all,
I've been scouring the examples and the api for a way to create areas on an
image that can serve as both destinations and links to other pages in the
document. I have images with small areas that need to behave as links to other
pages or more precisely to specific text on other pages if possible. I also
need to have the reverse functionality where the text can act as a link back to
the specific area on the image. I've used Chunk's to create simple text links,
but I'm really coming up empty on how to overlay links onto images. Since there
doesn't seem to be a way to place a Chunk at an absolute x,y coordinate and I
need to tie the 'hit areas" to specific locations of the image, the Chunk
doesn't look to be a solution.
I've been looking at PdfContentByte, PdfDestination & PdfAction, but to be
blunt I'm in way over my head here. This is just a huge API to try to get a
grasp of in a couple of days;-( I've tried the following as an experiment, but
nothing appears at all and I don't see any evidence that local goto's are
active on the page with the image.
PdfContentByte ovrlay=pdfwri.getDirectContent();
for(int idx=0; idx<bubbles.length; idx++) {
float ctrX;
float ctrY;
float locX;
float locY;
int bubnum;
PdfContentByte cntbyt;
bubble=bubbles[idx];
ctrX=bubble.getField("centerX",0.0f);
ctrY=bubble.getField("centerY",0.0f);
bubnum=bubble.getField("bubbleNum",0);
locX=x+(ctrX*w);
locY=y+(ctrY*h);
cntbyt=new PdfContentByte(pdfwri);
cntbyt.setColorFill(Color.BLUE);
cntbyt.setColorStroke(Color.BLUE);
cntbyt.localGoto(LIST+"
"+sectionNumber+"-"+currentFigure+svcgrpdsc+" "+PART+bubnum, locX-5, locY-5,
locX+5, locY+5);
cntbyt.circle(locX,locY,5.0f);
ovrlay.add(cntbyt);
}
Any advice on how to do this gratefully accepted.
Bob
