ah ok, i get it.
Yeah like PhiLho said, its not possible.
But if you want to build your own, there are several examples on open processing. or take a look at this code. Dont know where i got it from but i saved it as i thought it might be useful.
Code:ColorPicker cp;
void setup()
{
size( 500, 500 );
frameRate( 100 );
cp = new ColorPicker( 10, 10, 400, 400, 255 );
}
void draw ()
{
background( 80 );
cp.render();
}
public class ColorPicker
{
int x, y, w, h, c;
PImage cpImage;
public ColorPicker ( int x, int y, int w, int h, int c )
{
this.x = x;
this.y = y;
this.w = w;
this.h = h;
this.c = c;
cpImage = new PImage( w, h );
init();
}
private void init ()
{
// draw color.
int cw = w - 60;
for( int i=0; i<cw; i++ )
{
float nColorPercent = i / (float)cw;
float rad = (-360 * nColorPercent) * (PI / 180);
int nR = (int)(cos(rad) * 127 + 128) << 16;
int nG = (int)(cos(rad + 2 * PI / 3) * 127 + 128) << 8;
int nB = (int)(Math.cos(rad + 4 * PI / 3) * 127 + 128);
int nColor = nR | nG | nB;
setGradient( i, 0, 1, h/2, 0xFFFFFF, nColor );
setGradient( i, (h/2), 1, h/2, nColor, 0x000000 );
}
// draw black/white.
drawRect( cw, 0, 30, h/2, 0xFFFFFF );
drawRect( cw, h/2, 30, h/2, 0 );
// draw grey scale.
for( int j=0; j<h; j++ )
{
int g = 255 - (int)(j/(float)(h-1) * 255 );
drawRect( w-30, j, 30, 1, color( g, g, g ) );
}
}
private void setGradient(int x, int y, float w, float h, int c1, int c2 )
{
float deltaR = red(c2) - red(c1);
float deltaG = green(c2) - green(c1);
float deltaB = blue(c2) - blue(c1);
for (int j = y; j<(y+h); j++)
{
int c = color( red(c1)+(j-y)*(deltaR/h), green(c1)+(j-y)*(deltaG/h), blue(c1)+(j-y)*(deltaB/h) );
cpImage.set( x, j, c );
}
}
private void drawRect( int rx, int ry, int rw, int rh, int rc )
{
for(int i=rx; i<rx+rw; i++)
{
for(int j=ry; j<ry+rh; j++)
{
cpImage.set( i, j, rc );
}
}
}
public void render ()
{
image( cpImage, x, y );
if( mousePressed &&
mouseX >= x &&
mouseX < x + w &&
mouseY >= y &&
mouseY < y + h )
{
c = get( mouseX, mouseY );
}
fill( c );
rect( x, y+h+10, 20, 20 );
}
