Just so you know what the code looks like (nothing fancy at all), here
is the action within my Orders controller. By commenting out the
setFilePath it should output to the browser:
function storeBarcode($oid) {
$this->layout=NULL;
$this->autoRender = false;
$bc = new DataMatrix();
$bc->setBGColor("WHITE");
$bc->setBarColor("BLACK");
$bc->setEncoding("AUTO");
$bc->setFormat("8x18");
$bc->setQuiteZone("10");
$bc->setModuleSize("4");
//$bc->setFilePath('img/barcodes/');
$bc->paint($oid);
}
Here is a link to a working app outside Cake:
http://www.intraviewvs.net/barcode/show_barcode.php?code=12345678
Here is a link to the Cake install (use FF to view source):
https://www.intraviewvs.net/apps/orders/storeBarcode/12345678
The code in each case is identical, aside from the Cake-isms (turning
off render and layout).
Any insight at all would be stellar at this point...
