I've been trying to set up some images to display cropped (using CroppedImage) rather than resized (using SetWidth) thumbnails. It seems that no matter what I do, I can't get it to work.

Something like $image_one.SetWidth(200) works fine, displaying the image resized to 200px wide maximum.

If I try $image_one.CroppedImage(200,130), I get a wonderful fatal error:

FATAL ERROR: imagecreatetruecolor() [function.imagecreatetruecolor]: Invalid image dimensions
At line 47 in /Applications/MAMP/htdocs/ss/sapphire/filesystem/GD.php

line 47 of GD.php

line 175 of Image.php

line 150 of Image.php

line 125 of Image.php

line of

line 145 of Object.php

...And so it goes. You get the picture :)

It seems that the two sizes aren't getting passed for some reason. If I only try to pass 1 size (eg $image_one.CroppedImage(200)), the error at least recognises that one size has been passed with the second size missing. This seems strange.

I've tried using the methods described in and still no luck - three hours later... :(. Anyone have any ideas of what I'm doing wrong, or is this a bug?

This is a bug in the template system - try:

<% control image_one %>
<% end_control %>

I believe the template parser can't handle $Property.Subproperty(Parameter). More specifically it's the SSViewer class. If you're feeling lucky you could try implement this. :-)

It is a little confusing.

That worked a treat Andy, thanks :)

And I'd love to try to implement it, but I'm just a lowly designer still learning PHP... It seems to be similar to learning a foreign language: I can understand most of it, but speaking it is very hard!
