You may use CImage class for the purpose, see CImage::Load [^] and, for instance, CImage::GetPixel [^].

Just in addition to CPallini's post.

If you decide to use CImage class you will notice that the GetPixel and SetPixel methods are slow. So if you need a fast pixel access you can use this[^] class with combination of CImage class.

Using CxImage[^] library could also be an option. Smile | :)

Just make sure you include <windows.h> (in example you can include it in stdafx.h, if you are using precompiled headers) before the include of zip.h and the errors must gone. Smile | :)

How to design a C (or C++) program that can extract object edges and detect the presence of straight lines.

DESIGN SPECIFICATION
1. Rescale the image down by the factor of 2, to reduce computational complexity of the
subsequent stages
2. Extract boundaries of objects using:
- 3x3gradient operators
- binary morphology
3. Detect the presence of straight lines and measure their orientation with the precision 3 degree
