imread image sizing

[Ross Vandegrift]

Hello everyone,

        I'm working on an image analysis project, and am using imread to
read in a color 640x480 JPEG file and sample some points.

        Oddly though, when read in and displayed, the graphic is
displayed as 320x240.  If I manually run "display eye.jpg", the image is
loaded as 640x480.  I've tried setting "-size 640x480" and "-sample
640x480" in the options, neither one helps.

        Here's how I'm loading/displaying my image:

[red, green, blue] = imread('jpg:eye.jpg', ["-size 640x480";]);
red = red / 255;
blue = blue / 255;
green = green / 255;
imshow(red, green, blue)

        It's not a critical problem or anything - I'm still able to work
on the project at 320x240, but is there something I can do to get
640x480?

Thanks!
