screenshots in d3d

[ThePentiumGuy]

hey guys,

how would i take a screenshot(printscreen) of my d3d app?

if i try to do it, i end up getting a big green square.. which is supposedly my world..

 

any help would be appreciated, thanks

If I remember correctly (doing this from memory) you can just call 3D3Device.Getbackbuffer to get access your back buffer surface

 

Then Call Direct3D.SurfaceLoader.Save to save the surface that is returned from the 3D3Device.Getbackbuffer method.

 

Hope that Helps.

 

NOTE: Make sure you don't do a D3DDevice.clear before you save or u will save an empty image...

I wrote an example and uploaded it to my website yesterday. Its a little different then using the backbuffer (like createdbyx said) but similar:

i got it to work, a friend of mine (darc, from this forum) sent me his function, and it seems to work pretty well

 

PrivateFunction GetScreenCapture(ByVal FileName AsString, OptionalByVal FullScreen AsBoolean = False) As Image

 

' Captures the current screen and returns as an Image

 

' object

 

Dim objSK As SendKeys

 

Dim imgCapture As Image

 

If FullScreen = TrueThen

 

' Print Screen pressed twice here as some systems

 

' grab active window "accidentally" on first run

 

objSK.SendWait("{PRTSC 2}")

 

Else

 

objSK.SendWait("%{PRTSC}")

 

EndIf

 

Dim objData As IDataObject = Clipboard.GetDataObject()

 

ReturnCType(objData.GetData(DataFormats.Bitmap), Bitmap)

 

EndFunction

 

heh i have no idea how it works :),

 

thanks for your help guys, sorry, i couldnt get it to work tho

I would call that the worst method you can use because DirectX provides functionality to take screenshots. What didn't work for you while using D3D to take the screenshot?
