problem creating a 1bpp bitmap from a byte array in vb.net

Question

I'm having a problem creating a bitmap from a byte array in vb.net.
I get the pixel data from a GoPro as 1 bit per pixel data.
It looks like this:

0 0 0 0 0 0 0 0 1 1 5D 6C 63 0 5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 FF FC 4 0 1C 70 71 C1 0 4 E 0 36 DA DB 61 77 74 4 0 36 D8 DB 63 77 74 11 0 36 D8 DB 63 77 74 E 0 36 DA DB 63 77 74 20 80 36 D8 DB 61 77 74 9F 20 1C 70 71 C1 0 4 40 40 0 0 0 1 FF FC 3F 80 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 FF FF FF FF FF FF FF F0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 C 36 3 E3 F0 0 0 0 C F6 7 FB FC 0 0 0 C C0 6 1B C 0 0 0 D 80 0 1B C 0 0 0 F 80 3 FB C 0 0 0 E 0 3 E3 C 0 0 0 D 80 6 3 C 0 0 0 D C0 6 1B C 0 0 0 C C0 6 1B C 0 0 0 C 30 3 E3 F0 0 0 0 C 30 3 E3 F0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 FF FF FF FF FF FF FF F0 FF FF FF FF FF FF BF F0 F0 7 FF FF FF FB BB F0 E0 3 9F E0 7F FD F7 F0 E7 3 1F E0 7F FF 1F F0 E7 2 1F E7 FF FE EF F0 E7 2 1F E7 FF F2 C9 F0 E0 2 1F E7 FF FE 8F F0 E0 2 1F E7 FF FF 1F F0 E0 3 1F E7 FF FD F7 F0 E0 3 9F E7 FF FB BB F0 F0 7 FF FF FF FF BF F0 FF FF FF FF FF FF FF F0 FF FF FF FF FF FF FF F0 0

The first 15 bytes are the repetition of the request. This and the last byte are cut off

With the following code I convert the data into a bitmap:

Private Function GetBitmap(lcdContend) As Bitmap
    Dim lcdBytes(599) As Byte
    Dim split = lcdContend.Split(" ")

    For lci = 0 To 599
        lcdBytes(lci) = Convert.ToByte(split(lci + 15), 16) Xor 255
    Next

    Dim img = New Bitmap(64, 75)

    Dim bmd As BitmapData = img.LockBits(
       New Rectangle(0, 0, img.Width, img.Height),
       ImageLockMode.WriteOnly,
       PixelFormat.Format1bppIndexed)

    Marshal.Copy(lcdBytes, 0, bmd.Scan0, lcdBytes.Length)

    img.UnlockBits(bmd)

    'img.RotateFlip(RotateFlipType.Rotate180FlipX)

    Return img
End Function

The bitmap is 64px wide and 75px high and is 600 byte in size I then load the bitmap into a PictureBox. The result looks like this: Error display

The whole picture is shifted 4 pixels to the left. If I rotate and flip the image, the whole picture is also shifted 4 pixels to the left. flipped How do I get the missing 4 pixels column on the Image? I've tried so much, including converting to 24bpp. Everything results in the same result

PS: The data is okay, I converted it into bits by hand and drew a bitmap from it by hand. All the data is there.

I thank you!

Answer 1

The display is only 60px in width. My mistake. So everything is right. Thanks stevec
