Example #1

File: im_png2vips.c Project: Ikulagin/transmem

static int
ispng( const char *filename )
{
	unsigned char buf[8];

	return( im__get_bytes( filename, buf, 8 ) &&
		!png_sig_cmp( buf, 0, 8 ) );
}

Example #2

static int
isppm( const char *filename )
{
	unsigned char buf[2];

	if( im__get_bytes( filename, buf, 2 ) )
		if( buf[0] == 'P' && (buf[1] >= '1' || buf[1] <= '6') )
			return( 1 );

	return( 0 );
}

Example #3
