making a bitmap file from arrays

[Jeroen Ceuppens]

I have the colormap (ARGB, 8bit , so every color from 0 to 255) , put it in
an array (1dim)

I have the pixel date (array 640x480)

What is the best way to make with these array's a bitmap file?

Thx
Jeroen

Jeroen,

Can you clarify your question? Are you trying to create a .bmp file or a
file in any other standardized bitmap graphics file format or are you simply
looking for a way of storing your array (the raw pixel data) in a file?

Regards,
Alex

Hi,

All you have to know is the format a BMP file is organized, after that you
can create your own file with an .bmp extension and write your data
according the format using a FileStream object.

Hope this help,

Here's a quick link of how to create a bitmap programmatically. You'll have
to piece together how you're arrays fit into the SetPixel methods...

Having said that, I'll mention that SetPixel is very slow (well, when
looping 4 million times it is, not sure for 300,000 times to make a 640x480
bitmap). I suggest using unsafe code, i.e. pointers. This site has a very
good description of how to set pixels by using pointers. I would get your
code working according to the above link, then if you need the speed
optimize it as follows:
