Hi
This post follow this one : http://www.purebasic.fr/english/viewtop ... =4&t=47500
I think that now the alpha pixels aren't white, but they are black or grey.
As you can see on that image :
I have used the ResizeImage(#PB_Image_Smooth) with PB 5.31 and pb 5.40b3 (here is a comparaison on the same reduction made in photoshop to see the difference).
With pb5.40b3, we can see a little black border in the image.
Perhap's the reduction seems to "mix" the original color with black, when the alpha of a pixel is < 255.
PS : (It remind me the "premultiplied mode" for alpha
