The Image Manipulation class and image blobs from the database... |

Hi folks! I've got a tiny question. I've written an Google Gears based multi-file uploader. (soon I'll release it to the public, but if you're interested - drop me a line! [email protected]) The upload controller who handles the uploaded bytes saves the blob bytes one by one into a database. Well, I know there's a lot of discussion going on about saving to a database or a file system and the file system is getting the better of it, but trust me, for a lot of valid reasons I chose for a database in this project. But now, I need to manipulate the files on output. (live, thus) Imagine three different methods in a controller, one outputting a image thumbnail, the other a 'regular' image size and the third outputting the original. Like this: Code: >> http://my-app.com/index.php/download/thumbnail/9611cada1e54eef43935421c1851a6da The code for the 'original' method is easy: Code: function original($uid) { But for the other two methods I'd like to use the Image lib. Is there a way? It seems that the image lib only accepts real file names, no blob strings... I hope you can give me a hand here! thanks! Fabian

Looking through the Image Lib, you would need to hack it up in several places to use a database blob instead of an actual image file. I think this is because the underlaying graphics libraries require real image files and not image information. It's possible to save the information to a temporary file and then process it, although it's not direct, it would achieve what you want. Other than that, it would take a bit of effort to modify the image library to take image information.

Hi Cro_Crx, Thanks for your reply, but I already got it worked out. My code: Code: function original($uid) { |
