Screen capture

alanuk · Post by **alanuk** » Mon Aug 02, 2004 2:37 pm

Is it possible, or is there a way to do a screen capture of an image displayed withing PB? Maybe there is a library function that will do it?

Any help welcomed.

Not amazingly sure what you wanted, but this code should grab your whole pb window and save it as a bmp in the folder where the source/exe is.

Code: Select all

#Screenshotimage=50
sourcedc=GetDC_(WindowID())
CreateImage(#Screenshotimage,WindowWidth(),WindowHeight())
UseImage(#Screenshotimage)
destdc=StartDrawing(ImageOutput())
BitBlt_(destdc,0,0,WindowWidth(),WindowHeight(),sourcedc,0,0,#SRCCOPY)
StopDrawing()
SaveImage(#Screenshotimage,"screenshot.bmp")

If this isnt what you wanted, then maybe a few more details would be helpful.

GreenGiant, many thanks for your comments and code. It looks as if it can be done. I will have a closer look at the code later.

Yes, I should have been a little more expicit !

I will have an opaque image of say 100 x 100 pixels with a transparent layer of the same size on top. I want to capture both layers as if they were one, ie what the eye sees.

Hope this helps.

Hi alanuk,

IIRC there is something like that in the code archive on purearea.net - can't recall what it is called though. Screenshot or something. Also a magnifier that might be mod-able.

Dare2, many thanks for your help. I did another search, with "screenshot" this time and found a lot of info just what I want to do.

Thanks guys for your help.
