Size of UIImage after UIImagePickerController

I'm trying to figure out what the size of a UIImage is after a picture is taken with UIImagePickerController and how to properly scale the image taken. If I wanted the camera to take a picture 100pt x 100pt every time, how would I accomplish this?

I consulted the documentation for UIImagePickerController but it didn't have anything on image size

I believe something like this is what you're after. Please let me know though if I'm wrong.

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
    CGFloat var1;
    CGFloat var2;

    if (image.size.width > image.size.height){
        // Landscape
        CGFloat aspect = image.size.width / image.size.height;
        CGFloat height = ceilf(100.0/aspect);
        var1 = 100.0;
        var2 = height;
    }
    else if (image.size.height > image.size.width){
        // Portrait
        CGFloat aspect = image.size.height / image.size.width;
        CGFloat width = ceilf(100.0/aspect);
        var1 = width;
        var2 = 100.0;
    }
    else{
        // Square
        var1 = 100.0;
        var2 = 100.0;
    }

    UIGraphicsBeginImageContextWithOptions(CGSizeMake(var1, var2), NO, 0.0);
    [image drawInRect:CGRectMake(0, 0, var1, var2)];
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
}
