SetPixels

[Monsterman22]

Hello.
I played with the ImageLib a little.
Just copy the color values of a bitmap to a textfile and redraw it anywhere.
Some may find it interesting.
Criticism is welcome.

Still I don't understand why SetPixel doesn't work at Button_click :

Sub Button_click
Bitmap.SetPixel(x,y,color)
End Sub

???

Probably because the form doesn't know the bitmap has changed and doesn't redraw it. Try Form.Refresh to redraw the whole form or Drawer.Refresh to redraw the part that has changed.

Try Form.Refresh to redraw the whole form

It works

Button_Click
Bitmap.SetPixel(X,Y,color)
Form1.Refresh
Form1.DrawImage(Bitmap.Value,0,0,100,100)
End Sub

You probably don't actually need the Refresh as you are doing a DrawImage after altering the bitmap which propbably does an automatic refresh. Try it and see.

Yes you are right Refresh is not needed
