Imageresizing return negatif image - imageresizer

Question

I use imageresizer (v3) since 3 years now on an heavy image website (Real Estate) with non problem. I update to version 4 and now I have some problem. When a resize, some image output in negative style.
Here are my configuration:
<resizer>
<image404 default="~/404/default.png" chaletfr="~/404/fr_chalet.png" condofr="~/404/fr_condo.png" maisonfr="~/404/fr_maison.png" terrainfr="~/404/fr_terrain.png" locationfr="~/404/fr_location.png" chaleten="~/404/en_chalet.png" condoen="~/404/en_condo.png" maisonen="~/404/en_maison.png" terrainen="~/404/en_terrain.png" locationen="~/404/en_location.png"/>
