Needed Source Code for Picture Size

[Marcus Jacobs]

Dear Group


I am currently working on a c program and I am in need of source code
that can determine the size in pixels (i.e. 600 x 600 pixels) for
various electronic picture formats (i.e. *.bmp, *.jpeg, *.jpg, *.tif,
*.png, *.gif). Does anyone know where I can access some source code
that can perform this task? Any help would be appreciated.

Regards
