To create bitmap file

[Kiat leong Len]

I am using HP-UX 10.20, B180L machine.

I need to create a bitmap file which stores some calculation graph. I could use
ANSI C or C++.

Where can i find information on the above subject?
What command can i use?
What is the structure of bitmap file?
Anybody has some sample programs?

Thanks.

I'm not clear on exactly what you are trying to accomplish. Can you explain
what you mean by bitmap
file for a calculation graph, are you thinking .jpg, .gif or something else???
Are you trying to take an
equation and draw something???

Any additional info would be good.


Thanks

Hi,
Actually, I am trying to create a graphic profile to indicate the quality of a
process. Using bitmap, i could use each pixel and by manipulating the color of
the pixel, i could display the quality of the process. I intend to use 1440x200
pixels for the bitmap. Another way to visualise what i am trying to achieve is
the thermal visual technology where the red color tells you there is heat.
