fastget/setpixel

[A-man]

I know I asked almost this exact question a couple weeks ago, but this time it is regarding the new API. The fastsetpixel and fastgetpixel functions don't show up in the intellisense, and I'm not sure what the 'const bmp' is. I looked in the wiki, but it wasn't there yet.

Heres an example of using the canvas of the bitmap to set / get the color of the pixels really easy

var

BMP: TSCARBitmap;

begin

BMP := GetClient.CaptureEx(0,0,50,50);

Writeln(BMP.Canvas.Pixels[10, 10]); // Same as Fast get pixel

BMP.Canvas.Pixels[10, 10] := clRed; // Same as Fast set pixel

BMP.Free;

end.

Why use the canvas?

var

BMP: TSCARBitmap;

begin

BMP := GetClient.CaptureEx(0,0,50,50);

try

Writeln(BMP.Pixels[10, 10]); // Same as Fast get pixel

BMP.Pixels[10, 10] := clRed; // Same as Fast set pixel

finally

BMP.Free;

end;

end.

The canvas is A LOT slower, the Pixels property of TSCARBitmap is the actual replacement of the FastPixel API...

Didnt see the pixels property of the bitmap. Same principle tho.
