Screen Capture project

Post by Steve Lympany » 21 Sep 2010 18:58

Find attached a VIP3 project that captures the screen (picture), and displays it in a form.

It is simply an update of Rob K's work (Vitalik) (thanks Rob)

The project contains his dll in the EXE folder.

Maybe there are other ways, without the need for the DLL....??

I did capture of the screen (static picture only) as follows (2000 year, Visual Prolog 5.2):
1. The size of task window should be maximal.
2. The window should be transparent.
3. Capture of screen (VIP5.2):

Code: Select all

  task_win_eh(_Win,e_MouseDbl(_PNT,_ShiftCtlAlt,_Button),0):-!,         H = vpi_GetAttrVal(attr_screen_height),         % get screen height         W = vpi_GetAttrVal(attr_screen_width),          % get screen width         PICTURE = pict_GetFromWin(_Win,rct(0,0,W,H)),          % capture         PICTURE1 = pict_Rotate(PICTURE,pictRotate_180deg),  % rotation of "screen"         pict_Draw(_Win,PICTURE1,pnt(0,0),rop_SrcCopy),        %  :-))         pict_Destroy(PICTURE),         !.
This code till now works.
I believe, that the main idea is made in points 1 and 2.
