Hello,

I would like to do a product personnalisation system where we can put on a product an image / text simulation with picture-size / picture-emplacement managed (maybe with a sql database).

i found something's looking what i want but it's in PHP :

http://www.shirtcity.com/shop/

i want do the same but in ASP.Net / VB..

I did already something to change color of a picture (png) and place it on another product picture, here's the function that paint a picture :

Public Function ChangerCouleur(ByVal Img As Image, ByVal Couleur As Color) As Bitmap

        'Création d'un 'Graphics' à partir du 'Bitmap' passée en paramètre
        Dim gr As Graphics = Graphics.FromImage(Img)

        'Création d'un mappage
        Dim map(0) As System.Drawing.Imaging.ColorMap
        map(0) = New System.Drawing.Imaging.ColorMap()
        map(0).OldColor = Color.Black
        map(0).NewColor = Couleur

        'Création d'attributs d'image, avec le mappage créer juste avant comme contenu 
        Dim myAttributs As New ImageAttributes()
        myAttributs.SetRemapTable(map)

        'Dessin du motif à la couleur passée en paramètre
        Dim Rect As New Rectangle(0, 0, Img.Width, Img.Height)
        gr.DrawImage(Img, Rect, 0, 0, Img.Width, Img.Height, GraphicsUnit.Pixel, myAttributs)

        'Redimensionnement
        Dim Final As Image
        Final = ScaleByPercent(Img, 20)

        'Libération des objets de la mémoire
        gr.Dispose()
        Img.Dispose()

        Return Final

    End Function

But maybe do u have better ideas than me ? Or links to follow ?

Thanks :)
