Thread: buffered image to RGB array

My final goal is to import a JPEG image and convert it into an array that follows an RGB format. The array I want the image to go to is image[2][height][width]. Where image[0][height][width] is the red color scale from 0 to 255, image[1][height][width] is the green color scale from 0 to 255 and image[2][height][width] is the blue color scale from 0 to 255.

Below is the code I have so far. Basically, I can import an image to the "buffered" image, and I can write an image to a PNG file from an array of my choosing (in this case the array named "image") that follows the RGB format. But I can't convert the buffered image to an array. Does anyone know the missing code I need?

Thanks!

getRGB worked! Thanks...
