Besoin d'aide et vite si possible !!!

Voilà le code source, jessaye d'enregistrer le picture3 (voir source) car quand je fait savepicture, il bug. Merci d'avance
il necessite 3 picture box et une listbox avec 6 choix dans la list.

code source:

Private Sub MERGE(INVERTED1 As Boolean, INVERTED2 As Boolean)

Dim y As Long
Dim R1 As Integer

Picture3.Cls
Picture3.Height = Picture1.Height
Picture3.Width = Picture1.Width
For X = 0 To Picture1.ScaleWidth
DoEvents
For y = 0 To Picture1.ScaleHeight
'on regarde les valeurs RGB de la première image
GET_COLORS Picture1.Point(X, y), R1, G1, B1, INVERTED1
'on regarde les valeurs RGB de la seconde image
GET_COLORS Picture2.Point(X, y), R2, G2, B2, INVERTED2

Picture3.PSet (X, y), RGB((R1 + R2) / 2, (G2 + G1) / 2, (B2 + B1) / 2)

Bonjour ,
Je te propose une solution :
Tu a cent doute remarque que suit tu reduit la fenetre et que tu l'agrandi l'image disparait !
pour cela il y a une propriete a definir pour que windows redessine l'image lor de la restoration de l'image ::
' Active la propriété AutoRedraw.
AutoRedraw = True

De plus pour aller BEAUCOUP plus vite dans le tretement de tes image tu peut utiliser une echelle un pixel : le tres gros aventage est que tu gere en 1024*768 1024 points en horisontal et 768 en vertical contre respectivement 14760*10920 en TWIP (echel par defaul dans les projet VB)
' Définit l'échelle en pixels.
ScaleMode = vbPixels



Voici ton prog modifier par mes soins :
pour enregistere l'image DBclick sur le font de la form
l'image est alors enregistree sous c:\TEST.BMP

Voila
(tu peut peut etre travailler sur une autre form pour exoter tes images ...

TFlorian.

Merci tu me sauve la vie......(lol)
Nan franchement, c impec, ca marche......merci
