Hi, is there a faster way of plotting pixels on a Image Canvas then using Pixels[x][y]?? I need to plot a pixel and then display it right away, so that the user can see the progress. For this purpose I created a function that calls Application->ProcessMessages until a certain time in mseconds has elapsed. This way every change on the canvas can be seen on the screen. But it is VERY slow. If I don''t include this function, only when the whole picture is completed the Canvas in repainted, which I don''t want. Like this: void MyWait(ms : word) { TDateTime t; t = Time(); while (Time() <= t + EncodeTime(0,0,0,ms)) Application->ProcessMessages(); } void PutPixel(int x, int y, TColor color) { Form1->Image1->Canvas->Pixels[x][y] = color; myWait(1); } PutPixel is called from a line and an arc drawing function. This method is slow. Is there another way? Thanks.
