Re: Display Dynamic Images in Cake??
Did you set the headers correctly (content type etc)? Do you have a space (or more than one) appearing at the beginning of your image file which would cause these problems? What PHP barcode generation library are you using?

Re: Display Dynamic Images in Cake??
Hey Wayne, The image is a PNG so I am using the content-type MIME for PNG. I do not know how any spaces could work their way in there. The same code works outside Cake. It's called rDataMatrix and relies on the bundled GD Library. Again, outside Cake, nothing but joy. Inside Cake, one of my few moments of misery. There must be something with the framework that is altering the image information, or I need to do one more step to keep the image in the proper format? Even when I store to a file, the image is corrupted. On Nov 27, 2:42 am, Wayne Fay [EMAIL PROTECTED] wrote: Did you set the headers correctly (content type etc)?

Re: Display Dynamic Images in Cake??
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...

Re: Display Dynamic Images in Cake??
OK, now I am just talking to myself, but I have had some stellar insight for anyone following along. The problem is apparently not in the display of the image, but in the generation of the image. I remember having some issues with global variables in the framework from time to time, and I think that's the culprit here. I will post the final findings for any interested parties... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Cake PHP group.

Re: Display Dynamic Images in Cake??
Looks like you are messing with it now - there is an obvious print_r
and br/ before the file data now.
Are you calling exit() after the file data is output, or otherwise
ensuring that cake doesn't attempt to render a view?

Re: Display Dynamic Images in Cake??
Indeed the problem was globals not being seen globally. I added some global statements and joy is mine again.
