Possible bug with GD implementation
11 September 2007 at 4:32pm Last edited: 14 September 2007 2:03pm
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.phpimagecreatetruecolor(0,0)
line 47 of GD.phpGD->croppedResize(,)
line 175 of Image.phpImage->generateCroppedImage(Object,,)
line 150 of Image.phpImage->generateFormattedImage(CroppedImage,,)
line 125 of Image.phpImage->getFormattedImage(CroppedImage)
line ofcall_user_func_array(Array,Array)
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 http://doc.silverstripe.com/doku.php?id=imageupload and still no luck - three hours later...
. Anyone have any ideas of what I'm doing wrong, or is this a bug?
Cheers

This is a bug in the template system - try:
[html]
<% control image_one %>
$CroppedImage(200,130)
<% end_control %>
[/html] -

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!
