a complete rendering, only start this task once your page is loaded (which you can detect via FrameLoadEnd or your own heuristics based on evaluating JavaScript). It is your responsibility to dispose the returned Bitmap. The bitmap size is determined by the Size property set earlier.

Has Focus - Always False

returns false

Fired by a separate thread when Chrome has re-rendered. This means that a Bitmap will be returned by ScreenshotOrNull().

Get/set the size of the Chromium viewport, in pixels. This also changes the size of the next screenshot.
