Re: Accessing another extensions resource.. possible?

Thank you so much everyone. I just got back from vacation so I apologize for my slow reply. I was able to get it to work wonderfully. Since I had no desire to use the gd functions in my extension (I just needed raw access to the pixel data) and to avoid compilation problems outside the source tree I just copied the image structure defined by php's gd extension into my code directly. It's kinda the easy way out but it works so well. I'm not quite at a point where I can show it but hopfully it'll be ready within a month. Thanks again everyone!
