Hi Tim, I'll have a go at hosting CVS if you like, I've yet to determine what my cable connection is like for such things so I'll stick a recent patch of xfractint in and set you and Jon up with accounts on my cygwin setup so you can use ssh to access the repository. I've also written up some quick howto's for the other UTron project coders so I'll post them as well. Probably get it done over the weekend, watch this space :-) >On another subject, what is the problem re Fractint and XP? Probably the same as with NT and win2K, they all use a HAL type setup so direct hardware access is out. Though 2K and XP can both use directx. I wonder if any windows whizz out there could do a directx wrapper in fractint for video and keyboard access, that'd be cool :-) Cheers, Robin. ------------------------------------------------- This mail sent through UK Online webmail

A problem compiling Xfractint 20.2.04
by Scott D. Boyd 05 Jun '02

05 Jun '02

Tim or Jonathan, I've *finally* gotten around to trying to compile Xfracint 20.2.04. Seems like curses.h is missing. Should I grab a copy from an older version? Below is the last 3 lines from the "make" command: gcc -I. -DXFRACT -DNOBSTRING -g -DBIG_ANSI_C -DLINUX -Os -c -o realdos.o realdos.c realdos.c:10:20: curses.h: No such file or directory make: *** [realdos.o] Error 1 Until later, Scott Boyd

I'll look thru my kernel source, and see if I can find it. Later, Scott

What Linux environment are you using? Curses.h should be includied. Maybe you have a missing curses (or ncurses) package. We did determine that the termcap library is not needed. Tim

Version 20.2.05?
by Jonathan Osuch 29 May '02

Tim, Are you/we going to turn the floating point only work into version 20.2.05? I found out that Mandrake 8.2 needs a patch to let you install it on a pentium machine. That was the problem I was having with my desktop. Are you passing through Iowa in June? Jonathan

Version 20.2.03 or 20.2.04
by Paul N. Lee 16 May '02

I may have missed something, but just in case not... Could someone explain why the download of the "fradev20.2.04.zip" contains a different executable than the "fradev20.2.03.zip", but both show 20.2.03 in the online Help??

For I would be interested in as complete a set of FractInt executables as possible, with any and all sources that are available.

Re: [Fractdev] Xfractint color cycling

Hi Jonathan, > That actually looks like a palette change to me. But, I don't > speak Windows. It's not a REAL palette change. I just have an array of RGB values for each iteration and I rotate this artificial palette. I then write the new value to each pixel (I may have forgotten to put this code segment into the original message. If I did, I apologise). So here is the rest of it: local_width = WIDTHBYTES((DWORD)width * (DWORD)bits_per_pixel); for (j = 0; j < height - 1; ++j) { i = ((long) (height - 1 - j) * (long) (local_width + 3 - ((local_width - 1) % 4))); k = ((long) (height - 2 - j) * (long) (width + 3 - ((width - 1) % 4))); for (m = 0L; m < width; ++m) { colour = (DWORD) (*(wpixels + k + m)); if (!TrueColourFlag) colour &= 0x000000ff; n = colour + colour + colour; pointer = m + m + m + i; *(pixels + pointer + 0) = *(PalettePtr + n + 2); *(pixels + pointer + 1) = *(PalettePtr + n + 1); *(pixels + pointer + 2) = *(PalettePtr + n + 0); } } Hence you can see that I am actually updating each pixel every step of the rotation.

Hi Guys, I have had colour cycling working in MANPWIN which is true colour without the use of palette changes. It requires a fast PC and just swaps a lot of memory around. /*********************************************************************** **** Rotate palette ************************************************************************ ***/ void rotate_palette(HWND hwnd, int dir, int delay) { long i, k; int j, m; long local_width; DWORD RotateLength; DWORD colour, n, pointer; RotateLength = (TrueColourFlag) ? maxit + maxit + maxit - 6 : 768 - 6; if (dir == 1) { memcpy(temp_palette + 3, PalettePtr + 3, RotateLength); // >> 3 bytes memcpy(temp_palette, PalettePtr + RotateLength + 3, 3); // rotate 3 bytes memcpy(PalettePtr + 3, temp_palette, RotateLength + 3); // back to palette } else { memcpy(temp_palette, PalettePtr + 6, RotateLength); // >> 3 bytes memcpy(temp_palette + RotateLength, PalettePtr + 3, 3); // rotate 3 bytes memcpy(PalettePtr + 3, temp_palette, RotateLength + 3); // << 3 bytes } } Comments???
