Two programs I have used are:
1: ConEmu: Press
Win +
H keys to save its console display to a jpg file.
http://code.google.com/p/conemu-maximus5/
ConEmu-Maximus5 is a Windows console emulator with tabs, which presents multiple consoles and simple GUI applications as one customizable GUI window with various features.
2: FreeCpmmander: "Tool" menu has a screenshot option. (bmp png gif)

FreeCommander is an easy-to-use alternative to the standard windows file manager. The program helps you with daily work in Windows. Here you can find all the necessary functions to manage your data.
Both programs are part of my newLISP Windows command line programming tool set ;>)

I do not need to save the image to a file, I want to analyze it programmatically. Something similar to this:
Code: Select all
typedef struct point {
int x;
int y;
} Point;
Point points[] = {
{ 1, 10 },
{ 20, 3 },
{ 640, 480 },
{ 0, 0 }
};
COLORREF colors[4];
HDC h = GetDC(NULL); // handle of desktop
for( int i = 0; i < 4; i++ ) {
colors[i] = GetPixel(h, points[i].x, points[i].y);
}
ReleaseDC(h);

Try translate to newLISP:
Code: Select all
(import "user32" "GetDC") ; HDC GetDC(HWND hWnd);
(import "user32" "ReleaseDC") ; int ReleaseDC(HWND hWnd, HDC hDC);
(import "gdi32" "GetPixel") ; COLORREF GetPixel(HDC hdc, int nXPos, int nYPos);
(define (get-pixel point)
(letn ((h (GetDC 0))
(color (GetPixel h (first point) (last point))))
(ReleaseDC h)
color))
(print (map get-pixel '((1 10)
(20 3)
(640 480)
(0 0))))
;;-> (0 4144700 14548991 0)

Wow, it looks so amazing and easy! :) So, may be I move some my number-crunchers to C-DLLs. ;) Thanks!
