Method CaptureScreen.Pixels(+ 1 overload)

---

Overload

Gets pixel colors from a rectangle in screen.

public static uint[,] Pixels(RECT r)

Parameters

r  (RECT) Rectangle in screen.

Returns

uint[,] 2-dimensional array [row, column] containing pixel colors in 0xAARRGGBB format. Alpha 0xFF.

Exceptions

ArgumentException Empty rectangle.

AuException Failed. Probably there is not enough memory for bitmap of this size (width*height*4 bytes).

Examples

print.clear();
var a = CaptureScreen.Pixels(new(100, 100, 4, 10));
for(int i = 0, nRows = a.GetLength(0); i < nRows; i++) print.it(a[i,0], a[i,1], a[i,2], a[i,3]);

Overload(top)

Gets pixel colors from a rectangle in window client area.

public static uint[,] Pixels(wnd w, RECT? r = null, CIFlags flags = CIFlags.WindowDC)

Parameters

w  (wnd) Window or control.

r  (RECT?) Rectangle in w client area coordinates. If null, uses w.ClientRect.

flags  (CIFlags)

Returns

uint[,] 2-dimensional array [row, column] containing pixel colors in 0xAARRGGBB format. Alpha 0xFF.

Exceptions

AuWndException Invalid w.

ArgumentException The rectangle is empty or does not intersect with the window's client area.

AuException Failed. For example there is not enough memory for bitmap of this size (width*height*4 bytes).

Remarks

If flags contains WindowDC (default) or PrintWindow:

• If the window is partially or completely transparent, captures its non-transparent view.
• If the window is DPI-scaled, captures its non-scaled view. However r must contain scaled coordinates.
