dynamically changing image sizes

[envexlabs]

Hey,

 

I have an uploader that uploads an image, then lets the user crop it to the size they want.

 

If the user uploads an image 800 x 600, and i set the height to 400 and width to 300, when i goto crop it, it screws everything up and renders out a solid color.

 

Anyone understand and possibly offer some help?

 

Thanks,
