For this reason the browser is in // "off-screen mode" (OSR mode), it's encamsulated in a custom thread and it uses a different EXE for the // CEF subprocesses (ConsoleBrowser2_sp.exe). // While the custom browser thread is loading the webpage and capturing the screen, the console application is // waiting for an Event. // ConsoleBrowser2 reads the "/url" parameter and uses that URL to navigate and capture the screen. // For example : ConsoleBrowser2.exe /url=https://www.briskbard.com // If you need to debug this demo in Delphi using http://www.example.com click on the "Run->Parameters" menu option, // select the right target (Windows 32 bits / Windows 64 bits) and type "/url=http://www.example.com" (without quotes) // in the "Parameters" box. // By default the browser uses a virtual screen size of 1024x728 with 96 DPI (screen scale = 1) // If you need a different resolution or scale just edit those values in TEncapsulatedBrowser.Create // or add new command line switches with the new information. // The browser captures the screen when the main frame is loaded but some web pages need some extra time to finish. // This demo uses a 500 ms delay to avoid this problem and you can modify this value in TEncapsulatedBrowser.Create // CEF is configured in this demo to use "in memory" cache. As a result of this, the browser will always download // all the web page resources. Remember that if you switch to a local directory for the cache you will have problems // when you run several instances of this demo at the same time because Chromium doesn't allow sharing the same cache // by different processes. // This demo is configured to load the CEF binaries in the same directory were ConsoleBrowser2.exe is located but you // can set a different directory for the binaries by setting the GlobalCEFApp.FrameworkDirPath, // GlobalCEFApp.ResourcesDirPath and GlobalCEFApp.LocalesDirPath properties inside CreateGlobalCEFApp. // See the SimpleBrowser2 demo for more details. // CEF is configured to use ConsoleBrowser2_sp.exe for the subprocesses and it tries to find it in the same directory as // ConsoleBrowser2.exe but it's possible to use a different location for that EXE if you set a custom path in // GlobalCEFApp.BrowserSubprocessPath. // Most of the GlobalCEFApp properties must be the same in the main EXE and the EXE for the subprocesses. If you modify // them in CreateGlobalCEFApp then you'll also have to copy those property values in ConsoleBrowser2_sp.dpr // See the "SubProcess" demo for more details. begin try try CreateGlobalCEFApp; if WaitForMainAppEvent then WriteResult; except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; finally DestroyGlobalCEFApp; end; end.
