I've just started to use X (X11R3) on SUN workstations. Previously I had
been using 'suntools' and had fiddled with NeWS and X a bit.
I'd like to be able to use some of the classier icons I've collected and
had been using with suntools. As a first pass, I just pulled out the
sunview icon header, put in my notion of a reasonable X icon header, and
used 'bitmap' to display the icon image. It looked almost right... but
not quite. It was as though each of the objects were mirror imaged, but
were correctly placed relative to eachother. Additionally, some of the
borders seemed out of place.
Here is the sunview version
/* Format_version=1, Width=64, Height=64, Depth=1, Valid_bits_per_item=16
*/
[bitmap here]
And here is what I replaced it with for X
#define Notes_width 64
#define Notes_height 64
static short Notes_bits[] = {
[bitmap here]
}
Now for the question: Is there a known way to do whatever bitmap translation
is necessary here? Have I missed the obvious?
Thanks in advance

Take a look at contrib/clients/pbm of the X11R3 distribution. It contains a set of routines for converting to and from a portable bitmap format developed by Jef Poskanzer. You can convert the Sun icon to the portable bitmap and then from the portable bitmap to X11 bitmap format. It supports a number of other formats as well (macpaint, GIF, Sun raster etc.) It also contains a number of utilities for manipulating bitmaps as well. (Cut and Paste, inverting, flipping). I've found it very useful. Michael S. Ovington Software Architecture & Engineering 1600 Wilson Boulavard, Suite 500 Arlington, VA 22209 (703) 276-7910

Here is a quick hack I did to convert bitmaps from Sun to X (use it any way you like) : --------- CUT HERE ---------- /* s u n t o x b m . c Convert Sun icons to X bitmaps. usage: suntoxbm < file.icon > file.xbm */ #include <ctype.h> main(argc, argv) int argc; char **argv; { char c, s[100], *name = argv[1]; int w, h, x, n; scanf("%*s%*s%*[^=]%*c%d%*[^=]%*c%d%*s%*s%*s%*s", &w, &h); printf("#define %s_width %d\n", name, w); printf("#define %s_height %d\n", name, w); printf("static char %s_bits[] = {\n"); n = 0; printf(" "); while ((c = getchar()) != -1) { if (c == 'x') { x = gethex(); if (n == 12 ) { printf(",\n "); n = 0; } else if (n) printf(", "); printf("0x%02x, ", reverse((x & 0xff00) >> 8)); printf("0x%02x", reverse(x & 0xff)); n += 2; } } printf("};\n"); } int reverse(x) int x; { int i, y = 0; for (i = 0; i < 8; i++) { y <<= 1; y |= ((x & 1) == 1); x >>= 1; } return y; } int gethex() { int i, c, x = 0; for (i=0; i < 4; i++) { x <<= 4; c = getchar(); if (isupper(c)) c = tolower(c); if (c >= 'a') x += c - 'a' + 10; else x += c - '0'; } return x; } -- -- Joakim Sernbrant, Royal Institute of Technology, Stockholm, Sweden -- Internet: d87-jse@nada.kth.se --
