replicate() problem

Hello all,
I am trying to replicate a few sections of a source image to a new image. I am using the syntax: target.replicate(source, src x,src y,w,h, targ x targ y, w, h);.
The problem I am finding is that only the first replicate command works and seemingly only if it is copying from close to 0,0.
Here is the code Im using. I'd appreciate some ideas. Is this a bug (or am I due for a forehead slap?).
Code:
String imgFileName;
BImage img, tileImg;
void setup(){
imgFileName = "anyImage.jpg";
int dimX, dimY;
img=loadImage(imgFileName);
dimX=img.width; dimY=img.height;
tileImg=new BImage(dimX,dimY);
size(dimX,dimY);
background(255);
tiles(img, tileImg);
image(tileImg,0,0);
}
void tiles(BImage _img, BImage _tileImg){
BImage img = _img;
BImage tileImg=_tileImg;
int iw,ih; //xs and ys are the spacer vals, iw, ih are img height and width
iw=30; //replicated img width
ih=15; //replicated img height
//works
tileImg.replicate(img, 0,0,iw,ih,
0,0,iw,ih);
// these do not work!
tileImg.replicate(img, 50,50,iw,ih,
50,50,iw,ih);
tileImg.replicate(img, 20,20,iw,ih,
20,20,iw,ih);
} |

Hm, the basic syntax of the replicate function is incorrect. Perhaps from an older reference? I reworked your tiles() function (using the syntax replicate(srcImg, sx1, sy1, sx2, sy2, dx1, dy1, dx2, dy2)), so this should do the trick:
Code:
void tiles(BImage _img, BImage _tileImg){
BImage img = _img;
BImage tileImg=_tileImg;
int iw,ih; //xs and ys are the spacer vals, iw, ih are img height and width
iw=60; //replicated img width
ih=30; //replicated img height
// the upper left position of the square you want to replicate.
int sourceXpos = 130;
int sourceYpos = 60;
// the destination of the replicated area.
int destXpos = 5;
int destYpos = 5;
tileImg.replicate(img,
sourceXpos,sourceYpos,
iw+sourceXpos,ih+sourceYpos,
destXpos,destYpos,
iw+destXpos,ih+destYpos );
}

Hope it helps. Cheers.
