Hi Werner,

One possibility is the "xbm" format, much used for program
icons in X, since these use only ASCII characters. It depends
what you mean by "binary2, though.

A typical xbm file has structure (quote):

   #define splashScreen11_width 508
   #define splashScreen11_height 372
   static char splashScreen11_bits[] = {
   0x00,0x00,0x00,0x00,0x00,0x00,...
   ...
   ...,0x00,0x00,0x00};

i.e. it looks just like a C array initialisation.
Its contents are "binary" in as much as the data
are expressed as hexadecimal bytes, but these
are given the standard C representation in ASCII.
So of course you can change them using a text editor.

[The above defines the Adobe Acrobat Reader splash
screen, splashScreen11R.xbm].

By the way, you don't say what Gaius's png is for.
Can we have a look at it? <pretty please>

Ted.
