. WriteFile.writeBytes8:
     I expected as output a 8bpp image as output
     I see instead a invalid file format with 4.9Mb. I tried to open the file using Gimp 2.6 (attached image) but received a error dialog;

. WriteFile.writeMem:
     I expected as output a array of bytes filled with the specified format
     I see instead a null value
