Describe tips for implementing the feature Define dimension in src/features.h. Implement dimension in src/features.c. Use the data from the function read_image_data from <estia-image.h>.

int read_image_data(const char *filename, unsigned char **data, int *width, int *height, int *channel_count);

The width is stored in width and the height is stored in height. Read the wiki Call dimension in src/main.c. See the helloworld example to correctly call the function.

if ( strncmp( configuration.command, "dimension", 9 ) == 0 ) {
    /* dimension() function is defined in feature.h and implemented in feature.c */
    dimension( configuration.filenames[0] );
}

Possible Variation

Space are permitted between the dimension: and the actual value. Space are permitted around the ,
