Array to images?

[freezway]

I'm fairly new to c++ and I've got a big array of int's that I want to use as the Red(or green/blue) value of an image (gif, png, anything is ok.) I found a nice lib called PNG writer, but I cant get it to install. I have to clue where to start on this. Also, it has to work on Linux.

Which distro do you have?
You may also look for libpng http://www.libpng.org/pub/png/libpng.html

I'm using ubuntu 9.10 64 bit.

is there a simpler way, or better documentation?

On Ubuntu 9.10, Synaptic shows me these packages: libpngwriter0c2, libpngwriter0-dev
They seem to be the library you were looking for

BTW libpng packages ( libpng12-0 and libpng12-dev ) are supported by Canonical while those of pngwriter are not

is what I get from trying to compile the example with libpngwriter0c2, libpngwriter0-dev installed
