Have tried to obtain a screenshot from the ChromiumEmbedded browser for Delphi XE2/Firemonkey, but the ChromiumFMX.MakeScreenshot method only returns an empty bitmap.

Anyone have any idea how to obtain a bitmap?

Thx.

What version of Chromium do you have ? I can't find the MakeScreenshot method in the most recent one. – TLama
MakeScreenshot is part of FMX's TControl component, an ancestor of TChromiumFMX. What the version is concerned, found this in ceflib.pas. Is this useful? CEF_REVISION = 607; COPYRIGHT_YEAR = 2012; CHROME_VERSION_MAJOR = 18; CHROME_VERSION_MINOR = 0; CHROME_VERSION_BUILD = 1025; CHROME_VERSION_PATCH = 166; – Domus
Then it's not in the current trunk. There's even nothing with keyword Screenshot in the whole project. – TLama
I had hoped this was taken care of by TControl, but apparently doesn't function with TChromiumFMX. – Domus
Too bad TControl.MakeScreenshot isn't virtual; otherwise you could override it using Domus’s answer. – Martijn

Instead, use the following (be sure to instantiate YourBitmap prior to this call):

CefGetBitmap(ChromiumFMX.Browser, PET_VIEW, YourBitmap);
