I read the image with:
W=double(imread('rose32.bmp'));
Then: imshow(W,[]); or imshow(W);
But, Showed image seems to invert of original image. How Can I solve this problem ? It is a Matlab problem ?

You are treating the image as if it is a binary or RGB image, but it is not: it is an index (pseudocolor) image. You can see this by using
iminfo('rose32.bmp')
and noticing the "ColorType: 'indexed'"
A proper way to display it:
[W,cmap]=imread('rose32.bmp');
image(ind2rgb(W,cmap))

If the Colormap shows up as nonempty then it is a pseudo color image not a grayscale image. .gif are mostly pseudo color.
