bmp file format [RESOLVED]

OK, my main question is, i have a series of 1's and 0's, and was wondering how to convert them into a black&white .bmp form, so i can view them from Paint or any other picture viewing program.
Thanks

Also, of similar topic, what do you need to create your own midi file? is it just notes & their length, and which instrument plays it? thanks.

To create the bitmap you could loop through your data, and draw the pixels using SetPixel.

Just need to do something like(tested code):
VB Code:
```
Private buftxt(32696) As String
'my picture had that many pixels
Dim X As Long, Y As Long
For i = 0 To ubound(buftxt)
Picture1.PSet (X, Y), buftxt(i) * 16777215
X = X + 1
If X > Picture1.ScaleWidth - 1 Then
X = 0
Y = Y + 1
End If
DoEvents
Next
 
'to fill buftxt with random data:
 
For X = 0 To 32696
buftxt(X) = Int(Rnd * 2)
Next
```
Pset was fast enough for me.

Good luck,
