Hello,
I am trying to make a screenshot of the actual WebGMap component.
With the standard delphi functions I only get black screenshots:
gMap: TTMSFMXWebGMaps;
...
Image1 := TImage.Create( FHaupt );
Image1.Bitmap := FHaupt.gMap.MakeScreenshot;
Image1.Bitmap.SaveToFile( cFilename );
is ist wrong way or someone knows how to do it ?
XE6
firemonkey Android
thanks
No one with same problem or an idea?
Searching through whole google, it looks no one else has this problem.
I just want to save the screenshot of the google-maps component.
I tried to put the TTMSFMXWebGMaps component on different owners (panels, forms, tabsheets etc),
I tried different scalings,
I tried to copy from the canvas with "DrawtoDC" and a lot of different functions.
There is no pixel to get.
The simpliest test see below. There is a form with TTMSFMXWebGMaps, TImage, a button and two radiobutton.
No style, nothing else.
The MakeScreenshot of the button shows the buttonimage,
the MakeScreenshot of GMaps shows nothing.
No error, and no image.
I am using XE6 .
With firemonkey Android and firemonkey Win32 same effekt.
Help is very welcome!
