how to get current stroke/fill color?
« on: May 15th, 2003, 2:34pm » |

This seems like a silly question, but I can't figure it out- stroke() and fill() will set the current stroke/fill colors, but how do I _get_ the current stroke and fill colors?
I would like to write some helper methods that do some drawing that will store the current stroke/fill colors before setting them and restore them before returning.
Perhaps stroke() and fill() can return the previous color after setting them?

void setup()
{
size(200,200);
background(255);
}
void draw()
{
fill( 255, 201, 0, 255 );
stroke( 0, 0, 0, 255 );
rectMode(CENTER_DIAMETER);
rect(width/2,height/2,width-20,height-20);
println( "fill \\ r: " + g.fillRi + ", g: " +
g.fillGi + ", b: " + g.fillBi + ", a: " +
g.fillAi );
println( "stroke \\ r: " + g.strokeRi +
", g: " + g.strokeGi + ", b: " + g.strokeBi +
", a: " + g.strokeAi );
}

color cFill, cStroke;
void setup()
{
size(200,200);
background(255);
fill( 255, 201, 0, 255 );
stroke( 0, 0, 0, 255 );
}
void loop()
{
rectMode(CENTER_DIAMETER);
rect(width/2,height/2,width-20,height-20);
}
void mousePressed()
{
storCurFill();
storCurStroke();
fill( 0, 104, 201, 255 );
}
void mouseReleased()
{
fill(cFill);
}
void storCurFill()
{
cFill = color(g.fillRi, g.fillGi, g.fillBi, g.fillAi);
}
void storCurStroke()
{
cStroke = color(g.strokeRi, g.strokeGi, g.strokeBi, g.strokeAi);
}

yipes, someone's been peeking at the code!
a necessary disclaimer for anything found inside the code and that we haven't documented... g.fillXX and the rest are not guaranteed to work like that forever, and may change.
the simplest way to do it is:
color f = g.filli;
or
color s = g.strokei;
but those may change to just g.fill (or just 'fill') and g.stroke (or just 'stroke') if it's something that people want to use a lot.

hehe 
i think it's cool to be able to have current stroke and fill values accessible globally. a few added bytes won't really hurt.

k, i've added this for 56:
color f = fill();
color s = stroke();
color b = background();
