Cool, thank you. I actually ended up getting a little help from a mentor, and he basically showed me the code you just wrote :) I'll have to look up Smagick, but if nothing else, this will be fine for the time being.<br><br>Thanks,<br>RS<br><br>> Date: Mon, 11 Jan 2010 07:06:35 +0100<br>> Subject: Re: [Seaside] On Forms, PNGs, WAFiles, and ByteArrays<br>> From: philippe.marschall@gmail.com<br>> To: seaside@lists.squeakfoundation.org<br>> <br>> 2010/1/11 Robert Sirois <watchlala@hotmail.com>:<br>> > I wrote a simple form to upload images to the server, and I would like to<br>> > create thumbnails for them automatically.<br>> ><br>> > The way I ended up doing it is as follows:<br>> ><br>> > saveEntry<br>> > | aForm newForm |<br>> ><br>> > " add original file under name blahblahPng or whatever the image type is<br>> > "<br>> > UGFileLibrary addFileNamed: title,'Png' contents: uploadedFile contents.<br>> ><br>> > aForm := (PNGReadWriter createAFormFrom: uploadedFile contents) first.<br>> ><br>> > " create thumbnail and save under name blahblahThumbPng "<br>> > newForm := aForm scaledToSize: (Point x: 50 y: 50).<br>> ><br>> > " what I would have liked to do here is add the thumbnail to the file<br>> > library "<br>> ><br>> > " add item to art section "<br>> > UGArt addImage: (<br>> > (UGArtItem<br>> > title: title path: title,'Png') artist: self session user;<br>> > imageForm: aForm; thumbForm: newForm; yourself<br>> > ).<br>> ><br>> > As you can see, I ended up using WAImageTag #form: rather than a url from<br>> > the file library (or server directory, preferably).
