As said, do multiple reads per line.
readline ( my_file , current_line ) ;

read ( current_line , incoming_pixel3 ) ;
You won't need to ask if you reviewed the description of textio package in vhdl LRM.

there is no way to do this easily in vhdl. vhdl is not set up to do File io nicely other than text.
What file are you trying to read? For every file you can use the ENDFILE() function to see if you have reached the end of a file:
while not ENDFILE(my_file) loop
You could use this lo

Ill assume each value is stored on a seperate line:
type some_array_t is array(integer range <>) of integer;
signal ar : some_array_t(0 to 99); --could be a varaible
--inside a process
file f : text open read_mode is "my_file.txt";
variable inline : line;
for i in ar'range loop
