[Dev-C++] Read an Image and convert it into 2D Array.

[Benson M. <ben...@gm...>]

Hello Everyone,

Is anyone aware of how to read a greyscale image and convert it into a 2D
array of 256 by 256 in C++.

I would appreciate your contribution on this.

Kind regards
Benson.

Too little information given!

If the image is in any known image format (GIF, JPEG, TIFF, PCX, BMP, ...)
then you need to locate a graphics library that contains code to read that
format.

If the data is in a raw binary file or stored as ASCII, then you have to
write your own code.

There is no way anyone can help you, if you don't take your time and
clearly specify your problem!

Thank you Per for your reply...

The image is in PGI (portable Greymap Image) and I am stuck in converting
the image to a 2D array inorder to do the various needed manipulations.

Kind Regards

Benson.
