Only Image objects have GD functions.

Ok was afraid so.
I dont really want to change my code, because i want to be able to upload all kind of files with 1 page type.
I'll use some script to generate the thumbs.

Here's a possible fix. In Download.php:
public function onAfterWrite() {
parent::onAfterWrite();
if($this->FileID) {
if(in_array($this->File()->Extension, array('jpg','jpeg','gif','png'))) {
$f = $this->File();
$f->ClassName = "Image";
$f->write();
}
}}
That might work. Might be a few syntax errors in there, but hopefully you get the gist..

Dude it worked
your great!
For those in need of this code:
template:
<% control File %>
<a href="$URL" target="_blank">
$SetHeight(110)
</a>
<% end_control %>Code that extends DataObject:
class yourNameHereextends DataObject {
....
public function onAfterWrite() {
parent::onAfterWrite();
if($this->FileID) {
if(in_array($this->File()->Extension, array('jpg','jpeg','gif','png'))) {
$f = $this->File();
$f->ClassName = "Image";
$f->write();
}
}
}}

Glad to hear it. The only thing I'm wondering is, if your template is calling $SetWidth on every File object, then why not just cast the relation as Image, and save yourself all that trouble?
Why does it have to be casted as File?

Well.. I wanted to have a minimum amount of pagetypes.
So the goal was to have 1 downloads page type.Im using this template to upload images, but also pdf's, doc's, zips etc.
The template checks the extensions and decides to put a nice image (with a big icon of the filetype) or just render a thumbnail.
The template checks alot of extensions, but this is an example for those in need of code.<% control File %>
<a href="$URL" target="_blank">
<% if Extension==pdf %>
<img src="../../../themes/name/images/icons/pdf_logo.jpg" />
<% else_if Extension==jpg %>
<% if RatioChecker %>
$SetWidth(150)
<% else %>
$SetHeight(110)
<% end_if %>
</a>
<% end_control %>Finally, i also want to check the image ratio. Because when the width is smaller then the height the images doesn't fill my overflow box (which is 130px x 80px)
im trying something like this, but it doesn't work.
function RatioChecker() {
if ($this()->getWidth() > $this()->getHeight()){
return false;
}else{
return true;
}
}template
<% if RatioChecker %>
$SetWidth(150)
<% else %>
$SetHeight(110)
<% end_if %> -

there is already a function for what you need
instead of
<% if RatioChecker %>
$SetWidth(150)
<% else %>
$SetHeight(110)
<% end_if %>you use:
<% SetRatioSize(150,110,1) %>
docs say:
SetRatioSize(80,80) // **New in 2.4** returns an image scaled proportional, with its greatest diameter scaled to 80pxand i belive, if you add a 1 as 3rd param, it will turn the function around, so it is "with its smallest diameter scaled to 80px"
