= setPixel =
== Syntax ==
:{{void setPixel(int x, int y, int color)}}
== Arguments ==
:'''x'''
::X-coordinate (in pixels) of the relative position (originating top-left at 0, 0) in the control where you want to draw a pixel.
:'''y'''
::Y-coordinate (in pixels) of the relative position (originating top-left at 0, 0) in the control where you want to draw a pixel.
:'''color'''
::The ((RGB)) color value of the pixel to be drawn.
== Description ==
:Call setPixel to draw an individual pixel to an ((OWNERDRAW)) control.  First call ((startSetPixel)), then use setPixel or any of the ((Control drawing)) functions to draw to the control and finish with a call to ((endSetPixel)).  This function is not for setting pixels in the preview / final image; use ((pset)) for that instead.
== Example ==
<code>
%fml
ctl[0]: OWNERDRAW, Color=RGB(0,0,0), Size=(100,100)

OnFilterStart: {

// Get the size of the canvas
  int width, height;
  startSetPixel(0);
  width = getSetPixelWidth();
  height = getSetPixelHeight();

// Draw purple line at y = 100
  for (int xp = 0; xp < width; xp++) {
    setPixel(xp, 100, RGB(192,0,255));
  }

// Duplicate at y = 200 line at y = 100
  for (int xp = 0; xp < width; xp++) {
    setPixel(xp, 200, getPixel(xp, 100));
  }
  endSetPixel(0);

return false;
}
