This doesn't look right. You need to call GetBitmapBits the second time
with "size" returned from a previous GetBitmapBits call, just like you do
in SetBitmapBits.

If I do that, I get an X Error:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  73 (X_GetImage)
  Serial number of failed request:  34307
  Current serial number in output stream:  34307


The bitmap in question in Avrstudio from Atmel is a four bit one. With the
code above, serveral errors like:
err:x11drv:X11DRV_CreateBitmap Trying to make bitmap with planes=1, bpp=4
err:x11drv:X11DRV_CreateBitmap Trying to make bitmap with planes=1, bpp=4
err:x11drv:X11DRV_CreateBitmap Trying to make bitmap with planes=1, bpp=4
err:x11drv:X11DRV_CreateBitmap Trying to make bitmap with planes=1, bpp=4

are produced. 

B.t.w. to get Avrstudio to run until that error happens, start it like
env WINEDLLOVERRIDES=msvcrt,msxml3,ole32,oleaut32,rpcrt4,urlmon=n /spare/bon/wine/wine/wine AvrStudio4/AVRStudio.exe
