after several hours ,I think maybe 2 possibility
exist.but i am not sure .i still need some help.
1.my raw rgb format may be not right
i get the raw pic through a tool bmp2raw which convert
the bmp to 8bpp rgb. And gl_putbox need a pixmap .I
dont know if 8bpp rgb is pixmap? if not ,why only the
hue is abnormal?
The following is from man page for gl_putbox;
Pixmaps are in row-major order. The source pixmap
memory has the size w * h * BYTESPERPIXEL.
2.Maybe i dont config the video card right
I read the manpage several times .but i didn't know
how i can do yet.
so, here give some information .Hope it will be useful
to resolve this problem.
monitor config in libvga.conf is default:
Horiznsync 31.5 35.5
vertRefresh 50 90
runtime info:
Using Riva driver, 32768kb .Type: nv4,RivaTNT/RivaTNT2
svgalib 1.4.3
the result of vgatest:
10 640x480x256 ok
11 800x600x256 ok
12 1024x768x256 beyond the frequence of refresh
35k/43hz
17 640x480x32k ok
18 640x480x64k ok
20 800x600x32k ok
21 800x600x64k ok
23 1024x768x32k =12
24 1024x768x64k =12
34 640x480x16m ok
35 800x600x16m ok
36 1024x768x16m =12
but in my testprogram,if I setmode to 24 ,it will give
"mode not avalible". mode 23 is ok. and all l024x768
mode get "1024x768x256 beyond the frequence of
refresh 35k/43hz "
